Hi,

We are getting hissing noise during keeping the voice mail.It starts after 7-8 seconds while keeping the voice mail.

It is happening between 7975G IP Phones.


Please suggest me to come out from this problem.


Regards,

We had a similar situation, what version of CallManager are you running?

Did you recently upgrade to 5.1.3? Our issue ended up being a bad stick of RAM on our system. Do you see any warning lights on the server?

Please update the phone to latest firmware in CCO first.
