ZAC Softphone Notes

  • CS540 + EHS40: Audio works but Answer/Release must be done from ZAC.
    Headset button control does not function with ZAC via EHS40.

ZIP 22G / ZIP 23G / ZIP 23GE Behavior

  • Pressing Answer/Release on headset when phone is idle does not produce dial tone for non-Bluetooth headsets.
  • Must enable in phone settings:
    • EHS
    • Ringing over headset
  • Yealink WH63 on 23GE: Works only when both USB ports are connected (USB + micro-USB to RJ-9 adapter).
  • Ships with setting that keeps audio path always open, which drastically reduces battery life.
  • You MUST disable the “always open audio” setting in Yealink USB Connect software to conserve battery.
  • Battery life (after ~1 year):
    ~4 hours talk time with setting off; much longer standby.
The setting in USB Connect is required to switch between headset idle and active audio modes.
