Take too long to connect to PSTN!!!

hi all,

We have 3640 T1/PRI connect to Telco, aslo have Callmanagers (1 Primary, 1 Secondary).

If I dial 9 plus 10 digits(national), it will connect fast and smooth!

If I dial 9 plus 7 digits (local), it will connect after 12 seconds (slow)!

In callmanager: we have Route Pattern "9.@", "north american numbering plan", I didnt use any route filter.

Also, I set "TimerT302_msec" to 4000

Also I configure on 3640

voice-port 1/0:23

timeouts initial 1

timeouts interdigit 4

Whatelse I should add or change to improve this problem.

Thanks a millions

Ken

You will find that you need to use route filters, without route filters call manager will wait 10 seconds after the last digit to see you you dial any other numbers. Once a caller matches any one of the route filters the call is placed without waiting for the timeout.

Hope this helps. There is lots of documentation on creating route filters on cisco's web site.

You might try building two separate route patterns instead of one generic 9.@ pattern.

For local 7 digit dialing I built a route pattern: 9.[2-9]XXXXXX

For long distance 10 digit dialing I built a route pattern: 9.1[2-9]XX[2-9]XXXXXX

For international dialing I built a route patttern: 9.011!

Create two 9.@ patterns both will have a different route filter.

The first route filter name 7-digit-dialing it will consist of area-code does not exist.

The second route filter name long-distance. It will consist of area-code-exist.
