SIP Trunking is a single conduit pipeline for multimedia elements (voice, video and data). SIP Trunks provide a replacement for an existing ISDN connection, enabling connectivity to the PSTN using an IP connection. SIP Trunking supports the standard features of a class 4 PBX:
- DDI – inbound
- PSTN – outbound
- CLI presentation
TeleWare provides SIP Trunks from the TeleWare hosted service platform on a TeleWare-certified end-to-end network. This allows the customer's PBX to be connected through an existing data network to TeleWare’s application-rich hosted services platform which is already connected to the PSTN.
SIP Trunking offers a way to lower both capital and operating expenses for business networks. Traditionally, a company PBX is connected to the public telephone network (PSTN) via ISDN using basic rate or primary rate circuits to the PSTN.
A SIP Trunk is a line or channel based on the SIP protocol, which provides high levels of interoperability with IP devices on the market today. A SIP Trunk provides a cost efficient, high quality and reliable replacement for traditional PRI or analogue circuits.
