In the configuration tree> system configuration>Telephony tab>Look under dial delay time and try lowering that number.

Create outside call short codes without (;) in them, such as instead of 91N;    Make it 91xxxxxxxxxx

The time delay is the IPO sending the digits as dtmf to line

I would suggest adjusting some ot the settings in the Analoge section of the line

DTMF mark & space look like they could be lowered also the intermediate digit pause could probably be reduced.

Here are the result from each of the suggestions:

Reduced dial time delay from 4000 to 2000: No effect.

Removed ; from shortcodes: The call never completes.  The phone just sits there indefinately with the dialed digits on the display.

Reduced DTMF mark, space & pause: No effect.  I was very hopeful that this one was going to do the trick since the default pause time is 500ms.  I cut each parameter in half but it didn't seem to have an effect.

It's still taking about 12 seconds after the last digit is dialed before you hear the first ring.  Is this normal?

Any other suggestions?

I am now using a pause time of 100 Ms which seems to work ok, call setup is only a couple of seconds.
My next sugesstion would be to put a test butt accross the line & listen to the digits beeing dialed.
any time taken to connect after the last digit is down to your network provider

Thanks!

I'll give it a try later tonight.  I didn't know how low I could go without making the dial process unreliable.
