[Users] NOTIFY message required fields ??

[Chris Robson]

Is the field "Content-length" a required field in a NOTIFY message?  I 
see that it is part of almost every message from OpenSER except the 
NOTIFY message.  This is causing some issues with Gaim SIMPLe interface 
which processes the header based on the header string "Content-Length".  
Note Gaim does not care about the value associated with the header 
string just the fact that the string "Content-Length" exists.  
Therefore, since OpenSER isnt sending the string, Gaim is core dumping.  
FYI on the core dump.  Yes, Gaim still has a bug on how it is processing 
what it sees as unknown SIP messages which actually is causing the core 
dump, the real problem is the fact that Gaim is processing the header, 
expecting to see the field "Content-length".  So before I report this to 
Gaim as a bug, I wanted to get insight into whether the field is a 
required field.

Thanks......
