Long PDD in cisco voice gateway

[daneth.mean]

Dear All,

I have same network scenario as below:

Mobile phone (Originate PSTN) -------------------> AS5400XM( H323)-------------------> (H323) Gateway ( Terminate GW )---------> client Mobile phone.

I have problem as below

1. how to check Post dial delay between Originate PSTN to AS5400XM?

2. I have sent call to terminate gatway with H323 protocol and is there any command to check PDD in AS5400 to

Terminate GW? How to solve long PDD in such case in each segment?

Best Regards

Dan

With a correct configuration, there is zero PDD.

'debug voip ccapi inout' will show u realtime events and can point to where the delay is coming from.

Hi Dan

If the call is originated from PSTN, just check with your PSTN provider and identify the Interdigit PDD timer and try to reduce it. Also when the Dial-pattern is configured correctly at the PSTN then the PDD is minimal. Make sure your provider has configured it properly.

PDD will be longer as a call that is completely dialed has to wait several seconds for additional digits to be sure it has all the digits.

Thanks.
