Hello,
During three-way handshake (SIP call setup - INVITE-200 OK - ACK) and
before generating or sending the final 200 OK call, is there a way to
confirm the caller is still available (no network issue)?
I want to detect broken connections (ex. the uac uses 3G network) before
generating/sending/forwarding the final 200 OK.
Thanks.
Regards
Abdoul
