SIP Trunks: Overview
The primary benefit of SIP Trunking:
Traditionally, business phone systems were powered by PRI’s made up of 23 channels. No more, no less. You had to buy 23 at a time. SIP trunks can be purchased one at a time, allowing your business to scale as demand dictates. The dramatic cost savings, coupled with voice quality and reliability that equals or even surpasses traditional phone providers is making SIP trunks the logical choice.
What is a business SIP Trunk?
Simply put, a SIP Trunk is a single voice call, routed over your Internet connection. SIP Trunks use your Internet connection to bring voice services of tomorrow to your clients today. Trunks are purchased according to the number of anticipated simultaneous calls in an enterprise. If you find you need more call capacity, you can simply add trunks as needed. SIP Trunking is your conduit to a converged IP world.

How SIP Trunks Work at Ideacom WCF:
SIP blends connections for both data and voice into a single line. By serving as a converter between a legacy phone system and a company’s Internet connection, a SIP-trunking device allows the data network to carry voice traffic. Features typically include local and long-distance calling, E911, directory listing and caller ID, all of which integrate into a company’s existing phone system.
SIP trunking consists of three primary components. These include:
IP PBX: An IP-based PBX communicates with all endpoints over an IP network. It also switches calls between VoIP users on local lines while allowing all users to share a number of external phone lines. The typical IP PBX can additionally switch calls between a VoIP user and a traditional-telephone user, or between two traditional-telephone users in the same way that a conventional PBX does.
Our Role: The role of SimpleSignal is to ensure connectivity to the PSTN from an IP network for mobile and fixed communication devices. It also transports IP communications across a private IP network or public Internet.
The IAD (internet access device) : This device facilitates connectivity between an enterprise IP network, the PSTN and SimpleSignal's network.
Note that Ideacom WCF will typically include SIP trunking as an element of an IP-phone-system package; it will only be separated into hybrid solutions when there is a need to maintain some locations on a traditional TDM (time-division multiplexing) system, which will connect to the overall IP infrastructure through various border elements and an SIP-trunking service.
