Yealink T46S EHS36 hangoff problem

[Brian123]

I have the same issue. EHS36 not functioning correctly. Current issues are press button on headset to go on hook and nothing happens on the phone. Press the button again on the headset and the headset base goes off hook and the phone goes on hook.

I'm using a Yealink T48S with EHS36 and Jabra Pro 9450 headset.

My configuration is from the EXT port to EHS36 via RJ45 cord, Out of EHS36 via RJ45 to RJ45 port (AUX) on Jabra base. The other end of Y-connector goes to the handset port on the base station. Out of base station via RJ11 to headset port on Yealink phone.

Currently using 3cx v. 15.5 SP3 with default provisioning templates. I'll do whatever is needed to fix the issue.
