## Thursday 3-3 notes ## Thursday 3-3 notes
we probably best keep the perfect negotiation flags, as they are needed for both starting the call AND renegotiation? if only for the former, it would make sense as it is a step in setting up the call, but if the call is ongoing, does it make sense to have a MakingOffer state? it actually looks like they are only needed for renegotiation! for call setup we compare the call_ids. What does that mean for these flags? we probably best keep the perfect negotiation flags, as they are needed for both starting the call AND renegotiation? if only for the former, it would make sense as it is a step in setting up the call, but if the call is ongoing, does it make sense to have a MakingOffer state? it actually looks like they are only needed for renegotiation! for call setup we compare the call_ids.

so if we don't want to bother with having two call objects, we can make the existing call hangup his old call_id? That way we keep the old peerConnection. so if we don't want to bother with having two call objects, we can make the existing call hangup his old call_id? That way we keep the old peerConnection.
