SIP trunk services are being implemented by more and more enterprises. Companies like InnoMedia are striving to improve the technology and serve enterprises with a comprehensive line of enterprise session border controllers which also support one or multiple PRIs or primary rate interfaces. PRIs enable a digital transmission service for businesses from the telephone company.
Recently Buckeye TeleSystem has further expanded its adoption of the InnoMedia ESBC line for its SIP trunk offerings. InnoMedia is a specialist in embedded enterprise session border controller or ESBC technology.
Adam Hashi, manager of VoIP Engineering for Buckeye TeleSystem said, “Buckeye TeleSystems is successfully offering enterprises the benefits of SIP trunks regardless of whether they have IP Phones, IP PBXs or a traditional TDM PBX.”
Officials explained that SIP trunks are incrementally scalable in real time which eliminates the need to install new lines. This makes it cost effective when compared to conventional analog phone circuits.
InnoMedia’s PRI capable ESBCs enable enterprises that depend on in-house TDM PBX phone systems to leverage all the features of SIP trunking. Also they need not replace their existing PBX and telephone sets.
Service operators are now able to ensure the provision of scalable, QoS-managed SIP Trunking and hosted PBX services to business customers by using the InnoMedia ESBCs. Also enterprises that use TDM PBX can utilize the InnoMedia ESBC with PRI to benefit from a simple migration path to hosted deployments. The full end-to-end SIP trunking capability eliminates the need to install new customer premise equipment.
PRI-enabled models allow service providers to provide SIP trunks to end users with traditional PBXs using a PRI connection. It connects a company PBX to the public switched telephone network (PSTN). PRI is an ISDN dial-up service which uses four wire pairs. PRI/T1 provides 23 voice channels and one signaling channel, and PRI/E1 delivers 30 voice channels and two signaling channels.
