Getting IP from connection information is totally wrong, because this parameter 
keeps media server IP and it can be different from Invite sender. You can take 
a look RFC 3261 for headers' area of usages.

Subject: [Sip-implementors] retrieve sender IP address
 
Hi all,

I 'd like to retrieve IP address of INVITE sender. Today I retrieve it from
Contact header field. But is it a good idea ? What about retrieving it from
Message Body (from creator/owner (o) or connection information (c) ) ?

thanks for your help
