[cisco-voip] Modify calling number in SIP invite on CUCM 11

Tue Jul 5 11:19:40 EDT 2016

It depends on which headers this external platform is parsing for caller-ID. If it’s using Remote Party ID then this will help you:

M = {}
function M.outbound_INVITE(msg)
msg:applyNumberMask("Remote-Party-ID", "XXXX")
end
return M

I’ve tested this script before, but cannot say it will fit your needs and resolve this issue. What this will do is apply a four-digit mask to your external party number on the Remote-Party-ID header.

You can replace this will “From” if needed.

It actually parses the actual SIP URI, not the display field which, in your case, already contains a four digit extension.

Applying this requires a reset of your SIP trunk - just something to keep in mind.

Subject: Re: [cisco-voip] Modify calling number in SIP invite on CUCM 11

In earlier versions of CUCM we used to get extension number as SIP address for external calls, but after upgrading the CUCM to v11.0 we are getting external phone number mask.

If anyone can help me with SIP normalisation script where I can replace the external phone number mask with extension number in SIP INVITE, which I can apply on SIP trunk to my call recorder coz I want external phone number mask to be displayed on PSTN calls.

Appreciate all help in this.

Thanks & Regards,

It's got the extension in there too in a few fields.  I think it does the Invite this way so the recorder can match up the call from the CTI messages.

Here is the SIP Invite from extension number "1102" with External Phone Number Mask "8889184192<tel:8889184192>", when I dial the internal extension I do receive the extension number in SIP invite:

What does the Invite actually look like?  I wouldn't expect this setup to show the external number mask to the recorder.

Do you have a calling party transform CSS on the SIP trunk?

Hi Florian,

I verified my trunk as well and it is also selected as "OnNet":

Maybe your trunk to the Recorder is set to Offnet, try to set it Onnet

Hi,

The problem I have is that we have active recording system which communicates with the CUCM cluster using a SIP trunk and uses Built-in-bridge configuration.

The invites that CUCM sends via the SIP trunk show the "External Phone Number Mask" rather than the four digit extension when make PSTN calls which will not work according to  the recording system. We need the External Phone Number Mask on phones to display the correct Caller ID.

Can anyone suggest a way to fix this?

Ideally I need a way to modify the number in the SIP invite but I cannot find any example of how to do this.

Any suggestions are welcome.

Thanks
Thanks & Regards,
Deepak Maggo
