mobile voice access can't make call out

somjade.p
Level 1
Level 1

Hi all,

I am able to dial in the MVA number via the PSTN, enter the remote destination, pin, press 1 to make a call then put the number.

The call get stuck for 10 seconds and then get dropped.

Here is the call flow:

Remote user -> PSTN -> MGCP VG -> CUCM -> H.323 VG  to trigger the mva service.

Here is part of the output from debug voice ccapi inout

Feb 15 13:55:34.781 Thai: //87737/0058E0A80200/CCAPI/cc_api_display_ie_subfields:

   ccCallSetupRequest:

   cisco-username=90819010399

   ----- ccCallInfo IE subfields -----

   cisco-ani=90819010399     <=== remote destination number

   cisco-anitype=0

   cisco-aniplan=0

   cisco-anipi=0

   cisco-anisi=1

   dest=59999                        <=== This is the mva number

   cisco-desttype=0

   cisco-destplan=1

   cisco-rdie=74

   cisco-rdn=90838222333            <== This is the number I wanted to dial out

   cisco-rdntype=0

   cisco-rdnplan=1

   cisco-rdnpi=0

   cisco-rdnsi=0

   cisco-redirectreason=10   fwd_final_type =0

   final_redirectNumber =

   hunt_group_timeout =0

I don't know if this is correct if the dest = mva number ? does it have to be the number we want to dial out ?

result from show call active voice compact

     89794 ORG     T0     g729r8 pre- VOIP        P59999          0.0.0.0:0 

It's weird that the codec is g729r8 pre-, since all the dial-peer have been fixed with the codec g711ulaw

Here's the dialpeer

Hi

When you dial from PSTN then you will hit a pots dial peer

So it should be like the below

dial-peer voice 6000  pots

description Inbound dialpeer from UCM for triggering MVA VXML

service mva

incoming called-number (here is the mva number:59999 if this is the mva number)

direct-inward-dial

After that the call will hit the voip dial peer pointed to cucm ip

dial-peer voice 5002 voip

destination-pattern 5....

session target ipv4:10.107.252.32  (cucm ip)

dtmf-relay h245-alphanumeric

codec g711ulaw

no vad

Then when the system authenticate you  and you dial an outside number (example 90044123434556 then you have to have a route pattern to match the destination pattern 9.0044! for example)

Then you will hit the outgoing pots dial peer in vg

example:

!

dial-peer voice 30 pots

destination-pattern 9T

progress_ind alert enable 8

port 0/0/0:15

!

Hi,

That's not the my case,

Call from PSTN is backhauled to CUCM by MGCP and I need to create a route pattern to pass the signaling to H.323 to trigger VXML script then back to the call manager to trigger the mva number.

thanks,

Ah i see

I am not sure if this is supported or recommended, but I have gotten MVA call coming in through an MGCP gateway work by doing the following :

- Get the IP address of the MGCP PRI gw

- On CallManager, create a dummy H.323 gw with that obtained IP address

- Use MVA hairpinning to redirect the MVA call :

- If MVA number is 69541236, and only the last 4 digits is passed to CallManager from the MGCP gw, I would create a Route Pattern 1236 (in a partition accessible by the 'Incoming CSS' of the MGCP gw) and point it to the dummy H.323 gw created

- You can then create a voip dial peer for incoming called-number 1236, with the mva service in VG

dial-peer voice 5001 voip

description Inbound dialpeer from UCM for triggering MVA VXML

service mva

incoming called-number 1236

codec g711ulaw

no vad

- I would recommend configuring  Mobile Voice Acces number to be a different than 1236, to prevent a call loop. It also has to be unique. Let's say 5678 is a unique number for you. You can put in partition 'None', so that everyone can access it.

- Create another voip dial peer for destination-pattern 5678, and back to CallManager

- voice service voip

allow connections h323 to h323

http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/7_1_2/ccmfeat/fsmobmgr.html#wp1126351 walks you through the steps of configuring MVA with hairpinning.

have tried everything and still have no luck.

please suggest

Som

What is the issue after you completed the above steps.Pls describe

if you tried the above and is not working  then i recomenned  to change from mgcp to h323 since the MVA in mgcp gw is not supported

Hi all,

sorry for the late reply,

The issues is solved by reconfiguring the dial-peer.

I mistakenly put the wrong ip address to the dial-peer. I was the call manager publisher which is wrong.

It has to be the call processing node ip address.

Only the ip address of the MVA service that needs to be publisher's.

Thanks all,

Hi Somjade

Glad to hear that.But can you explain  what changes have you done?

Hi chrysostomos,

Here is the configuration:

(FYI, I use MVA with MGCP hairpinning method, call flow is PSTN -> MGCP VG -> CUCM -> SIP VG -> CUCM

7733 is DID

7734 is MVA dn)

application

service CCM-MVA http://10.107.252.32:8080/ccmivr/pages/IVRMainpage.vxml   <=== This has to be the publisher
