Unity Express v7.0 and CallManager v5.1.2: not recording calls from outside

Answered Question
Feb 9th, 2010

Hello all!


I've recently configured integration between CCM v5.1.2 and Unity Express v7.0 and some features worked properly and I'm able to record calls from Cisco Phones and Cisco IP Communicators. But when outside calls (external and internal, from our Ericsson PBX system) are received, they're not correctly forwarded to the voicemail system provided by Unity Express.


Unity Express module is AIM-CUE= and is installed on a C2851 router, that's integrated with our Ericsson PBX system. External (and internal, not used by CCM v5) calls are forwarded from Ericsson to CCM normally but not forwarded properly when they're trying to reach the Unity Express. When I make a call from cell phone, it rings until I receive a "BUSY" signal from the PBX system, indicating some sort of error, maybe from misconfiguration of Unity Express or CCM or both.


Please, can you help me?


Regards

Hi,

It seem to be a codec problem

CUE accept only G711

So you'll need a transcoder for the external calls to work and add "codec G711" under your CUE dial-peer ,also add allow connections under voice service voip

Wish this be helpful

Thanks

Thanks for your help!

There was also a misconfiguration in Calling Search Space. I've made the corrections and worked perfectly!

Hi!

I have a similar problem as described above. I'm running CUCM 7.1.3 with CUE 7.1.4 on a 2811 (NME-CUE) gateway. A Siemens Hicom PBX passes calls from the PSTN to the 2811 via qsig.

CTI Ports and JTAPI Access seems to work fine. I can access CUE and leave VoiceMail when calling from the inside. If calls come from the PSTN and forwarded to VoiceMail, however, a busy signal is heard. Normal CFA to external destinations works. The correct CSS was used everywhere (CTI Route Point and CTI Ports CSS can access every Partition). The Codec specified in the DevicePool Region of the CTI Ports is G.711, so no transcoding should be necessary (since CUE only supports G.711).

Am I missing something? Do I need additional configuration on the 2811 if I am using CUCM? Would be very happy if someone could give me some advice!!

Here is my Gateway configuration...some output omitted (the extension 171 on CUCM is forwarded to VoiceMail):

I managed to find the solution. After analyzing traces on CUE I discovered an "CTIERR_REDIRECT_CALL_UNKNOWN_DESTINATION" error. I found this thread (https://supportforums.cisco.com/message/320157#320157), which describes a similar problem with IPCC. After adding the CTI ports partition directly to the gateway CSS, CUE answered external calls, skipping any translation patterns.

I am curious as to why this is necessary. Normal CFA works fine for external callers via Translation Patterns. I would be happy if someone could explain it to me..
