6. Your problem:

I need to ask a question about routing from within Brekeke:
What field does a re-invite use?
How does it choose the ip to send re-invite towards?

Generally, a re-INVITE will be used for
- Refreshing a SIP Session Timer
- Updating SDP (for example, a UA may want to change a codec during a call...)

The destination IP address of re-INVITE will be indicated in its Route header.
If there is no Route header, the destination will be same as previous destination.

Thanks, I'll follow up with this info. Appreciate your help, as I couldn't find much info in RFC 3261

The SIP Session Timer is defined at RFC4028.
