Software MTPs do not register with SCCP-CUCME IOS Router

Hi.

 

I have configured Software MTPs in Cisco IOS 4331 and I cant register them.

 

IOS: 16.9.4

Router: ISR4331/K9

The above configuration is already configured in a CISCO3925-CHASSIS without any problems.

Also other dspfarm profiles are registered successfully.

Hope this isn't a silly question, but when you say "The above configuration is already configured in a CISCO3925-CHASSIS without any problems." can you confirm that you don't mean literally the same configuration, but that each device uses a unique name for its profile.

Just realised this is CME not CUCM.  So in that case of course the device name is only locally significant.  Under telephony-service, does the tag number in "sdspfarm tag" need to match the dspfarm profile number?

I don't think the tag needs to match, just the name.  Here is CME admin guide which includes MTP example for reference:

Have you tried issuing "no sccp", "sccp"?  What does debug sccp show?

Below is the correct configuration. The sdspfarm tag was a typo here.

Attached is the "debug sccp all" output.
