Sigtran vs. Sip protocols explained.


In this post, we will explain Sigtran vs SIP. Sigtran uses an IP network for message exchange, and SIP also uses an IP network. But there are significant differences. The Sigtran is ss7 messages over the IP network, while SIP is an entirely different protocol used in VoIP. 

Any roaming or message application written on top of the ss7 stack is the same whether the network is ss7 or Sigtran. At the same time, a SIP application is different.

For media or voice, Sigtran uses  E1/T1 channels for transmission. While in SIP, the voice or media use IP-based protocols, e.g., RTP.

Sigtran has ss7 adaptation layers, while SIP doesn’t have any adaptation layers.
