Hi:
I cannot get a headset to work with an M3903 phone.
I checked the CLS but do not find anything different from
the other phones which work fine with the headset.
Using M3903 phones. Opt 61 Pbx
What kind of headsets are you using? I use a Plantronics on my 3903 without any special CLS programming. Just remember that you will need to use the amplifier box with the headset.
