[OpenSIPS-Users] ACK Timer

[M.Khaled W Chehab]

Please can you show me by code  the better way(ensure Cancel)  since this is a critical issue and I am relaying the cancel and after that trunk  send me more than 8 time 200 Ok  ,as is there a way to stop/hangup the call since I receive the cancel from the client 

 

2-what do you mean destination must be very quick ( since 200 oK is received  the normal reply (ACK) takes  millsec or I am wrong ?

 

 

Regards

This may work, only if you create dialog with 'B' flag, also 3 seconds look very short, destination must be very quick to ACK the call.

 

I think there is a better way to achieve this, you only need to ensure CANCEL is received at destination.


Thank you.

Hi ,

 

I face a lot of scenarios where the customer send a cancel while the  trunk send 200 OK and start the billing from its side ,so the client call will be canceled from his side and goes to the max call duration from my side and trunk side .

Si I draw this function below 

loadmodule "dialog.so"

modparam("dialog", "timeout_avp", "$avp(timeout2)")

 

if (has_totag()) {

              if ( is_method("INVITE")) {

                     $avp(timeout2) = 3; 

              } else if (is_method("ACK")) {

                     $avp(timeout2) = 3540; 

              }

 

Do this function effect on my calls or cause  any problem

 

Regards
