What are the benefits of SIP trunking over T1 trunking?

In this expert response, learn why SIP trunking is preferable over older implementations.

What are the benefits of SIP trunking over T1 trunking? What is needed on a PBX to support it?
SIP trunking can eliminate the need to have a traditional PSTN gateway. Basically it takes all the data, voice and media and passes it through the carrier systems as IP traffic without doing the conversions first. They also can improve the speed of the calls by allowing the packets to travel as data until the final destination when you need traditional analog at the other end. This can be a significant savings over the older implementations that required gateways for analog signals.
