What is the respond of terminal, if there is no replies to its Keep alive messages ?
Namely, we are looking for possibility that T27G terminal automatically disconnect the established SIP session if there is not respond to Keep alive message from Call server. Is it for any from listed (UDP, SIP OPTION or SIP NOTIFY) implemented such respond ?
