Problem with MWI and SIP UC540

[Chris S]

I have the device setup and functioning correctly utilizing the FXO ports.  I signed up for a SIP provider (NexVortex) and got it working successfully however; the one side effect I've noticed is the MWI stops working as soon as I enable SIP.  Whenever I remove the SIP trunk, the MWI works again. I cannot find how to fix this. Any recomendations?

Check if there a voice bind for SIPto an interface, when enabling the SIP trunk, that you can probably remove.

Where does that typically show up at? I do not see anything in my current config.

Hello Chris,

Which is the IOS version?

Best regards,

Alex

[Chris S]

It is version 15.1(4)M5

Under voice service voip. Ot it could be another wrong setting forced by CCA.

I do not see any binding. The only change I made outside CME in regards to the SIP trunk is to remove the following:

voice source-group CCA_SIP_SOURCE_GROUP_CUE_CME

access-list 5

translation-profile incoming SIP_Incoming

voice source-group CCA_SIP_SOURCE_GROUP_EXTERNAL

access-list 6 voice source-group CCA_SIP_SOURCE_GROUP_CUE_CME

I did this in order to allow the Nexvortex trunk connection successfully. I attached my config if you wouldn't mind looking at it.  I have no idea where the issue is.

Sorry, in my configurations I do not use voice group at all, so can't help.

That's ok - i actually fixed it.  I'm not 100% sure what did it but the only difference between my most recent config and the broken one was that I incorrectly put the domain name in for the SIP trunk. Instead of putting my local domain name, I put the domain of the SIP provider. Works now!
