Cisco IPT Call Manager

[thewizard1972]

has anyone come across this before and what was the fix

If i dial any number from my phone there is a 5 second delay before it is actually dialed but if i press redial it works straight away as you'd expect.

I have reboot call manager and has not fixed the problem

thanks

I would look at "interdigit timeout" settings... Google it and see what you find...

this is set to 7ms but the strange thing is that if you dial a number using speed dials or redial it is instant hut dialing a number has a delay.This is the same of internal & external numbers

hmm... this is strange.. (This is Call Manager 3..)

Look at this..

"CSCdu47183
The delay before dialing timer for groundstart CAS is always set to 80-90 ms.

Workaround: No need exists to set this timer. It is always set to use 80-90 ms in the hardware to meet the EIA464 requirement."

Honestly, I am not sure.. Will have to wait for the experts.. I looked at Cisco's troubleshooting guide but found nothing.. Sorry

The 5 second delay is interdigit timeout. The reason that you do not get that on a redial is because the call has been dialed before and ignores the interdigit timer.

You said that the timer is 7ms. One second is the lowest setting in call manager for that timer. if it was 7ms you would not be able to complete a call (unless you can press 2 digits on the dial pad in 7ms).

So your issue is this:
You have route patterns/internal dial plan that overlap and the system waits 5 seconds to make sure you are not going to add more digits. After that it releases the call matching the closest RP or DN. You need to fix your RP overlap and the delay will go away.

BTW what type of trunks to the PSTN? What range are your extensions in and what do you dial for outbound access?

it does look like an overlap in the dial patterns, have any been added since this started to occur?

how can i check the overlap in dial patterns?
we recently added a new number range

Go into your CCM Administration page.

At the top there is a Route Plan drop down, go to the Route/Hunt, then Route Pattern.

From there you can search through your route patterns to see what you have and just see if there is anything overlapping.


Also, if you just added a new number range, what is the new range and what do you dial to access to dial outside?

For example we have 9500-9599 as one of our ext ranges, well that can make it some what difficult to use 9 as our outside dialing code, so I have it set to 8 to dial outside.
