I have an issue at the moment with users experiencing noticable delay between calls connecting and both user being able to have two way voice. The H323 gateway has connectivity to the LAN, WAN and the PSTN and therefore has POT and VOIP dial peers to connect to the PSTN and to push calls to the CCM. This issue only affects the PSTN calls inbound to the site and not outbound. Any ideas?
Subset of config
interface Serial0/1/0:15
no ip address
encapsulation hdlc
isdn switch-type primary-net5
isdn incoming-voice voice
no cdp enable
controller E1 0/1/0
pri-group timeslots 1-8,16
dial-peer voice 1 pots
tone ringback alert-no-PI
preference 1
destination-pattern 9T
progress_ind alert enable 8
incoming called-number .
direct-inward-dial
port 0/1/0:15

Add this line to your voip dial-peers:
progress_ind setup enable 3

It is because of interdigit timeout. 'T' sing means everything before timeout, so use '.' and specify number of digits called.
You should do more specific dial-peers for outside prefixes. Dummy example:
# local calls:
dial-peer voice 1 pots
tone ringback alert-no-PI
preference 1
destination-pattern 91........
progress_ind alert enable 8
incoming called-number .
direct-inward-dial
port 0/1/0:15
# international calls:
dial-peer voice 2 pots
tone ringback alert-no-PI
preference 1
destination-pattern 90T
progress_ind alert enable 8
incoming called-number .
direct-inward-dial
port 0/1/0:15

Hi thanks for the information. I am taking a look, but would this resolution affect calls inbound to the PSTN line because the interdigit timer wouldnt be a factor then would it, and I dont have the issue outbound?

so, what is yours voip dial-peer with CCM numbers?
here's dial-peer to CCM example:
dial-peer voice 2 voip
destination-pattern 93456.
session-target ipv4:172.16.10.10
10-16-2007 12:51 AM
We have one setup to go to each of the CCM's
dial-peer voice 100 voip
tone ringback alert-no-PI
preference 1
destination-pattern 0164..
progress_ind alert enable 8
translate-outgoing calling 1
modem passthrough nse codec g711ulaw
voice-class codec 1
voice-class h323 1
session target ipv4:192.168.8.2
dtmf-relay h245-alphanumeric
fax rate disable
ip qos dscp af11 signaling
no vad
!
dial-peer voice 101 voip
tone ringback alert-no-PI
preference 2
destination-pattern 0164..
progress_ind alert enable 8
translate-outgoing calling 1
