Hi,
i wonder because when i do a normal call e.g. from directory 220 to directory 240 (all internal), then freeswitch opened 5 channels.
One for that inbound from 220, second, a channel for outbound to 240. Thats ok, but there was 3 addition channels (all with direction=outbound and dest=240 and all the same data (shown in database table core_channels)). Only the uuid is different.
The problem is that, if the callee accept this invite, three hangup-events get fired by freeswitch.
How can i avoid this creation of three additional channels? What are the reason for this channels?
Thanks

It was found that freeswitch performs multiple INVITES.
