How to remove tel: URI from PAI Header

[LordJeffers]

I was wondering if anyone knew of a sigma script that will remove the tel URL from the PAI? I have been trying and even tried replacing it but the tel: just gets repositioned.

I think in the server interworking profile there's an option to switch it.

Here might be a good guess though. Remove PAI. Copy Contact to PAI.

Often you need to sigma script the diversion header to overwrite the PAI. In a scenario of call forwarding, diversion is the original called party and PAI is the original calling party and some carriers don't want to see a PAI of a number that's not on your trunks.

within session "INVITE"
{
/*Look for INVITE messages only.*/
act on request where %DIRECTION="OUTBOUND" and %ENTRY_POINT="POST_ROUTING" and %METHOD="INVITE"
{
/*Look for the PAI Header, and if it exist, remove it.*/
if(exists(%HEADERS["p-asserted-identity"][1]))then
{
remove(%HEADERS["p-asserted-identity"][1]);
{
%var1 = %HEADERS["Contact"][1].URI.USER;
%var2 = %HEADERS["Contact"][1].DISPLAY_NAME;

%HEADERS["P-Asserted-Identity"][1].URI.USER = %var1;
%HEADERS["P-Asserted-Identity"][1].DISPLAY_NAME = %var2;
}


}
}
