In order to achieve true "hold button" activation, we created a small module called a TEHMA (telephone extension hold music activator). This line-powered activator sends a signal down the phone line telling the MOH 500e unit whether or not the phone is on hold. Only phone extensions with a TEHMA can put a call on hold with the phone's hold button.  Extensions without a TEHMA can put a call on-hold py pressing the * key twice.

Phones without a TEHMA can put a call on hold by pressing the star key twice and then pressing the phone's hold button. Click here for instructions on how to connect the TEHMA to an ordinary analog or cordless phone.

The OHP 7500, OHP 6500 and MOH 500e ships with 2 TEHMAs. Order additional Tehma activators to achieve true "hold button" activation

If you've been waiting for the right solution for adding the professional sound of on-hold audio to your phones, your wait is almost over!
