Re: [Serusers] Reg. 500 Internal Server Error

17 Jan 2004

It seems to me that the 500 is not generated by SER and comes from
downstream instead. SER would add Warning and wouls not add Date header 
field to replies. I don't see any obvious reason why the UAS should send
a 500 -- most likely its parser is not too robust and get confused by
some unusual syntax (whitespace in front of 'branch', symbols in branch
value, etc.)

 Hi all,

    I have a private network arrangement as described below.

Cisco Skinny UA (line no:1133)-> Cisco CallManager -> Cisco router(2611XM)->
sipH323 convereter -> SER -> Cisco SIP UA (lineno: 3322).

Their Corresponding IP address are
192.168.6.101 -> 192.168.6.248 -> 192.168.6.250 -> 192.168.6.100(port:5080 for
SIP side, port 1720 for H323 side)->192.168.6.100(port:5060)->192.168.6.103

     I tried calling from skinny phone to sip phone. It doesn't work. 

     I have the default configuration in my SER. I traced message using ngrep on eth0 and
loopback interfaces. I could see that the messages are going from skinny UA to SER and
then the problem occurs. I could see that there is a 500 Internal server error.

     Do I need to configure SER for it to work?. If so, give me an idea of how to do
that.

I have attached the traces below.
