Hi there,
I'm tryng to set up MVA over the following:
CUCM 8.5<--> SIP <--> CUBE <--> SIP <--> ITSP
I've enabled MVA in Service parameters with number 5858 and for a test user, created Remote Destination and RD profile in CUCM and on the CUBE I have
application
service cucmmva http://146.191.205.31:8080/ccmivr/pages/IVRMainpage.vxml
dial-peer voice 5858 voip
description *** INBOUND SIP TRUNK PEER FOR MVA ***
service cucmmva
session protocol sipv2
incoming called-number 5858
voice-class codec 1
dtmf-relay rtp-nte
no vad
dial-peer voice 5555 voip
destination-pattern 5[8-9]..$
session protocol sipv2
session target ipv4:146.191.251.40
voice-class codec 1
dtmf-relay rtp-nte
fax rate disable
ip qos dscp cs3 signaling
no vad
When I call 5858 DDI the SIP call is established but I cannot hear anything.Anything missed?
Attached is debug voice ccapi trace
Thanks

Can you run a SIP debug on the CUBE from the ITSP? I've seen this behaviour before myself and it was because the ITSP was using G.711a and the IVR files on the CUCM are only for G.711u - I had to do transcoding on the CUBE to convert it to u-law.

Yes, that's my conclusion as well. ITSP allows alaw only. I thought the Media termination point in cucm would do the transcoding, though.

Hi Andy,
I've set up the Xcoding on the CUBE:
voice-card 0
dspfarm
dsp services dspfarm
sccp local GigabitEthernet0/1
sccp ccm xxx.xxx.205.32 identifier 3 priority 3 version 7.0
sccp ccm xxx.xxx.251.40 identifier 1 priority 1 version 7.0
sccp ccm xxx.xxx.2.102 identifier 2 priority 2 version 7.0
sccp
!
sccp ccm group 1
bind interface GigabitEthernet0/1
associate ccm 1 priority 1
associate ccm 2 priority 2
associate ccm 3 priority 3
associate profile 1 register XCoder
!
dspfarm profile 1 transcode
codec g711ulaw
codec g711alaw
codec g729ar8
codec g729abr8
maximum sessions 4
associate application SCCP
and then successfully registered the XCoder on CUCM as Cisco IOS enhanced MTP..
I get
hcpgw01#sh dspfarm all
Dspfarm Profile Configuration

Total number of DSPFARM DSP channel(s) 4
but it doesn't transcode, when I call MVA number.
Am I missing something?
Am I right I don't need to use something like this on the CUBE if the XCoder is already registered with CUCM:
telephony-service
sdspfarm units 1
sdspfarm transcode sessions 4
sdspfarm tag 1 XCoder
max-ephones 1
max-dn 1
ip source-address xxx.xxx.201.41 port 2000
max-conferences 8 gain -6

The problem with the way I set up transcoding on the CUBE is the inbound peer has to have alaw (from the ITSP) and the IVR service which requires ulaw is published on the same peer:
dial-peer voice 5858 voip
description *** INBOUND SIP TRUNK PEER FOR MVA ***
service cucmmva
session protocol sipv2
incoming called-number 15858
voice-class codec 1 ---> alaw
dtmf-relay rtp-nte
no vad
There are conflicting codec requirements on the same call leg. Any way to publish the IVR service on CUCM?

OK I managed to configure this - I had to create another call leg to our other gw and forced ulaw.The original gw served as a xcoder.
However, don't know why I bothered and spent the time with this. I really cannot see the benefits of MVA. Enforcing enterprise mobiles to go via enterprise mobile gateway if there's any? Having to put in the PIN all the time is a hassle.
Thanks everybody for their suggestions.

I agree with you, there is no point dedicating a gateway just for a feature like this. Personally I dont see the point of it. SNR is a much richer feature and thats what I see people use often times.

A few examples where MVA could be a good thing:
1) You are a support tech that has to make an afterhours call to a client and you do not want the client to have either your home or cell number because they will use it instead of going through proper support channels.
2) You have a sales staff with realatively high turnover and you do not want to give customers the private numbers for sales people because next week they may be working for your competitor.
3) Have users that frequenly travel the world. Instead of paying global roaming fees they can simply dial into the local office and then make calls.
You can add your PIN to the speed dial to make it easier to make calls for users that use the feature often.

The benefits is MVA or what some people call DISA. Basically having a 1800 number for your company that your employeers could use to place international calls from their mobiles, on the company bill and be able to run CDR reports from those calls placed is usefull.
We have more elaborated features like Dial By the Office, with CUMA integration.
I guess with softphones running on laptops and VPN, having this type of feature for Mobile Phones are less used, it's one of the reasons CUMA will be deprecated at some point in the future.
