Hello,

two options coming in my mind:

1) use dialog module and enable keepalive within the dialog

2) if you use an rtp relay (for nat traversal, etc), then thee were some patches that rtpproxy is sending an xmlrpc command to kamailio, which via dialog module can send a bye. Not sure what is the current status with that patch or if rtpengine has anything similar.

Cheers,
Daniel

Hi all,

I am working in basic call. I got common cause that opposite side (callee) lost connection and caller still hangging in the call. Is there any message to server to caller in this case?

Thanks,

Nhan
