International calls are not working

[Syed]

Dear All,

Quick help, please.

International calls are not working for few users.

I have checked partition & css, and it was working fine till yesterday.

Message from the phone: You call cannot be completed as dialed.

Call Flow:

IP phone – CUCM – SIP Trunk – (SBC Could)

Please advice

Thank you in advance

Regards,

for your information: Calls are working when dialed enbloc but not digit by digit

Hi Syed,

What is the route pattern used for international calls. Check for any overlapping route patterns in the system.

It was working till yesterday, and there is no change made in the network.

Route Pattern: 9.00! & 9.001#  these are the only patterns

[Syed]

I suspect call manager service is hung, what do you say?

[Syed]

Hello Everyone,

This is now fixed.

I do not know how but urgent priority was checked on the pattern which was causing problem.

Thank you so very much for your help & support.

Appreciate it... Cheers

If you're only looking at route patterns to discard overlapping, you're not doing this right.

You need to review your WHOLE dial plan, and look not only for DN/patterns that start with 9, but also anything that has wildcards and could be a match.

Hi Syed,

If call are working when dialled enbloc, there are more chances that you are hitting a pattern while dialing digit by digit which is causing issue.

You can check overlapping pattern in DNA easily.

You can find the same information in CCM traces make sure you Set Digit Analysis Complexity" to "TranslationAndAlternatePatternAnalysis"Under Call manager service parameters, also it has to be dont on all server as it is a System parameter not Clusterwide parameter.

Digit Analysis Complexity:	This parameter specifies the amount of digit analysis information that CCM trace files will provide. Cisco CallManager offers two digit analysis modes: StandardAnalysis, which provides detail about the final matched pattern without the translation pattern and alternate matches detail, and TranslationAndAlternatePatternAnalysis, which provides information about the translation pattern and the alternate matches while finding a match for a pattern.
	This is a required field.
	Default:  StandardAnalysis
