Dear All
Maybe, i find the reason
It's because the standards, chan_ss7 doesn't send address completed
after getting iam but then after if the extension starts ringing,
chan_ss7 is sending alerting and here our provider cancels the call,
because security reasons, just because this behaviour is not followed by
ITU standards.
We have to work on this issue,
Does any body know how to debug the fully but only ISUP signalling on
chan_ss7?
BR

Meaning immediate ANM or some SSP just responding without full trunk
processing in siganlling. Not trying to mix bearer and signalling here,
but here's the point. Programmers.

Almost sounds like a ISUP timeout issue, or just some timeout issue.
Have we tryied anthing with ISUP CPG???
What's you're post dial delay, PDD. It's usually between IAM and ACM,
buit could be satified with CPG. I'm thinking this because if ANM does
the job....

Works of coarse. Try putting Ringing() before Dial() or
check your SIP route. Strange that REL is received on your
SS7 - not sure, but looks like your telco side is releasing
call. Put here more messages and your dialplan.
