one of our customers has 4 M700 in a multicell system and 4 M25 connected to it. 3 of the 4 M25 have no volume icon on the display and one has it (one icon more than the other). I didn't find how to remove it. The customer is scared that the employees play with the sound and than the handset doesn't ring. Do you know how to remove it?
Best Regards Andy
are you taking about the audio settings icon? This should always be present.
Which firmware version has your handsets with no icon? And the one with it?
yes audio settings (sorry for my english). All base station and handset was installed with actual firmware and all handset should have the same config. I dont know how he could remove the icon on three handset!
