[Serusers] About the Inter SIP Proxy Problem

 Hi,

 There's a possibility that not CSPS but the UA2 is rejecting the 
INVITE ( well, I guess that is the message that you're looking at).

1. It would help troubleshooting if you show the INVITE and associated 
400 message.

2. Additionally, CSPS's error_log in /opt/sip (Solaris) or 
/usr/local/sip (RedHat) might give you an indication of what is going 
on and of course 

3. any debug/log info from UA2. ( What type of hardware/software is it 
anyway ?)

 cheers,
 Jan
