.323 gateway and CUCM call hand up delay and call s

[ausjustin]

I've got a very vexing issue.  I converted a router over from MGCP to h.323.  IOS Advanced IP Services 152.4M6  With MGCP to H323

there was never an issue :

1.       Intermittent call drop outs

2.       Inbound calls call hang up / call termination / end call delay issue around 30 second delay 

Thanks

Hi Justin.

Thanks for the configuration.

Can you also please send a show controller E1 and a debug isdn q931 during an incoming call with a termination delay?

Thanks

Hi Justin.

From this debug I can see that the call has been disconnected immediately.

Can you confirm it?

please also add these to commands in your config

voice call disc-pi-off

voice call convert-discpi-to-prog

Let me know

Regards

Carlo

[ausjustin]

I already add on  voice call disc-pi-off .

but what's the "voice call convert-discpi-to-prog"  for ? 

[ausjustin]

and also do you think we remove the " service mcid" will help ?

dial-peer voice 1 pots
 description **** Inbound Calls****
 service mcid
 incoming called-number .
 direct-inward-dial
 port 0/0/0:15

[Carlo Poggiarelli]

HI Justin

That could help

Regarding voice call convert-discpi-to-prog is to change the diconnect message to progress in order to try to send the call status to the CUCM when a disconnect arrives from PSTN

HTH

Carlo

[ausjustin]

thanks a lot . 

and also maybe I will try change this above timer  "param mcid-release-timer" to 10 seconds instead of 30seconds and then see whether now the calls disconnect after 10seconds, which confirms that the issue is with MCID.

[Carlo Poggiarelli]

Yes.

Also try that and pleas let me know

Regards

Carlo
