AAR Failure

Hi,

I have the following simple AAR scenario:

- 2 locations, 2 AAR Groups, 2 Phones;

A) Location HQ:

1. Automated alternated Routing Enable: True;

2. BRQ Enable: True;

3. Phone A(2001) Location: HQ

4. Phone A Line 2001: AAR-HQ; External Phone Mask: 408311xxxx;

5. Phone A AAR-CSS: full;

6. MGCP Gateway Location: HQ, AAR-HQ;

B) Location BR1:

1. Phone B(3001) Location: BR1

2. Phone B Line 3001: AAR-BR1; External Phone Mask: 312511xxxx;

3. Phone B AAR-CSS: full;

4. MGCP Gateway Location: BR1, CSS:AAR-BR1;

I have the following route patterns:

a) 9.1312511XXXX -- in partition PT-AAR that points to HQ Gateway; Discard PreDot Digits;

b) 9.1408311xxxx -- in partition PT-AAR that points to BR1 Gateway; Discard PreDot Digits;

Between AAR Groups I prepend "91" digits.

I restarted CCM Service, even Call Managers servers.

I configured locations BW 10 kbps.

My problem is:

I am calling Phone B(3001) from Phone A(2001) and AAR doesn't work:

Symptoms: On Phone A display I have message "Network congestion, rerouting" but called number remains "3001". The calling number is not changed so my call didn't complete.

What is your opinion about that?

Call manager version: 4.1(3).

Many Thanks,

Cristian

Re: AAR Failure

Hi,

Yes, is a new config.

I have "Automated alternate routing enable: TRUE" on CCM service parameters.

Many thanks,

Re: AAR Failure

Does AAR-CSS include PT-AAR? Is this CSS applied as the AAR CSS on the device?

Also double check the Location assigned to the GWs to make sure they have the appropriate ones.

CCM trace logs will tell you exactly what the issue is.

HTH,

Re: AAR Failure

Hi,

Yes, AAR-CSS include PT-AAR; this is applied as AAR CSS on the device. The "normal" CSS on the device is a CSS with full rights.

I will duble check the locations but I checked every step of configuration.

Could you help me please with trace? What trace level do I need for AAR? And what do I need to search in trace file? Or maybe you know a good troubleshooting document for this.

It should have been an easy task for me:-)

Many Thanks,

Cristian

Re: AAR Failure

Make sure the CM trace level is set to detailed. The only good source I ever found for analyzing CM traces is the "IP Troubleshooting" book.

HTH,

Chris
