Cisco phones takes more than 20 sec to connect the PSTN

Dears,

I have a Cisco 2921 CME with FXO four ports, all the ports contain land lines.

Now when I try to call outbound (PSTN) it took more than 20 Seconds, so please is there any configuration we can apply on the CME to reduce this time.

Apprecite your support,

Use interdigit timeout command under telephony-service. Something like:

telephony-service

timeouts interdigit

Please rate helpful answers!

You probably have overlapping dial-peers you need to correct.  Changing the interdigit timeout will just hide the problem and may cause problems for the users.

If you dial the number and wait until it connects, then release the call and hit the redial button the call should go inmediately. If this is correct it means that you have overlapping patterns and the dial plan should be changed to avoid this problem.

Ali,

My understanding from your dial plan is that you have a variable length.

I recommend you to change the interdigit timeout to a lower value, perhaps 5 seconds or using the # sign after you finish dialing to avoid the timer.

telephony-service

timeouts interdigit

Hope this helps!
