NG911 PIDF-LO to ALI

[tmizzell1]

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':

We have many examples of LUA scripts that can be used to modify SIP headers. Hope that helps.

Regards,

David
