[Freeswitch-users] Two or more simultaneous calls not

[Anthony Minessale]

easier than you think,

Just like Traun had suspected, the methods in the C++ wrapper for the read
app was missing the begin and end allow threads calls
that are only important to python to tell it to suspend the thread state
while FS specific code is being executed.

2 line fix in trunk rev 12958
