Hello,
just to clarify -- did you tried and there were some issues, or just
pure validation of the regex in the subst?
If the second, I would rather use subdt_hf(), but not sure it's in 4.3
or added later. Then instead of \2, I would use $tU (To header username).
Likely you can also completely avoid substitution operations, by doing:
remove_hf("To");
insert_hf("To: <sip:$tU@$rd:rp>;tag=$tt\r\n");
Cheers,
Daniel
