MGCP E1 With Incomming Calls Problem

[mehrdadelectron]

We have new scenario, I added NM-2MFT-T1E1-E1 router module to CUCM as MGCP endpoint & add Route Pattern for outgoing calls .I also add empty translation pattern (with special partition & CSS) for incomming calls to transfer all calls to 1290 extention. 

The Call from inside to outside(PSTN) work corect:

I set my MGCP setting as below:

but when I change PCM Type to a-law, the error changed:

I dont know if PLAR with MGCP is supported on PRI circuits as I never tried it, why not just create a XXXXXXXXXX translation pattern assigned to partition which is only listed in the GW CSS and set the TP to transalte to the desired destination, i.e. 1290?

By the way I really like your icons in your Visio, are these available for download somwhere :-)

Thanks for replay

PLAR configuration in voice-port is not supported with MGCP controlled module, so as I mentioned ,I used translation pattern as you said. But the problem exist.by the way the Visio stencils are default for version 2013.

[Chris Deren · Accepted solution]

Unallocated/unassigned number means the number is NOT being matched on CUCM, make sure the CSS applied to the GW has access to the translation pattern.

[Dennis Mink]

Is your incoming MGCP gateway able to reach the Translation pattern through its CSS?

also can you shed some light on how you attempt to call for that Translation Pattern you mentioned, when a call comes in?

called party transformation?

[mehrdadelectron]

sorry for late reply.

Thanks,you are right,the problem was in CSS for H323 Gateway.
