[asterisk-users] Robotic sound sometimes

[Rudi Oosthuizen]

>> We experienced this a couple of months ago. It went away when we
upgraded the phones to the latest firmware.
>> Another symptom: temporarily putting the caller on hold cures the
problem sometimes.

We have Snom 320 phones and had similar problems happening in the call
centre intermittently. We resolved by running a weekly script clearing
the 
phones memory. UPGRADES did not work for us. Hope this helps some one.
