On my customer VG, i currently have a situation where my IP Phone will be calling 032804000, and it has been translated to 4000 at VG


!

dial-peer voice 101 voip

destination-pattern 4000

voice-class codec 99

session target ipv4:10.133.140.10

dtmf-relay rtp-nte digit-drop h245-alphanumeric

!

voice translation-rule 300

rule 1 /32804000/ /4000/

rule 2 /032804000/ /4000/

!

However, i'm getting this message on VG debug:

Hi Hunt,


You'll need to include more information.


Where is the translation profile applied?


How is the call being sent to the gateway?


Why is the gateway sending this 4000 number out the PSTN instead of the voip dial peer?


What is the call flow here?

Nick,


IP phone (032804000) towards VG, VG will translate 032804000 back to 4000, then send the call back to a CTI Port in CallManager.


Phone > VG > CTI Port


So i don't want the call to get to PSTN, but i do need the call to get out from CallManager before sending it back in.


THere are 2 translation profile. One is for incoming calls and out is outbound.


!

dial-peer voice 5 pots

translation-profile outgoing MainLine

destination-pattern 032804000

direct-inward-dial

port 0/0/0:23

!

!

voice translation-profile MainLine

translate called 300

!


-----------------


As for inbound back in


voice translation-rule 300

rule 1 /32804000/ /4000/

rule 2 /032804000/ /4000/


!

voice translation-profile pstn

translate calling 200

translate called 100

!


!

dial-peer voice 1 pots

translation-profile incoming pstn

incoming called-number .

direct-inward-dial

Alright, this doesn't really make any sense.


You would first need this command to enable IPIPGW:


voice service voip

allow h323-to-h323


And your incoming pots dial peer is never being hit because this isn't going to the PSTN. It will also not hit your PSTN because it is also sending to PSTN.


You would need an incoming dial peer that would translate the number to 4000.




voice translation-profile voip-loop

translate called 300


dial-peer voice 1 voip

incoming called-number .

codec g711ulaw

no vad

translation-profile incoming voip-loop





hth,
