CME with SIP Trunk and Cisco Unity Express

[danm]

I have a Cisco 3745 running 12.4(11)XJ2 / CME 4.1 / CUE with our PSTN access through a SIP Trunk. Everything is working ok except access to Cisco Unity Express, when it gets transferred to VM the caller hears fast busy tone.

Any Ideas? Thanks in advance.

Hi,

Are the calls coming in with G.711? Nothing else would work with CME.

Does it fails only when transferred, or also when calling main VM number directly ? If the first, you may need to configure:

voice service voip

allow-connections sip to sip

no supplementary-service sip moved-temporarily

To confirm collect output of "debug ccsip message" with "term mon" to know a little more.

Hope this helps, please rate post if it does!

Hi Damm,

Did you solve your problem, because I'm having the same problem. Could you help me please ?

Please check the dial-peer configs. Sample configs below.

dial-peer voice 200 voip

description CUE-Voicemail

destination-pattern 8000

b2bua

session protocol sipv2

session target ipv4:1.1.1.1

dtmf-relay sip-notify

codec g711ulaw

no vad

Arun Thomas,

I verified the dial-peer and it doesn't have two commands "dtfm-relay sip-notify" and "no vad". After I put both commands solved my problem.

Thank you very much.

Happy to see that your issue is resolved. but i dont think that its the dtmf command but may be the "no vad"
