[OpenSER-Users] Strange REGISTER problem

[mark morreny]

Hi,

I am experiencing a very strange problem with REGISTER.  If my SIP client
registers to Openser with openser's internal IP ( 192.168.1.104), then it
works.  But if the SIP client registers using Openser's public IP, it does
not work.  The 200K returned from Openser is different for each case.  For
the 1st case, my SIP client recognizes the 200 OK, but for the 2nd case, my
SIP client will keep on sending another REGISTER upon receiving the 200 OK.


Here are the two different 200 OK msg that Openser sends back to the
client.

Any help will be greatly appreciated.
