this is exactly what im trying to achieve, i want to be able to
check if called party is busy on another call then generate a
different ringback than the normal one i use if not busy. Can u
kindly provide a dialplan example coz im getting confused on how
to track if the ext is busy as well as increment and decrement
the limit value?<br>

its a multi line phone so i guess B is accepting the
call like a normal call which it should with call
waiting enabled on it, if it sent busy then A would
simply hear busy tone which i dont want, i want to
make A hear a different ringtone while call is waiting
so A can know using the tone that B is on another call
and might or might not answer<br>

<div>guess It is the B's function, B is able
to put the call in waiting instead of
respond 486 to FS, when B is already a
call with another party.<br>
</div>
in this case, I'm afraid FS will have no
idea about what is happening in B. <br>
</div>
what branch B is? did you try B's role with
another phone?<br>

i have been using FS in product on many
raspberry pi's and other machines in PBX
environment and everything works well
except im stuck with a requirement which i
cant seem to be able to get over.<br>
<br>
party A calls party B but party B is
already in call with party C, so party A
gets normal ringtone and party B gets call
waiting beeps, how do we detect in FS that
party B is already busy on another call
and generate a different ringtone for
party A which he hears so indirectly party
A knows that party B is already on another
call?<span class="m_3242238943564535639m_-1073053527446265272HOEnZb"><font color="#888888"><br>
