Hello,
I'm doing a subst on the From header for some particular cases, like this one: subst('/^(From|f):(.*)<sip:(.*)@/\1: "Anonymous" <sip:\3@/g'); In the same route (REQUEST_ROUTE called "INVITE"), I do the following: insert_hf("X-CarrierName: $avp(s:carrier_id)\r\n"); For many User-Agent, the X-CarrierName header is inserted after the @ into the user part of the From. So the From: looks like this: From:"Anonymous" <sip:0123456789@X-CarrierName: ABCDE\r\n The domain name part of the From is on the next line: <domain>:5060>;tag=3fdce0-a658bfa-13c4-50029-55941ccd-5eab9369-55941ccd\r\n I can't reproduce. The only potential explanation is that this impact the User-Agent that have the From at the top of the headers. If someone know what could going wrong here. Regards, Igor
