[Asterisk-Dev] REFER / NOTIFY methods according to RFC-3515

[lea123 at wp.pl]

I am using Asterisk v1.2.1

In the previous SIP Debug output I put a different "User-Agent:" 
ID to simulate X-Pro Softphone behavior, but it should've been: 
Asterisk v1.2.1

Now, the big question is:
"what should be the Request-URI after the REFER keyword 
according to RFC-3261 ?"

I think the Request-URI should be taken from the top-most Via: 
header in the preceeding INVITE request that begins this SIP 
dialog, but I am not sure...

Could some RFC3261 expert, shed some light on this issue ?


Regards,
Daniel Leeds
