Hi all, Can anyone tell me please about which function should I use to reply ACK to PSTN gateway after receiving a REINVITE?
A SIP proxy does not send ACK by itself. The SIP proxy will forward the reINVITE to the SIP client. Then, the SIP client should send back 200 OK which will be forwarded by the proxy to the gateway. Then, the gateway will send ACK and the proxy will forward it to the SIP client.
