Hi Christian,

I finally got around to adding bidirection SIP support to the
SIP helper. Tested with calls crossing a single asterisk box
in multiple directions, everything appears to be working fine.
I also ran the PROTOS c07-sip test-suite against the helper,
it didn't find any problems. If there are no objections from
your side I'll submit it once 2.6.17 is out.

Cheers,
Patrick
