[Serusers] Strange problems

[Alex]

Hi guys thanks for any help, i got a lot of useful information from this list.

I will try to explain my problem.
i have 2 linux servers :

1- server
Red Hat Linux release 9
ser + freeradius 0.9.3 + radius client

2-server
Red Hat Enterprise Linux AS release 3
ser + freeradius 1.2 + radius client 4.8

I trying to register my ip phone  through ser + radius .
On the 1 server it's working fine i receiving register requests, i can
see that in the logs, and the request is going through the
authentication process.

On the 2 server  i receiving register requests, but it's not going to
the radius authentication, i don't see anything inside the radius
logs.

Here is the ngrep on port 5060: from the 2 server

Daniel and Alex send some explanations i really appreciate that, but i
don't know where to start to fix that problem, i am trying to
understand why on the first server it's working , but on the second
it's not working . both of them have the same configuration only the
versions are different.

I tried to connect different ip phone and it's sending the packets to
the 2 server and it's working, but the 1 ip phone not working with the
2 server, but with the 1 one it's working fine, i just changing the
sip proxy ip.

Thanks for any help.
