[Freeswitch-users] Checking call is connected while bridged in lua

[David Villasmil]

Hello Brian,

In general, you're totally right. But in my case I know the call will never
go through PSTN. Also I've made tests about the header and The FS-B
receives the header fine.

So this works ok for me.

Thanks!

David
