[Freeswitch-users] Socket inbound or outbound with PHP?

[Anthony Minessale]

What does 123 lead to? launching another script?

you could make the 2nd originate lead to &park() in place of 123

and you could control both legs from the same socket.

please please join irc and let the whole group help you.
