T46G Multiple EXT Port

[amandah]

We have T46G handsets with extension of an EXP40 to give the Receptionists additional numbers.

They use Jabra wireless headsets and asked for a way to remotely answer calls.
We purchased the YEALINK Wireless headset adapter EHS36.
It works great, but the only problem is it uses the same extension port as the EXP40.
Is anyone aware of a product that we can use that enables the use of 2 extension ports on the T46G handset?
Any other suggestions if not.
