[cisco-voip] Translation Profile out on voice port

[Ahmed Elnagar]

Yes the idea is that I am verifying the concept not a production setup.

The order in which digit manipulation is processed on an outbound POTS dial peer is:

1.	Outbound Dial-Peer

1.	Translation Profile
2.	CLID
3.	Digit Strip
4.	Prefix Digits
5.	Forward Digits

2.	Outbound Voice Port

1.	Translation Profile

You're configuration looks correct to me, so I cannot explain why it's not working for you.  Other than maybe a defect.  In truth, I would have just used the no digit-strip command on the dial-peer.  Think about the resource usage in your method.  You're having the router strip the one off, and then put it back on.  In the no digit-strip method, you simply tell the router to do nothing.  So, 2 tasks versus 0 tasks; which one is smarter?

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
