Hey,
I need to rewrite the $tU variable on a packet before it is relayed. It is ok if the change is only on the relayed packet and the $tU variable change. The important thing is that I modify the To header, it seems that rewritting $tU would be the easiest.
$tU is not writable, but just readable. If you want to change the "To" header you should do some "dirty" replacing operation (see textops module).
This is propably something we need to change and make the To and From headers writable. It's not dirty to change them any more.
David: In the original SIP 1.0 protocol the To/From headers was part of the dialog identification, thus you where not allowed to change them in a proxy. THis was kept in RFC3261 - sip v2 - but has been removed in an additional RFC a short while ago (seen from SIP history).
