[Serusers] Problem with REGISTER

[Nils Ohlmeier]

Hello,

i guess your client is not symmetric and not NAT aware. Which means it sends 
out the request on any port (or the NAT rewirtes the source port to any other 
port then 5060) but your Via header says you want the answer back at port 
5060. So the answer never reaches your client.

BTW you should really improve your the code of your UA. It uses all the time 
the same From tag, the same Call-ID, the same CSeq number. This is really 
bad, not RFC compliant and you will probably encounter strange problems with 
other UAs if you keep this bugs.
