[Asterisk-Dev] HELP: BYE-request not sent to SIP-peer

[Roland Zagler]

Hello,

When i have a "Hangup" in my dialplan (extensions.conf) the RFC says to
terminate the session is to send a BYE request to UA. After tracing the
traffic on port 5060 UDP i recognized that my asterisk is NOT sending a
BYE request to it's peer, so the peer doen't know to end the session and
continues to send RTP packages to me. Does anyone know how to fix this?

Here's the complete trace from ngrep(make call, speak for 5 seconds,
hangup): UDP port 5060 in all directions
