Over the weekend I upgraded a 3300 MX release 9 to an MXeIII MCD 6sp2 platform, reusing a quad DSP and dual T1 card, otherwise everything remains the same, all 5330 and 5340 sets except one Navigator phone, 2 old ASUs... now users are reporting IP set to set calls sound tinny and like talking through a hollow log, but external calls and calls to analog sets are fine.
Any ideas?
