[cisco-voip] Translation Profile out on voice port

[Daniel Pagan]

Ahmed -

Not sure if I completely follow but are you concerned about the order of operations for digit manipulation in IOS? If you are then I would say your expectation would be correct with digit manipulation in IOS occurring in the following steps and in the following order:

incoming voice-port
incoming dial-peer
num-exp
outgoing dial-peer
egress voice-port

But after reading your email again it looks like you're more referring to the digit stripping that's inherent to POTS DPs... I'd have to test this to confirm but I would imagine the digit stripping would also occur first at the POTS outbound dial-peer level once matched, then voice translation would apply to the [potentially] stripped called party number. Are you saying the dial-peer digit stripping is occurring *after* the voice-port-level voice translation is applied?

Hi all;

It has been a very long time since I posted to the mailing list but you are always the "gateway of last resort" to find an expert reply :)

I was testing voice translation rules on a VGW with the below setup

I want someone to be able to call extensions "1XXX" from a site connected back to back to another site using E1 0/3/0 "H323 GW with CUCM in each site"...I know I could do it with a simple forward-digits all under the pots dial-peer in order for the router to send 1XXX in the ISDN setup insetead of sending XXX.

I am trying to verify the concept of translation profiles but I am having a strange issue, for the below call the pots dial-peer is matched as an outgoing dial-peer but as soon as this happens the debugs shows that the router check if there is a tx profile on the voice port "before making the digit strip" and translate the number and then make a dial-peer match again and then go out of the voice port...is that a normal behavior? My expectation is that the dial-peer should be matched first then apply digit strip and at the exit from the E1 interface translation profile to be applied.

I cannot find any document that explains this part or document this approach...any ideas?

Below is my configuration

Voice translation rule 1
Rule 1 /^0../ /1\0/

Voice translation profile PSTN_OUT
translate called 1

voice-port 0/3/0:15
translation-profile outgoing PSTN_OUT


dial-peer voice 1 pots
destination-pattern 1...
port 0/3/0:15
