SIP - How close active call, if destination goes down

[jaroslav.srytr]

Hi,

I use “connection trunk 26“ syntax on voice port and number 26 match with VoIP dial-peer. VoIP dial-peer uses UDP SIP as transport protocol.

All works fine, but my problem is that if destination device goes down, call (trunk) is still active and RTP is sending.

It’s possible check state of destination device and close active call if destination device is down?

Hi Paolo,

Thank you for your response, but I’m looking for automatic “connection tracker”. I need some SIP/ICMP keepalive and disconnect all calls in situation, when a destination device doesn’t response.

You can use RTP/RTCP media inactivity detection, session timeout, or options-ping. All are described in documentation.
