Buzzing noise from the IP Phone

Answered Question
Aug 18th, 2009

Hi,

We recently upgraded to CUCM 6.1.3(b) from 4.X. Now, we receive a buzzing kind of sound when the speakers are turned on-on a call. We tried upgrading the firmware of 7941G from SCCP41.8-4-2S to SCCP41.8-4-4S. But, we still have the same issue. Can you pl suggest solution.
