How to release the channel of finished conversation

There is scenario:

  1. Asterisk opens SIP channel toward A (PSTN endpoint, NOT ISDN) thru my sip provider automatically by .call file in /var/spool/asterisk/outgoing
  2. A dials by DISA to B (PSTN endpoint, NOT ISDN)
  3. Starts conversation A,B
  4. A on hook , B on hook
  5. In point of view of the PSTN the A and the B are receivers of the call, so channels toward A and B are still open 90seconds more (and my sip provider charge me 90s. more twice).
    How to reduce this time (90sec.) to 5-10sec? I made some experiments with WaitForSilence( ) , but without success.

Thanks in advance!
Ps. Sorry about my English!

Nobody can answer??

Well lets see

No Debug of a call…
No example of the call file…
No dialplan …

So suppling Nothing , you expected a problem to be solved…

Sorry but the crystal ball is broken and noboby has proved that ESP realy works :wink:

In my opinion the question is principle, but these are the files and traces that you mentioned, if you think it will help:

Debug of a call

exten => 1,1,system(cp /var/spool/asterisk/ /var/spool/asterisk/outgoing/)

exten => _X.,1,Dial(SIP/${EXTEN}@ch3

And here is my experiment with “WaitForSilenceâ€

goto your zapata.conf and add the following.

busydetect = yes

I hope it works for you.


Are you sure about this? I don’t have any hardware cards on this PC and in my opinion the zapta driver is useless here. All my channels are SIP.

Hi, I have rtptimeout=60 in sip.conf. Maybe try a search for rtptimeout= to get more info or get more info here: … rtptimeout

Thank you commotalk. This sounds interesting. I will try.
