Version 3.0/3.1 Poor Speaker phone quality.

[Leemondcomm]

On both software levels with 54** series phones there is an extremly poor speech quality/feedback with transferred calls.
Lines are ISDN. Have tried AGC on and off.

Any other programs im missing here?

Very hard to fix by your description, try and be very specific

Internal to External Transfer > Bad/Good ?
Internal to Internal Transfer. Bad/Good ?

If this is effecting all phones on a module, replace with a known working phone and test.
Possably reflash the module, and if not replace the Module.

Make sure as well you 54XX phone is running the correct build of firmware for the IPO firmware release you are running. Us the upgrade .bat if not correct for 3.1 the verson for 5410 in V2.0.

Umm anotherprivatebuild !!!
