Configuring MVA feature without DID

[Mohammed Al-odhari]

Dear all,
Am having CUCM v8 with H323 GW having Fxo cards, our service provider doesnt support DID feature.After configuring MVA i use my cell phone (771232244) to call the fxo line (05449604- voice-port 0/1/3), i hear fast busy signal after one ring.
H323 Configuration is as follows:
!
voice service voip
ip address trusted list
ipv4 0.0.0.0 0.0.0.0
allow-connections h323 to h323
!
voice class h323 1
h225 timeout tcp establish 3
!
voice-port 0/1/3
trunk-group 11
caller-id enable
!
application
service mva http://10.192.154.8:8080/ccmivr/pages/IVRMainpage.vxml
!
dial-peer voice 2020 pots
service mva
incoming called-number 05449604
no digit-strip
direct-inward-dial
!

destination-pattern 05449604
session target ipv4:10.192.154.8 ; Also there is dial-peer 2021 for subscriber (10.192.157.131)
dtmf-relay h245-alphanumeric

voice-class h323 1
codec g711ulaw
no vad
!
In CUCM:
Enable Enterprise Feature Access - True
Enable Mobile Voice Access - True
Mobile Voice Access Number - 05449604/also i make it empty
Matching Caller ID with Remote Destination - partial Match

-Go to Media Resources > Mobile Voice Access. Set MVA DN to 05449604
- RDP also configured for extension 2122 in addition to RD number (771232244) and i test the Mobile connect feature successfully.

Any help to solve my issue, please.

Thans Jaime for your kind replay, one question please, in the link below it shows the configuration of MVA with pots dialpeer in the H323 Gateway. Pots dialpeer is for PSTN FXO/E1 lines i think, how come it is not supported in the FXO ports as per your shared link.????? Is there any way to make work with FXO line? https://www.cisco.com/c/en/us/support/docs/unified-communications/unified-communications-manager-callmanager/200457-Configure-the-Mobile-Voice-Access-Featur.html thanks again for you.

That's just the protocol to be used, not the kind of port/TDM that is supported.

You have the right protocol, but not the right interface, you need a PRI.
