That's right. However I don't know why a proxy should remove the From display
name. If you are routing the request to a PSTN gateway and you have UDP size
issues then it's ok, but if not...

I didn't mean that. Instead I meant that your regular expression would work
for the following From headers:
subst("/^From: \".+\" (<sip: *[a-za-z0-9_\....@.*>)/From: \1/ig");
a) From: sip:[email protected];tag=qweqwe
b) From:<sip:[email protected]>;tag=qweqwe
c) From: <sip:user;[email protected]>;tag=qweqwe
d) From: <tel:+12345678>;tag=qweqwe
a) fails because it doesn't use < >.
b) fails because there is no space between "From:" and SIP URI.
c) fails because there are params in the username part but your regular
expressión doesn't allow ";" in the username part. Neither other valid symbols
as ~ are allowed.
d) fails because your regular expression doesn't allow TEL URI's.
