Very newbie here. Even I may not know what I'm talking about. Please be patience, thank you :)

I had auto dialer and I have problem with unreachable numbers.

So I wish if I call busy, unavailable, ringing but not answering numbers, system will hangup before the voice mail active.

After some googling I found a sip proxy may solve my problem. 

I setup kamailio and manage to work with an example edge proxy setup.

Then what ?

My wish is, after the number dialed, start to filter every sip message, then let say if I do not get 183 session in progress in 10 seconds, or get a 10 trying in 10 seconds hangup line.

Which module should I look after.

My Best Regards.
