I have a multi-site, multi-cme deployment.


CME versions 7.x


Site A: CME/CUE

Site B: CME/CUE

Site C: CME - uses Site B CUE


Among other things :), intermittently, calls are failing to VM on calls directed to Site C: but fwd to Site B:


Calling Number = 313 (Site B:)

Called Number = 777

call-forward noan *400 timeout 3 (3 for testing, 14 live)


Ext. 400 resides on Site B:

Ext direct-to-VM number is *400


When setting call-fwd all *400 I am unable to repeat the issue

When setting cfwd-noan *400 I will hear ring busy sometimes.


voice service voip

allow-connections h323 to h323

allow-connections h323 to sip

allow-connections sip to h323

no supplementary-service h450.3

supplementary-service h450.12

ephone-dn 55 dual-line

call-forward noan *400 timeout 3

huntstop channel

no huntstop

I have attached output showing the output of deb ccsip messages. Note the disconnect cause code on the bad call. The good call was placed one minute later.



So, I guess the best question is...how to troubleshoot disconnect cause 41?


Thanks!

The debugs is actually just the CDR output, so it doesn't help much.


I'm guessing you're running CME between the routers?


Have you tried adding this to both:


voice service voip

no supp sip refer

no supp sip moved

allow-connections sip-to-sip

There is no debug ccsip message in the attachment.

oops, debugs included this time.


Can you describe the logic of the following:


no supp sip refer

no supp sip moved


Also, should SIP to SIP be on both CMEs?

Before I read further, for voicemail CME C uses IP address of CUE B, not CME B, correct ?

This may be dsp related since g.729 is being transcoded for VM. Trying to figure out how to prove this, though....
