Hi, I am experiencing intermitant low volume incoming calls on CME 4.1 with a PRI. Especially and mostly when doing a group pickup of another extension. There is no discernable pattern to the quiet calls, from various local, national and international numbers.
Any help appreciated.
Hi, I suggest you upgrade to 12.4(11)XJ4 that is the most stable release with most bugfixes.
For the phones I suggest 8.2(2)SR4 alsto latest stable.
I have this combo on many customers, but admittedly they don'use group pick-up.
