[VoIP] WE Earpiece impedance?

[Dennis D Hock]

I am pretty sure it is 135 ohms for a std U1.  Please feel free to refresh my memory.
 
Thanks,

Would anyone know the nominal impedance of the
earpiece from a handset from an old Western Electric
"500" desk set? I can't seem to find the info on any
of my schematics or by Google.

Thanks,

Don
