[Freeswitch-users] IVR Bridged Call Dropping after 2 rings

[John Carpenter]

I have spoken to my SIP trunk supplier and they say they have a timeout
of 10 seconds on their system, so if no signalling or RTP media it
disconnects. So question is now how can I get FS to send some signalling
or RTP messages back to SIP trunk while my IVR is dialling an extension.

regards, John Carpenter
