SIP Trunks

A Session Initiation Protocol (SIP) trunk is an easy and efficient way to connect your company's private branch exchange (PBX) telephone system to the public switched telephone network via the Internet.

A SIP trunk supports multiple concurrent phone calls on the same phone number, as well as multiple dedicated phone numbers on the same trunk. Such unparalleled flexibility can accommodate even the most complex configurations.

Popular PBX soft switches include Asterisk, 3CX and Freeswitch. Many hardware PBX'es such as Panasonic and Auerswald PBX also support SIP Trunks.

Service Availability

We offer dedicated local numbers in most large US cities and metro areas, as well as nationwide toll free numbers. DID numbers are also available in Hawaii, Puerto Rico and Canada, but for an additional charge. We can route outbound calls to the US and most international destinations.

Service Requirements

This service provides a "naked dial tone" only. To use this service, you must operate your own PBX, which is connected to the Internet and supports the SIP protocol. About 80 kbps (0.08 Mbps) of Internet bandwidth required per concurrent call (G711/ulaw), or 30 kbps with higher compression (G729, lower quality). Static IP address recommended, but not required.

This service can be used bi-directionally (inbound and outbound), or uni-directionally (inbound or outbound service only). It's your choice.
