What is SIP trunking?

Voice Over IP (VoIP) is used in Session Initiation Protocol (SIP) trunking to facilitate the connection between an enterprise Private Branch Exchange or PBX to the Internet.

SIP is a standard for initiating multimedia sessions and trunking is the process of connecting several nodes in a communication system which can carry many signals at a time.

 

Advantages of SIP Trunking

SIP Trunking reduces the costly BRIs (Basic Rate Interfaces) and PRIs (Primary Rate Interfaces) subscriptions.

For business SIP trunking provides ISDN line rationalization and reduces the enterprise PBX needed to maintain.

No extra PSTN (Public Switched Telephony Network) required as the enterprise grows in size.

Unlike traditional POTs and T1/PRI that requires planning for peak at all the time, SIP trunking provides scalability as per needed. The enterprises and customers pay only for what they use and can enable excess capacity if needed.

SIP trunking provides Flexible termination of calls to preferred providers; calls to anywhere worldwide can be made for the cost of a local one .

 

Why focus on call centres?

Carriers don’t like to provide VoIP to the call centres because of the aggressive and predictive calls generated through automated dialers. This causes high strain on the carrier’s equipment and networks.

 

What equipment does the service work with?

SIP is a IETF standard, hence straight forward to deploy. According to each manufacture/developer deployment can differ slightly. VoIPberry’s service has been integrated with various latest and high end platforms like Avaya and Cisco to provide best performance to its customers.

 

What if my dialer / PBX does not support SIP?

If your PBX doesn’t support SIP then a SIP gateway can be placed in between your PBX and the VOIPBERRY service to make it SIP enables. Most of the telephony manufacturers sell SIP gateways which converts TDM to SIP.
