[OpenSER-Users] Changing From: and To: URIs...

Hi Everyone... I'm looking for some advice. Let's say I have a To: header in an initial INVITE: To: Bob <sip:8005551212@sip.example.com> Due to carrier requirements, it really needs to be: To: Bob <sip:+18005551212@sip.example.com> I'm not asking how to do it. I know I can use some textops functions to make this happen. I also know that doing this might break something. The uac module already nicely handles the From: header in a way that doesn't break things. I thought about extending this to handle To:, but I worried that the Record-Route header might get too long for some UAs if I wind up having to change both headers. The To tag must also be dealt with somehow, which I think might make it harder to do than From. Using a 302 response is not an option for me, and I'm really trying to avoid getting a B2BUA involved with this right now. Moving from openser 1.1.1 to 1.3 is enough for me without changing my architecture ;). I'm wondering what would be the best way given what openser can do right now (1.3) to re-write that header that doesn't break anything. I'm not adverse to writing some code to make it happen if that is what is needed. Any ideas? Thanks, Phil
