[reSIProcate] How to handle Re-Invite after Connected

["Kovar, William \(Bill\)" <bkovar@xxxxxxxxx>]

All,

 

I'm trying to understand what I can do in DUM when a RE-INVITE is sent after InviteSession::Connected.

 

I see a transition from InviteSession::Connected to InviteSession::ReceivedReinvite and the OnOffer(...) callback is called. However, I'm not sure what I can/should do in response to that Re-Invite. Additionally, the SDP is not different. Attached are the 2 INVITE msgs:
