Making Use of SIP Trunking

Integrating the IP PBX System

Integrating VoIP with Your IP PBX

One of the hallmarks of VoIP is its flexibility. It inherits this characteristic from the Internet and the IP-based systems which are at its heart. This flexibility manifest itself in the ability of businesses to utilize VoIP in different ways depending on the circumstances and their existing infrastructure. For example, it is possible for a startup with absolutely no purchased hardware to get started with VoIP almost instantly by signing up with an SIP service provider. Employees will already have their smart phones from which they can use VoIP and computers can be used with a headset and a microphone. On the other extreme we have businesses that already have a significant PBX infrastructure. So far they have been using it for intraoffice calls and they wish to extend the features and cost-saving benefits to communications to the outside world as well.

This is where SIP trunking comes in. An in-house IP PBX system is an isolated entity. It works well for calls between employees even when they are separated geographically. The whole thing runs on the Internet and an IP-based network so it's free from end to end. This translates into tremendous cost savings for the company since most communication takes place between employees in an organization. In addition, they can talk to each other in HD voice since there is no PSTN system acting as the go-between.

Extending the IP PBX

This simple PBX functionality can be expanded to integrate with the external PSTN world using a VoIP gateway. But setting up such infrastructure, configuring it, managing it and negotiating with the telecom companies isn't for everyone. An SIP vendor will be able to provide you with an "SIP trunk" that will link your IP PBX system to the PSTN network. You will also be provided with Direct Inward Dialing or DID numbers using which every person who is on your VoIP network will be reachable directly.

The SIP trunk is nothing but a pipe. The business itself has to do all the heavy lifting by configuring the VoIP system, implementing the correct protocols, maintaining the hardware and upgrading the software. A business will only choose to do this if it already has a significant investment in infrastructure that it wants to leverage. Otherwise, it really makes no sense to build such a system from scratch when there are professionals to which it can be outsourced. There are many local VoIP based Boston phone services you can contact to implement VoIP integration between your IP PBX system and the PSTN network.

Contact your ITSP to find out how to get started.
