[OpenSIPS-Users] calls have max call duration

[M.Khaled W Chehab]

Hi,

 

Please  that the problem still exists, now  I can find calls having  190 or 188 seconds since the value at /proc/sys/net/ipv4/netfilter/ip_conntrack_udp_timeout_stream is    180 

,since it should be 0 seconds,

Any idea to drop  the accounting if the UA send a  cancel as  the  below scenario .

 

Regards

Your opensips config is pretty messed up and hard to read. So, while i try to read it to find the problem, as a workaround you should set RTP timeouts in your mediaproxy configuration file (i.e. config.ini), e.g.

 

stream_timeout = 30

on_hold_timeout = 1800

This will result in automatic call hangup if there is no media for at least 30 seconds. This will reduce wrong billing problem to 30 seconds, and your customer's balance will not be exhausted completely. Similarly if call is on hold for more then 30 minutes and no media is transferred during this time (not even music on hold) then call will hangup (change this timeout to whatever appropriate for you).

 

Thank you.

Dears,

 

How to drop  the call  when a cancel received from UA and a 200 OK from the trunk in the same second, note back the client cdr will be a canceled call and the trunk cdr will be 1 sec duration but on my cdr its the max daialog  timeout duration

 

I am searching for a  solution for this since two weeks as I tried all trick I know and all didn’t succeed ,

Find attached the scenario I have problem with, which you can find it at  wireshark time line (30.877027)  the Client with IP ( 74.114.101.170) sends  a cancel ,and the opensips version 1.8.2  server with IP 89.207.133.144   send the client 200 canceling and  in its terms forward the cancel to the trunk provider with IP 74.114.101.190 ,but at 31.015333 wireshark time line the trunk sends a 200 OK  then 487 request terminated  and the billing stops from the trunk provider  .

The problem is my opensips with IP 89.207.133.144 didn’t hangup the call and go for the max call duration in the dialog module .

-how to let opensips cancel the call immediately  and stop it with no billing .

Please find attached my opensips.cfg configuration file 

 

Regards
