New issue 185 by crou...@gmail.com: Issues with erratic DTMF and
Clarification of Gather verb
http://code.google.com/p/restcomm/issues/detail?id=185

Known issues

1 - DTMF bleeds when using the gather verb parameter finishOnKey="*" makes
the problem worse. In most IVR, you often hear, enter blahblah and press
star. I had to remove that because it was not stable. Instead I used the
numDigits which will listen for a specific number of digits and send the
action url. This doesn't prevent DTMF from bleeding but it limits the
problem.

2 - the gather verb "action" takes a url like
http://telestax.com/welcome.php, in standard http $_POST, $_GET or
$_REQUEST, the action url can take more than one parameters,

example,
http://telestax.com/welcome.php?username=telscale&password=0000&value=5666.
In RestComm, you are only able to add a single variable to the action
parameter as,
action="http://telestax.com/welcome.php?username=telscale"
if you try to add more variable, you get an exception.


This makes things more challenging. Maybe Thomas and George can clarify
this.

2 - Numbers starting with zeros are often problematic, which means using a
default "0000" pin for the conference test was almost impossible. According
to Twilio, DTMF problems can be related to those using VOIP. I am using a
land line and from my mobile phone, I often get the same problem.

3 - The initial beep you here when you join a conference only works when
you are not the first person in the conference room. You hear the beep if
you are the second participant.

4 - Trying to use local RestComm install for the full conference setup was
slow and erratic. On one occasion it corrupted my RestComm installation
which prevented me from starting starting RestComm, I had to delete and
download another copy.

5 - Getting the number of participants in a conference requires an API
which don't think RestComm has. Twilio has this
