MVA Feature Functionality

[ahmad_tamneh]

Hello All...

I have the following setup, I am not sure if the will be suitable to enable the MVA feature !

I have CUCM cluster, but his CUCM cluster has no voice GW or DID .. but this CUCM cluster has Inter-cluster trunk to another CUCM cluster which has the DID numbers ?

Can I configure the MVA for this setup..

Appreciate your input.

Hi,

You can add the gateway of the remote cluster to your call manager and configure the MVA

The Gateway in the other cluster is MGCP , and all the PRI are backholded to the ccm

The requirements for the MVA, is h323.

Hi

It is ok to run both MGCP and H323 at the same IOS ,as long as the dial peer isn't a pots dial peer pointing to the PRI it will run independently of your MGCP.

Thank you

But as I mentioned above, all PRI are binded to the CCM!

So how to invok the VXML application while all the DID numbers belong to the MGCP ..

Hi

this the problem , if you have any fxo or any PSTN connection you can finish the task. MGCP not support MVA , this is the problem.

Hi

Firstly many thanks for aokanlawon .That is completely true  , but kindly be informed if you ask Cisco about that it will confirm that only H323 supported . I opened a case with Cisco before regarding to this issue.

Hi

The most example which you can use in your case :

Here is what I think the call flow looks like (5000 is MVA number):

PTSN –> MGCP GW –> UCM (simple enough here) then

UCM with RP to MVA number — routes call to 5000-> H.323 GW then

H.323 — dial-peer to 5010 to UCM –> UCM then

Configuration

1. Add an H.232 gateway in UCM
2. Create a route-pattern for the MVA pilot number.  The partition must be reachable by the MGCP Gateway.
3. Create a PT and CSS to isolate the MVA number.  pt-mva and css-mva
4. Add the MVA under system.  Make sure to use the mva parition on the MVA number and the css-mva on the H.323 Gateway CSS.

The H.232 config is here:

! this translation fixes the caller id back the the pstn number.  The hairpinning overwrites the CLID.
