Summary:                    Screech Sound (loud noise) heard every 100-200 calls
in call centre environment
Description: 
I have this happening on 3 clients now and it is getting to be a serious
problem.

These machines are connected to existing Phone systems via ISDN to record
calls and to directly connect SIP extensions.

On 2 machines the caller (connected to the existing phone system or via
SIP) hears the screeching sound (or loud noise) and then has to hangup the
call as it does not stop. On 1 machine the callee (on the other end of the
ISDN) hears the  screeching sound (or loud noise) and then has to hangup
the call as it does not stop.

I have the same configuration (i.e. connected to the Teclo and PABX to
record calls) on a number of clients and it works fine with large volumes
of over 20,000 calls per day on the same hardware.

I do not think this is a configuration issue, rather an incompatability
issues with certain PABX systems and we would need to find a workaround for
them.


This is causing me to pull me hair out. If someone can solve this one for
all machines I will make a minimum $500 support payment to the online
community of your choice.
