Hi, Edwin!
In this case I think you are right, because the ;user=phone should be an
URI parameter, not a header parameter. Although the syntax is fine, the
semantics change - not sure if that bothers you though.
Please open a bug report to keep track of this issue and point it to
this discussion :).

Hi Răzvan,
After the change to b2bua we present the To header like this:"To:
sip:[email protected];user=phone
After migration we still have problems with certain sip clients. In some
cases a software update did the trick. I will make a github feature request
to add the <> symbols anyway, even if it is following RFC.
In case of adding the ;user=phone, i'm in doubt if you don't have to enclose
the URI because of the semicolon. See RFC 3261:
" The Contact, From, and To header fields contain a URI. If the URI
contains a comma, question mark or semicolon, the URI MUST be enclosed in
angle brackets (< and >). Any URI parameters are contained within these
brackets. If the URI is not enclosed in angle brackets, any
semicolon-delimited parameters are header-parameters, not URI parameters.
