The Cloud Offers Communications as a Service

By: John Shepler

The migration of everything to the cloud has coined a new phrase: “as a service”. This implies the business model of pay-as-you-go rather than owning vast capital equipment and software resources and the support staffs that go with them. You still need in-house support for your staff and to liaise with your cloud service provider, but you no longer have to be involved in all the nuts-and-bolts that make the system work.

In addition to the backroom business software humming along in the background, the cloud now offers to take on your electronic communications with the idea of offering a more features for less cost that you’d likely have if you tried to run everything in-house. The name of this new opportunity? Why, Communications as a Service, of course.

Two Flavors of Communications as a Service
If you think of communications as “the telephone”, you are partially right. The landline phone has been the mainstay of business for over a century. It has been joined by the FAX machine to send documents over those same phone lines and the mobile phone that frees us from the wires. The marriage between phones and computers has expanded options to include instant messaging, audio, video and web conferencing, texting, file sharing, call routing and recording, call analytics and integration with business applications like CRM and project management software.

Communications as a Service or CaaS splits off into Unified Communications as a Service or UCaaS and Contact Center as a Service or CCaaS. What’s the difference? UCaaS is intended for use within the company for team collaboration CCaaS is for communicating with customers. You can think of UCaaS as replacing the old PBX business phone system and CCaaS as a technical upgrade to the old call center phone system.

How Unified Communications as a Service Works
With UCaaS the PBX in the closet down the hall or the key telephone set on your desk is gone. If you have a desk phone it connects to your LAN using VoIP rather than its own proprietary phone network. Your new phone system is in the cloud. Since much of your business software is also in the cloud, that makes it easy to integrate traditional phone applications and traditional business software applications.

Phone, or shall we say voice, features including call recording, call forwarding, call routing, teleconferencing, Inclusion of smartphones into the company phone system, and inclusion of work-from-home employees into the company phone system.

But that’s just the start of what can be done. The unification of voice, video and devices means that you are interconnected wherever you are and whatever device you are working from. You don’t have to be near your desk to make or receive calls and you can share documents or collaborate on applications as well as have conversations.

Expanding into Contact Center as a Service
UCaaS is great for interconnecting everyone within a company. Wouldn’t it be great if you could also include customers? That’s been the function of the call center, now renamed contact center. CCaaS supports incoming customer service and outgoing customer marketing.

You still get as many phone sets as you need, but they’re on the network connected to the cloud and not a room full of equipment down the hall. Instead of buying and maintaining all that equipment, you subscribe to the CCaaS system. You’ll get automated outbound dialing, interactive voice response for customer self-service, automatic contact distribution, analytics and other features that have traditionally been part of call center operations.

In addition, CCaaS is omnichannel in that is can communicate with your customers through voice, SMS, video, web sites and social media. Chatbots and virtual agents can handle routine inquiries so that your employees can concentrate on the more difficult issues.

Benefits of Service in the Cloud
With cloud communications as a service, you no longer have to budget large capital outlays for massive amounts of equipment only to have to replace that same equipment years down the road. You are not bothered with having to install constant fixes and upgrades or scheduling time for a vendor to come and service your system. It’s all being done invisibly within the cloud operation. You get the latest features all kept up to date and with enough hardware to run everything. You simply subscribe for as much service as you need when you need it. As your business grows, your cloud service can expand as needed.

You have a choice in how you connect to the cloud. Some companies, especially smaller ones, simply use an Internet service with Direct Internet Access or SD WAN as the most reliable options. For even better performance and reliability a private line direct cloud connection makes the cloud seem part of your facility… as it should.

Enterprise VoIP Moves to the Cloud

by: John Shepler

Enterprise VoIP has been replacing switched circuit analog telephone business systems for decades. PBX systems transformed into IP PBX, but they were still premises based hardware and software. Now those telecom rooms are emptying as business VoIP moves to the cloud and transforms into Unified Communications.

What’s Cloud Got To Do With It?
Businesses started installing their own phone switching equipment when half a dozen buttons on a desk phone weren’t enough anymore. PBX actually stands for Private Branch Exchange. It mimics the phone company central office but sized just for your company. Even so, that can mean hundreds or thousands of people and phones. PBX systems that can handle this amount of traffic often require their own dedicated staff.

The impetus to move to the cloud centers around clearing out all that equipment and the staff to keep it updated and running smoothly. However, it’s not magic. The common joke about the cloud is that there really is no cloud, it’s just somebody else’s computer. That’s about it. Only cloud providers have huge facilities with huge staffs for economy of scale. You not only get away from the hassle of running a phone system, you can likely save money in the process.

New Capability and No Investment Required
One problem with in-house technology is that it’s easy to outgrow and it goes obsolete really fast. You avoid both issues with cloud services. A decent size cloud can handle as much expansion as you can think of. Software updates are routinely handled by the provider. Most PBX functions are now in software anyway. That means that adding or changing features doesn’t require junking racks full of perfectly good equipment. It’s a simple download to what is likely a virtual server.

Telephone calls are getting to be just one of many functions that companies want in their “phone” system. The old standard desk phone has to easily integrate with mobile smartphones where a lot of the conversations are taking place. Then there is text messaging, email and video conferencing. This is how business people communicate these days. The voice call is just one option. With IP telephony, the concept of voice as an application has been realized. What’s more, you may want to have multiple types of communication going on at the same time. That’s Unified Communications and cloud providers offer it under the name Unified Communications as a Service or UCaaS.

Special Needs of Call Centers
Many businesses find it advantageous to have their own in-house call center rather than outsourcing that function. With managed cloud services this is easily realized. You can add features such as an automated receptionist, call recording, automatic call distribution, interactive voice responses, call queues, skills-based routing, dedicated phone numbers, integration with CRM systems and reporting & metrics.

The beauty of cloud based call centers is that they don’t much care where the employees are located. None of your people will be sitting in the cloud data center anyway. This means that you can easily add remote workers and contractors to your team. They just let the system know when they are available and they’ll start getting assignments until they indicate they are unavailable.

What It Takes to Connect To the Cloud
You need to take special care in connecting your business and your people to the cloud if you want top notch performance. The Internet can be a bit dicey at the worst possible time, so you want the best connections possible. From your home office and remote offices, if possible, dedicated lines or SIP Trunks are best. Just avoid the Internet all together. Home workers may not even have that option or it can be too expensive for one worker locations, so the most reliable high speed broadband available is highly desirable. New SDN or Software Defined Networks make it easy to combine several broadband connection to make one faster and more reliable Internet connection. That can be the difference between distorted and interrupted calls and smooth seamless connections.

Are you getting frustrated with an under-performing phone system or feel you are missing out on productivity by not having the latest UCaaS features? You have many options available and complementary expert consulting to help you pick the most appropriate for your organization. Find out what Enterprise VoIP, Call Center and UCaaS services are available to you now, quickly and easily.

SIP vs PRI Pros and Cons for Business PBX

Business telephone lines have gone through several transformations. What started out as analog landlines evolved into digital T1 CAS trunks, then ISDN PRI, and finally SIP packet based network connections. Amazingly, all of these technologies are still available. We’ll take a closer look into the two most popular configurations used in multi-line PBX business phone systems.

The Primary Rate Interface
ISDN PRI is short for the mouthful of an expression that is Integrated Services Digital Network Primary Rate Interface. Often the shorthand PRI or ISDN PRI is used for obvious reasons.

ISDN PRI is a standard telecom service that is based on the earlier T1 line specification. T1 got its start as a means of consolidating 24 pairs of twisted wire phone lines into 2 pair to save the expense of long distance cabling and overloading of telephone poles. This was accomplished by digitally multiplexing the 24 separate channels so that they were all transported together on a single 1.5 Mbps digital signal. An additional advantage of going digital was the reduction of noise and crosstalk on long distance phone calls.

A major benefit of the T1 specification is that existing phone company infrastructure can be reused, including wire landlines and microwave relays. High frequency digital signals degrade over distance fairly quickly, so regenerative repeaters were added to the lines to build the signal back up. With this arrangement, T1 could be offered over long distances to serve virtually all of the customers who were using the old analog phone lines.

One issue with T1 was that if each of the 24 channels carried only the audio telephone conversations, other wiring would have to be provided for signaling. A better solution was to multiplex signal bits into the data stream by robbing a bit here and a bit there in each of the channels. This degraded the audio very slightly and allowed the T1 CAS (Channel Associated Signaling) system to be self-contained.

Additional features, such as caller ID, were introduced by the phone companies and desired for business phones and especially call centers. This is where PRI comes in. The same basic T1 line organization was kept, except that only 23 channels were assigned as individual telephone lines. One complete channel was assigned to handle all of the signaling, data and other background services.

Most PBX systems today have interface cards where you directly plug-in a ISDN PRI cable and have 23 phone lines (or as many as you have ordered) at your command. If you need more than 23 lines, you plug in additional PRIs to add more channels.

Is there a Secondary Rate Interface?
No, but there is a related standard called BRI or Basic Rate Interface. The phone companies thought this would catch on as a two phone line system or higher speed dial-up modem service. By the time it was heavily deployed, computer communications had moved on to broadband and BRI never caught on. It has been popular for radio station broadcasts and remote announcing, such as voice over artists, because it can carry high quality audio signals. Recently, this service has been replaced by broadband Internet and is very difficult to find anymore.

What is SIP and How Does It Compare to PRI?
SIP is Session Initiation Protocol. It is a technology competitor to PRI. SIP is really a standard for transmitting VoIP or Voice or Internet Protocol phone calls over networks typically shared with other computing devices.

As you probably suspect, SIP is a packet based protocol versus the channel based protocol used by ISDN and T1. In channelized systems, a complete voice channel is assigned to a phone call for as long as the call is in progress. If no one is talking, the line just sits there idle. There is no sharing of facilities. In VoIP telephony, the conversation is broken up into small packets that are routed on the network to their destination. Many conversations can be on a network at the same time along with file transfers, print jobs and everything else digital. If there is a pause in one conversation, no packets are sent to the network for that channel only.

As you can see, VoIP is more efficient at sharing the network facilities. It comes at a cost though. Sometimes everybody wants to talk or send data at the same time. Unless the network is carefully designed, it can become flooded with too many packets to handle and things back up. This network congestion causes delays in transfer that breaks up phone conversations. Any packets lost will also distort the conversation.

Network Considerations for SIP
Careful network engineering is necessary to ensure that the sensitive voice packets are transferred without delay or corruption. Usually, these data streams are given a priority using Class of Service mechanisms within the network.

A network line dedicated to SIP is called a SIP trunk. This is the equivalent of an ISDN PRI line. Any digital line capable of carrying Ethernet packets can be a dedicated SIP trunk, although T1 lines, DS3 bandwidth and Carrier Ethernet services are often used for SIP. By giving the SIP phone conversations their own line, there is no interference from other data packets. SIP trunks are most often used to connect business and call center PBX systems directly to phone service providers. Like PRI, most PBX systems have network interface cards that plug directly into a SIP trunk.

SIP vs PRI
One protocol isn’t necessarily more appropriate than the other. It depends on the application. Most PBX systems can be set up to connect to SIP trunks or PRI trunks regardless of whether the phone sets themselves are analog handsets or VoIP phones. SIP trunks are particularly useful with newer Unified Communications or Unified Communications as a Service (UCaaS) systems that integrate computers, desk sets video conferencing and mobile phones into a single interoperable system. In these systems everything is in packet format and running on a single network.

Which is Right For You?
The best choice in telephone trunks is the one that works best with the system you have or the system you desire, and at the lowest cost for the performance you need. Prices of both PRI and SIP have fallen dramatically over the last few years, so you owe it to yourself to see what telephone trunk line options are available for your business needs.

MPLS and Cloud Banish The PBX Monster For Good

By: John Shepler

Are you aware that you no longer have to deal with high investment, maintenance costs, staffing and vendor squabbles for your business telecommunication needs? Two technologies have emerged to make those frustrations a thing of the past for all size businesses. They are cloud hosted telephony and MPLS (Multi-Protocol Label Switching) networks. Both technologies are valuable in their own right. In combination, they make an unbeatable solution to your voice and data requirements.

Telesphere is a best-in-class provider of cloud-based managed services and solutions for unified communications as a service (UCaaS), especially for companies with multiple locations nationwide. Let’s have a look at the problems businesses need to solve and how Telesphere goes about solving them:


As I’m sure you know, cloud hosted PBX systems have been around awhile and are touted by many vendors. But, are you aware of the extra value that a private MPLS IP network adds to the solution?

Lower end hosted VoIP depends on the public Internet to act as a trunk line between your business locations and the vendor’s facilities. This appears to be a cost advantage since most companies already have broadband Internet installed. Why not just piggyback the phone system on the already paid for high speed Internet connection?

This does work to a degree, especially for the smallest most cost sensitive businesses. The Internet can easily handle voice, data and video simultaneously. Performance is another matter. The lack of resource control and quality of service mechanisms mean that you get what you get and that always isn’t the highest quality your employees and customers have come to expect.

A private MPLS network is engineered to handle the traffic from many customers simultaneously while guaranteeing the bandwidth, latency, jitter and packet loss characteristics you would enjoy from private lines, at a considerable cost savings. Telesphere owns and operates the largest nationwide MPLS IP network of the pure play cloud communications providers. This means that you have one vendor for delivery of your voice, data and Internet services and a system that is set up for high quality, high performance 24/7.

Do you recognize yourself as one of those frustrated users of business communications who have to deal with vendors pointing fingers at each other when things go wrong and that nagging feeling that you are paying too much for too little? It’s time to take a closer look at cloud based unified communications services to better meet your needs.
