Volume fluctuations within Unity on ICS7750

[roberts]

Have a customer who is running Unity on ICS 7750 blade that is experiencing an issue where the volume is increasing and decreasing quite dramatically on callers leaving message. All inbound/outbound and internal calls are experiencing no echo or voice quality issues whatsover.

Call manager version is 3.3

Thanks in advance

You might want to try some suggestions on adjusting the audio levels at

You may also want adjust your output attenuation and input gain values on the gateway

I had this same issue one time and used the following document:

http://www.cisco.com/en/US/customer/products/sw/voicesw/ps2237/prod_troubleshooting_guide_chapter09186a0080087146.html

It came down to making the changes to thier default values. If I remember right there was 2 or 3 entry that where set differently, I changed them according to this document and things have been normal since then. Good Luck
