Mobile Voice Access

Hi All,

I have configured MVA on SiteB (h323 GW) in my practice lab and When I dial the MVA number 30303000 from PSTN to SiteB, the IVR responds with a welcome message "Welcome to Cisco Unified Communication Manager" and ask to enter the Remote destination Number followed by '#' and  than goes silent and the call disconnects in approximately 40 seconds. It never goes beyond this point and does not prompt for the user pin and password. 

Did anyone experienced this problem? or would like to give some inputs on this.  My MVA configuration is as follows:

CUCM Clusterwide Parameters for MVA

1. Enabled Enterprise Feature Access = True

2. Enable Mobile Voice Access = True

3. Mobile Voice Access Number = 3000

4. Matching Called ID with Remote Destination = Partial match

5. Number of digits for Called ID Partial Match = 7

Configure Mobile Access DN

Media Resources TAB ---> Mobile Voice Access

1. Mobile Voice Access DN = 3000

2. Mobile Voice Access Partition = SITE_B-INTERNAL

  • Hi Riz,

    What should be your incoming called-number in the incoming dial-peer? 3000 or 3033000? You are calling from SiteB PSTN line correct? So it should be 3033000.

    Have a try and keep posted. :)


  • It looks like you're missing a VoIP dial-peer to direct the MVA calls to CUCM.

    dial-peer voice 101 voip

    preference 1

    destination-number <Mobile Voice Access DN>

    session target ipv4:<CUCM IP>

    codec g711ulaw

    dtmf-relay h245-alphanumeric

    no vad

  • Hi, i'm dealing with MVA too.

    My scenario is this.

    I have a VG, at the moment with one E1 PRI to cucm in MGCP.

    I can use one more E1 PRI. I'd like to know if it's possibleconvenient to configure the same VG MGCP for one E1 and H323 for the 2nd E1

    to use for MVA. I read about somenthing similar. Can i use the MCGP for incoming calls to MVA number and then H323 for the rest?

    Or can i basically have 2 separate gateway funcionality, one MGCP and one H323 on the same router?


    Thanks a lot!


  • One other thing is make sure that the H323 gateway in CUCM has access to the MVA number as it looks like you are configuring it to lie in a partition.
