CME phones cant reach CUE - Other phones can reach it

I have a 2821 router running IOS c2800nm-adventerprisek9-mz.151-4.M8.bin. The router has a CUE module:


NAME: "NM-SE on Slot 1", DESCR: "NM-SE"
PID: NM-CUE            , VID: NA , SN: FOC093220KH

NAME: "20GB IDE Disc Daughter Card on Slot 1 SubSlot 0", DESCR: "20GB IDE Disc Daughter Card"


It is running Unity Express 7.0.6.


I am studying for my CCIE Collaboration, so I have set the phones up as SIP.  The phones register, and can call each other.  I have configured the CUE module, and have the info all set up under the voice pool dn's and voice register global.  I can call my CME from a phone on a different cluster.  The calls do make it to voicemail, and I can leave a message.  However, the actual phones on the CME can not reach the CUE module.  They also dont get their MWI's.


Also, the phones are a 7941 and 7961.  I suspect there is an incompatibility with the SIP integration and this CUE module.  But the commands all take.  So I could be wrong.  Unfortunately all of my experience is with CUCM and Unity Connection.  So I dont have a frame of reference.


Thank you in advance.


To rule out the SIP phone

To rule out the SIP phone compatibility you can configure a CIPC (Cisco IP Communicator) on laptop or desktop and can try to reach cue.

And plz attach show run of cme with debug ccsip message & debug voip ccapi inout  of failed call.

Sorry for my ignorance.  I'm

Sorry for my ignorance.  I'm not seeing a way to configure IP Comm as a sip phone.  Under "voice register pool 3", under type, I do not see an IP Communicator option.  Did you want me to use telephony-service and provision this as a SCCP phone for testing?

Yes plz, configure it as sccp

Yes plz, configure it as sccp using telephony-service.

I havent gotten around to

I havent gotten around to doing this yet, but I do beleive it is an incompatibility.  My router has CME 8.6.  I found the compatibility matrix, and this version of CUE isnt compatible.  Unfortunately I have the highest revision of CUE that this hardware supports.  Looks like I'm gonna have to make the $400 investment and buy an NME-CUE off ebay.

To add to what I was saying.

To add to what I was saying.  I decided to try downgrading my CME to a compatible version.  So I was in the process of downloading an IOS that has CME 7.0.1 built in.  I went to download the CME support files, and I see that there is no SIP loads.  I think I just need to face the fact that SIP is not support on this version of CUE.
