SIP Trunks for the Avaya IP Office, NEC SV8100 … What are SIP Trunks anyway and why Digitcom?

Published on: February 07, 2013

If your business currently has an on-premise phone system but doesn’t allow for some of the advanced features like area code consolidation, fail over, remote call forwarding, Digitcom’s new SIP trunking solution allows you to take advantage of such features while reducing the disruption of upgrading and lowering associated infrastructure investment costs.

Digitcom has been selling SIP trunks for a few years, and we have done many installs with the Avaya IP Office phone system specifically. In many instances the SIP trunk vendor struggles with the nuances of making their SIP trunks work with the various versions of the Avaya IP Office. As a result, Digitcom, as part of our Hosted PBX network build, which we launched a few months ago, has also designed a very elegant SIP trunk solution which we’ve tested with all versions of IP Office from R6 and higher. We designed it, built it, support it, and understand how to deliver a successful end to end solution with no finger pointing.

But what are SIP Trunks, and why Digitcom?

SIP (Session Initiation Protocol) trunking is an alternate mechanism used to connect phone lines into an organization’s business telephone system, and it is emerging as a viable alternative to legacy PRI and traditional analog lines. Simply put, a SIP trunk is essentially a telephone line, similar to the analog line, but is delivered into the business phone system through a broadband or Ethernet connection.

The advantages of a SIP trunk is the flexibility it provides, allowing businesses of all sizes access to cutting edge communications features.

Multiple area codes route to a single location: Let’s say, for example, that you want the area code 604, 514, and 613 all to route to your Toronto office phone system; with TDM (PRI and analog lines) this would be very difficult to deliver, while SIP trunking offers it standard.

SIP’s fail-over features: Because the SIP phone line itself arrives on a data circuit, there is considerably more flexibility with the routing of in-bound calls, meaning that it’s very easy for SIP to fail over to an alternate location. Let’s say, for instance, that your Toronto phone system is down, can recognize the data circuit isn’t reaching its desired end point destination and we will automatically re-route the call path to an alternate data line.

Absolute resilience: SIP Trunking can be used to provide a solution with guaranteed 100% up-time. In the unlikely event that all of your SIP trunking services are unavailable at one site, you can instantly re-route your inbound calls to any destination by redirecting calls to a number of your choice.

SIP Trunk Rationalization: Does your business have multiple sites? Do you have a PRI connection into an individual PBX at each site? By using SIP trunking, you can reduce the number of PRI connections that your business requires and also reduce the maintenance costs on all of your various PBXs. At the remote sites you are left with just the cost of an IP connection and the handsets that you need and you can then pull all the telephony traffic back into your centralized PBX.

Not only that, but SIP trunking also increases your resilience because you can build an automatic fail over system into your communications strategy for lines and calls, should your main site go down. With SIP trunking you can instantly centralize and distribute the calls somewhere else, to another site or to home workers for example.

Remote Call Forwarding: Number flexibility with SIP Trunking means that you can keep your existing number, even when moving out of the area, saving you costs on printed company literature and stationery whilst maintaining the perception that you still have a presence in the area you’ve moved from.

We can easily transfer your old or existing numbers to Digitcom so that you can avoid expensive Remote Call Forwarding (RCF) charges.

If your business currently has an on-premise phone system but you’re missing out on the latest state-of-the-art unified communication features, SIP trunking is your affordable gateway to the future.
