Good morning,
I am attempting to figure out how to use a SBC to rewrite a SIP Invite and extract the Presence Information Data Format PIDF-Location Object (PIDF-LO) and rewrite it in a standard Automatic Location Information (ALI) format.
The PIDF-LO is embedded in the body of the SIP Invite and has a Content ID (CID) that points to it.
If anyone has any idea or could point me to a reference, it would be greatly appreciated.
Thanks

Have you looked at the 'SIP Normalization and Transparency':
https://developer.cisco.com/site/uc-manager-sip/documents/sip_normalization_trans/
We have many examples of LUA scripts that can be used to modify SIP headers. Hope that helps.
Regards,
David
