[OpenSIPS-Users] modify TO field in the SIP message header

I'd like to chime in here since I had an issue needing this, by the way,
subst changed the header just FINE.. but subsequent message processing was
broken (flood of failed 200OK/ACK on connect followed by far end
Here's my issue, I have customers that dial to me with a prefix indicating
an accountcode (this was necessary because of technical limitations on their
hardware.). I have opensips removing the accountcode from the RURI and
forwarding onto a provider.

When that provider sees the accountcode in the TO header, I get a 400 Bad
Request back from them and they reject the call. If I clean up the TO header
and remove the accountcode from the URI (ie: make it look like $rU) then it
attempts to complete the call but it fails, as I said above, with the 200
OK/ACK flood.

Sorry, not trying to take over your thread. :) But if anyone has any ideas
on how I should handle this, I'd be much appreciative.
