[asterisk-dev] Asterisk REINVITE

[Nitesh Bansal]

Hello,

I'm building an ARI based conference with Asterisk 13.

Scenario:
Peer A dials into Asterisk, mixing bridge is created and channel 1 put into
the bridge.
Asterisk is also told to initiate call to a recording server, so recording
server is
also added into the bridge.
I have noticed that after the initial INVITE completes with the Recording
Server,
Asterisk is doing a REINVITE towards Recording server, this REINVITE has the
same media  IP, media port though SDP version number increases.

I'm really curious why is Asterisk sending this REINVITE on the outbound
leg to
the Recording server.
Any logical rational for doing that?

Many thanks,
Nitesh
