[Freeswitch-users] analogue flash/recall

Thu Sep 9 19:43:36 PDT 2010

The parameters are in settings, but I put them inside the spans anyway.
No change that I could notice.  Here is what I want to do.

I make a call using the fxo line to an outside number.  Someone calls me
which rings through the same fxo module.  I hear the call waiting beep
on the phone.  I flash the hook and get a dialtone.  What magic do I
have to do to flash the fxo channel so I can answer the call.  In
asterisk they have hard coded *0 to do this, but how do I do the
equivalent in fs to flash the fxo from my analog phone connected to the
fxs module or from anywhere else for that matter.

Your life is like a penny.  You're going to lose it.  The question is:
How do
you spend it?
