how to shorten H323 call setup time?

The call setup time is a little longger, we tried serveral methods: using terminator; adjust interdigit timeout; but didn't improve.

The signaling between 5350 and PBX is pri, we use RAS. We must use '.T' because of the variable length and too many sites.

I know the setup time of H323 is little longer then old PSTN and SIP. But I want to know if there are any other methods to improve.

Re: how to shorten H323 call setup time?

Using T1 PRI will reduce the call setup time. I think you can speed up your call set up process by using H.245 Fast Connect.

Heres the URL for the same:
