Modifying PAI/From fields in SIP Outbound messages

I have a SIP acount that requires dialed numbers going over the SIP trunk to have either

The"From" field or "PAI" field to be something of this nature. 

Telephone number@providerdomain.com

Is their a way to do this in the Cisco router?

Have been trying to use SIP profiles to achieve this with no success.  Any help appreciated.  Thank you.

Example number available on Trunk 7143030988, 7143030989 etc.

Sample outbound debug CCSIP messages captured.

Modifying PAI/From fields in SIP Outbound messages

You can try with a voice translation rule. Something like this:

voice translation-rule 10

rule 1 /.*/ /7143030988/

!

!

voice translation-profile XLATE_CALLING

translate calling 10

dial-peer voice 1000 voip

translation-profile outgoing XLATE_CALLING

...

Modifying PAI/From fields in SIP Outbound messages

Hello Danielle,

Thanks for the suggestion but Voice translation rule will not work here.  There are over a hundred TN on this SIP Trunk.  I dont see how I"II be able to translate "calling" for everyone of them.  To re-explain, all "calling" must be valid TN on the trunk.  With Voice translation rule, I"II have to convert all "calling" to 1 TN.  That is to say all calls will show as coming from 1 TN.  The calls need to show the actual TN calling.  The other alternative given is to include the PAI in the SIP message to show as TN@ispdomain.com (example PAI 7143030988@ispdomain.com) .

Thank you.

Please review regular expression and pattern features before stating that translation rules or SIP profiles cannot  be used.

Modifying PAI/From fields in SIP Outbound messages

Paolo,

I am not stating it cannot be used .  With regards to this scenario using translation rule I can convert any "calling" to 1 valid TN outgoing just as Danielle suggested.  But this will always show calls coming from one number not the real numbers calling.  I said that in my reply.  Maybe I should have phrased it better.

If you know how to use either tool to accomplish the desired result, please post.

Thank you.

Seems like you CUCME is not sending a calling number at all, so you have to fix that first.
