Hello Daniel,

Thanks for your reply.

The doc of msg_apply_changes is scary.

The use of $fn instead of subst would be something to try to solve this issue? For some cases, I must also change the username part. $fU = anonymous@anonymous.invalid" would be more safety?

Regards,

Igor.

Hello,

if you just want to update the dispay name in From header, you can use:

$fn = "Anonymous";

To avoid conflicts in replacements, use mag_apply_changes() after first changes -- in your case, after subst(...) -- read carefully the docs for msg_apply_changes() to understand its impact and limitations.

Cheers,
Daniel

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
