remove 91 when forwarding to PSTN

[Mario Lopez]

I am having an issue that I can't quite solve.  I am new to Cisco UCM so please bare with me.  Essentially the issue is when a user forwards their line to their cell phone, or any external number, and that number is called from an external line, the caller ID shows up with a 91 prefix.  I found an article on how to remove the 91 when using MGCP but we are using H323.  

Here is the main outbound dial-peer config

dial-peer voice 10 pots
 description Long Distance
 destination-pattern 91[2-9]..[2-9]......
 port 0/0/0:23
 forward-digits 11
!

Any help is appreciated.

Can you provide the following from your gateway:
sh run | s translation

sh run | s dial-peer

Mario,

that configuration output does not contain a dialpeer with a translation rule applied to it

dial-peer voice 10 pots
 description Long Distance
 destination-pattern 91[2-9]..[2-9]......
 port 0/0/0:23
 forward-digits 11

[Mario Lopez]

That is correct.  This is the mess that I inherited.  Unfortunately nothing was documented so trying to put it all together as I audit these routers.

[Dennis Mink]

OK, so let me see if I understand this correctly, someone puts a call forward all on their desk phone to, for instance, point to their mobile. Then some external party will call the desk phone number and the mobile will ring with a 91..........  caller ID.   correct?

what about when that same deskphone calls that same mobile, without any call forward all, what is the caller ID then?

[Mario Lopez]

That is correct.  If a call comes from an external number, the caller ID contains 91.  If the call comes from an internal extension, the caller ID displays the person's DID (10 digit number).  If a person makes a call to the mobile phone directly, the proper caller ID is displayed (10 digit number).

I'll work on getting the screen shots and debug outputs.  Thanks everyone.

Mario,

Since you have the command forward-digits 11, it should automatically be stripping 91. Looks like you have some digit manipulation setup in CUCM.

Can you post screen shot of your H323 gateway below sections:
Call Routing Information - Inbound Calls
Call Routing Information - Outbound Calls

Can you also make a test call and post the following two debugs to start with:

debug isdn q931

debug voip ccapi inout

-Terry

[Mario Lopez]

Here are the files.

Calling Number 2225554444 (external phone number)

Called Number 3336665555 (number deskphone is forwarded to)

[Terry Cheema · Accepted solution]

Quick fix or bandage fix would be to apply below config on your router:

voice translation-rule 10
rule 1 /^91/ //

voice translation-profile CLID
 translate calling 10

dial-peer voice 10 pots
translation-profile outgoing CLID

Normally Telco's would not allow you to display CLID for any range not part of your DID. Though it appears you have digit manipulation happening either in CUCM or using other methods on voice router like num-expansion etc. In the long run you may need to identify the digit manipulation and would suggest consolidate on the gateway using the voice translation rules.

Anyways make a quick test with the above config and let us know how you go.

Easiest way is to use forward-digits as you are, but that only removes the 9, not the 91. forward-digits 10 would send out just the 9..9...... (10 digits)

You could also use translation pattern as such:

voice translation-rule 10

   rule 1 /^91/ //

voice translation-profile StripDigits

    translate called 10

dial-peer voice X voip

    translation-profile StripDigits out

I'll give these a try tonight.  thanks

[Mario Lopez]

I tried these suggestions but 91 was still showing as the callerID.
