Hi all, I'd like to know if there are SIP messages exchange to maintain the session between two UA (message such as "Hello, I'am still here" / "Hello, I'am still here too" while RTP conversation is established and lasts a longtime.
The context: I have to differentiate an INVITE with a BYE which arrives one hour after an INVITE (so a conversation that lasts one hour) and an INVITE with no BYE ... (packet lost or another problem ...)
