SIP Trunk is a voice call CONNECTION placed over your Internet connection. This VoIP “trunk” (or phone line) connects to a PROVIDER who routes your calls through their gateway and usually has very reasonably lower rates on long distance calls, international calls and in-bound toll free calls.

Additionally, SIP trunks can carry instant messages, multimedia conferences, user presence information, and Enhanced 9-1-1 (E9-1-1) emergency calls.

• Eliminate BRI and PRI subscription fees because SIP trunk connected directly to an Internet telephony service provider.
• Eliminate IP-PSTN gateways (or even your entire PBX)
• Low cost long distance calls, international calls, etc.
• Expansion of lines is dependent on bandwidth, which can easily be INCREASED if needed. It means that with SIP trunking you don’t need to buy lines in blocks of 24 or 32. Instead, you can buy the bandwidth you need in smaller increments.
