Through A Single App
Adding SIP trunks to a high-quality PBX service can drastically reduce expenses in several ways. First, you eliminate monthly charges from a service provider.
SIP trunking also reduces costs by eliminating the need for separate voice and data connections, and expands the potential for communications convergence using both voice and data together.
Because SIP trunks are virtual rather than physical, scaling and maintenance are much easier. With legacy telephony, increasing capacity requires you to purchase additional physical lines from the phone company.
SIP trunks are extremely stable, because as virtual lines they are not susceptible to local power outages resulting from weather events or equipment failure.
To understand “SIP Trunking”, you first need understand “SIP”.
SIP stands for “Session Initiation Protocol”. It is the technology used for establishing a voice communication session on a data network (e.g. over the Internet).
A SIP “session” might be a regular VoIP phone call between two participants or a multi-party conference call.
A SIP Trunk provides the same service you get from a traditional analog phone line. The difference is, instead of being a physical wire, a SIP Trunk is a “virtual” phone line which is provided by a SIP trunk provider. They use your data circuit (T1, Cable Modem, DSL, Ethernet over Copper, etc) to connect your phone system back to their network.
We provide a high quality SIP Trunking service, connecting your PBX directly into our network via a DSL or Ethernet IP connection. This allows you to receive and terminate your voice calls over the public telephone network.
SIP trunking provides a highly flexible alternative to ISDN and has been fully tested with many leading IP PBX applications such as Asterisk, Avaya, Cisco, 3CX, Freeswitch and SNOM.
