Good Morning!
Guess my debug was a bit confusing with so many domains and
ip-adresses, i'll try to explain it better:
The invite is started from a phone registered on a different
openser-proxy (otherproxydomain.org), goes via this
otherproxydomain.org-openser and a mgw (2xx.xxx.xxx.97, MyMediaGW1) to
the test-openser (proxydomain.org, 2xx.xxx.xxx.x06) which changes the
prot to tcp and sends it to the UA (6x.xxx.xxx.x93).
2xx.xxx.xxx.97 and otherproxydomain.org are not relevant actually,
the interesting hosts are 2xx.xxx.xxx.x06 and 6x.xxx.xxx.x93 where the
main transaction(protocol change to tcp, avp-lookups) and the "rebounce"
of the "302" should happen.
I'm not sure if my understanding of how it should work is correct:
The UA answers with a 302 and a CONTACT-field of
"[EMAIL PROTECTED]:5065" - is this the correct behaviour or
should the UAs reply contain
"[EMAIL PROTECTED]:5065" in the CONTACT-field so it can be
relayed without further modification?
If the latter is true, i guess i'll have to modify the INVITE so the UA
can answer correctly?! I'm happy with a raw guideline of how it should
happen and which tools to use, i'm just not sure what is wrong in the
first place.
thx
Christian
