Mapping FXO line to IP Phone/DN not working

[ArSh21]

Hello,

A customer of ours has 8 FXO lines and 50 IP Phones/DNs, They wan to map 6 of the FXO to specific DNs.

Example: Voice port 0/0/1 to be used only via DN 2001, now the Inbound part is ok but the outbound is confusing me.

I followed this link:

https://www.cisco.com/c/en/us/support/docs/voice/call-routing-dial-plans/41887-specific-fxs-call.html

But it didn't work, when dialing 9xxxxxx it gives a busy tone from the 9 digit.

Here's the config:

dial-peer voice 10 voip 
 translation-profile incoming Phone10 
 answer-address 2010
!
voice translation-profile Phone10 
 translate called 3 
!
voice translation-rule 3 
 rule 1 /^9/ /39/ 
!
dial-peer voice 39 pots 
 destination-pattern 39T 
 port 0/0/2

dial-peer voice 39 pots 
 destination-pattern 39T 
 port 0/0/2

Do u need to send 39 to PSTN ? if yes then use the command  "forward-digits all" under dial-peer. Else only the digits dialled after 39 will be sent to PSTN asper this dial-peer configuration.

[ArSh21]

No I don't need to send 93, they're only used to distinguish the calls from 2010.

is this a CME or CUCM setup ?

[ArSh21]

CME

[Roger Kallberg]

As it is CME you can disregard what I wrote as it is from what I know not applicable. With CME your options are somewhat limited and straight up I can’t think of a way to do what you ask for. But then again CME is not one of my usual systems to work in.

[Nithin Eluvathingal]

Use COR.

dial-peer 1 for 0/0/1  in COR 1 and extension 2001 has only access to COR 1

dial-peer 2 for 0/0/2 in COR 2 and extension 2010 has only access to COR 2.

[ArSh21]

Can you help me with a sample config ?

[Roger Kallberg]

Google COR IOS configuration. I’m sure you will find ample examples and you’ll learn while doing it.

In fact the link I posted earlier contains information about how to set up COR.

I configured this remotely and the customer was satisfied!  

Thank you

You’ll need to have a setup to match the inbound call from CM by calling number and then map that call to use a specific FXO port. Have a look at this excellent document for ideas on how to do this. https://www.cisco.com/c/en/us/support/docs/voice/ip-telephony-voice-over-ip-voip/211306-In-Depth-Explanation-of-Cisco-IOS-and-IO.html

In particular Dial-Peer groups would be what you should look at.
