[SIPForum-discussion] two questions about SIP.

[XIAO Xiaohong]

Hello Folks
two questions about SIP.
 
1) if a terminating UA gets an Invite with Max-forwards=0, it should
discard this message or
continue to process? 
I think the UA should continue process it. What's your view?
 
2) how to distinguish two types of re-Invite? one type is to update
session, another type is
to being as keep alive for example "session-timer".
