That's because we're not a proxy. On Fri, Mar 5, 2021 at 1:26 PM David VILLAUME <david.villaume@sewan.fr> wrote:
I mean that freeswitch sends the Ack on the Bleg, before propagating to the 200 to the A leg.
I would imagine in a bypass media scenario the Ack would handle the 200 with SDP as a proxy, am I wrong about it ?

What do you mean 'locally acks'?

Hello,
In bypass-media mode freeswitch locally acks the 200 ok (SDP), that leads to some Race condition when the party that answered the 200 sends a quick reinvite after Just after the Ack.
I tried on 1.10.1 and 1.10.5, with and without late-negociation, but couldn’t figure how to avoid this.
Has one of you experienced it or have any idea about this ?
