10 sec call setup delay on H.323 gateway

[nalonsoamerex]

Hey guys. I'm having an issue with an H.323 gateway and long call-setup delay. It is taking around 10 seconds from the last digit input to the time it dials out. The calls are being handed to a Call Manager for processing to the PSTN. I've checked everything and can't find where I can minimize the delay. Any suggestions?

Thanks in advance.

first thing to always check is dial plan overlapping, probably you have something in there that causes this to expect more digits

if still no avail modify the T_302 timer

This is my dial-peer voip session to hand call to CCM. There is this one and the another one with preference 2 for the subscriber.

dial-peer voice 10 voip

preference 1

destination-pattern 9T

voice-class codec 100

voice-class h323 1

session target ipv4:##.##.##.##

dtmf-relay h245-alphanumeric

fax-relay ecm disable

fax protocol pass-through g711ulaw

ip qos dscp cs5 media

no vad

From the call manager it looks good. If I dial the same numbers over the cisco phones they dial out immediatly. What gives?

I figured it out. The destination pattern 9T is not specific enough and it was waiting for more digit inputs. I changed it to 9[1].......... and 9[2-9]......... and it's all good now.

Thanks for your help.

You can also set the interdigit time out under the telephony services.
