[cisco-voip] 7912 on cm 6.1.4a

[Chris Ward (chrward)]

I believe those old 7912s were also very susceptible to excessive
multicast traffic. Not sure how that would cause a static sound but it's
something to look into.

 

Scott,

 

Have you heard the issue for yourself? If not, it might be helpful to
make sure we have the problem description right as static is usually an
analog/HW problem.

seems like I have had more voice issues, since my upgrade from 6.1.2 to
6.1.4a.  I didn't write down the old firmware on 6.1.2.  I know that
8.0.3 was the default for 6.1.4a but i have installed 8.0.4 just know to
see if that helps.  Any other thoughts?

I didn't see any caveats fixed in 8.0.4 related but I thought I would
try.

actually the ones reporting the issue are the 7912g-A.

 

Other ideas?

First thing I'd do is look at the model number.  If they are not 7912G-A
phones then have them all replaced.  The original 7912s had a software
switch that had issues with excessive network traffic and would cause
issues with voice quality and even make the phone reset.

I have a remote site  that is complaining about static.  they seem to be
7912's that are having the issue.  7940's don't seem to have the same
issue.

look in the bug tool kit and didn't find much

has anyone had any simular issues?

Thanks

Scott
