[sebastiandm]

Hi Guys,

i have a problem where i am getting white noise when setting up a conference call. This is intermittent and i have noticed it occurs when the G722 codec is advertised but then 5mins later when trying again it works fine but then the G711 is advertised....any ideas ?

Which type of CFB you are using,

what CUCM version?

Always using the same CFB ?

where is the physical locations of CFB?

how many CFB in MRGL ?

Hi,

The CFB is Cisco IOS Enhanced CFB, CUCM version is 6.1.3, the CFB is local to the site and there is only one CFB in the list.

Have you tried disabling advertise G722 codec.

We had a similar problem and it was related to us using both a software and hardware conference bridge.
