i have quite a number of 7910 phones installed, and so happened during our testing, we came across the following issues:
1. When the handset in on-hook, the user presses the Spkerphone button, and simultaneously, the Mute button lights up as well..!
The user calls a an external party, and this party is unable to hear the user.
However, when the headset is off-hook, the user presses the Spkerphone button, and only the Spkerphone's LED lights up. This works fine.
2. When a line comes in, the user presses the Spkerphone button to answer, but to no avail! The Spkerphone refuses to answer the call, with the button's LED not lited up.
Hence, is this a hardware issue ?? I tried upgrading the firmware but to no avail, the problem still persists.
any assistance mucho appreciated. Thanks!
