SIP More Features At Lower Costs

Primarily, a SIP Trunk is a concurrent call routed over the IP backbone of a carrier using IP technology. SIP Trunks are used in conjunction with an IP-PBX (Private Branch Exchange) to replace traditional PRI or analog circuits and are fast becoming the standard technology that businesses use to make and receive telephone calls at a lower cost and with more features.

SIP Trunking can also be used with traditional PBX systems

Connections can be made to a PBX via analog Business Lines or PRI Services. SIP Trunking can work for Legacy PBX Systems by using an IAD (Integrated Access Device) that allows SIP Trunks to seamlessly connect with the system.

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.
SIP Trunking can blend connections for both data and voice into a single line.
The popularity of SIP Trunks is due to cost savings, increased reliability, added features and flexibility.
IP Trunking easily integrates to a SIP enabled IP-PBX.

Service Provider performs extensive interoperability testing with each PBX manufacturer before they make their service available in conjunction with their equipment.
