Dear All!
In PSTN networks, it's beneficial to try to establish a connection between the caller and the callee before the full phone number digits are collected. But SIP works over the connectionless IP network, is there any benefit to use overlap signalling in a native SIP network? Are there any official standards or technical materials that documents overlap signalling in a native SIP network? Thank you very much!
