[OpenSIPS-Users] Remove to-tag from 1XX provisional responses

[Newlin, Ben]

OpenSIPS has a B2B module that you could run on the existing server. There shouldn’t be any need for a B2B server and a proxy server; the B2B would replace the proxy. Unless you just can’t change the config of that server for some reason?

Hi Ben and Alex

Thanks for the quick response. This is exactly what I was worrying about, get unto some unpredictable state like A rejecting some packages.

Agree that putting a B2B in front/back of opensips would solve but it´s another server =(

Thanks for the advices guys!

Not only that, but provisional responses (except 100 Trying) are
required to have a To tag [1]. So you would likely run into issues with
UAs if you start returning messages without them.

That is an astute point.
