Problem: Modem-on-Hold is not working. (V.92 modem Win-
dows users only)
Solution: You may have disabled Call Waiting in your dial up net-
working settings. For example, in the US, if you included
*70, in your phone number to dial, you have disabled Call
Waiting.
Your ISP may not support V.92. Check with your ISP.
Confirm that you have established a V.92 connection.
Modem-on-Hold will not work with a V.90 connection.
Your phone line may not have Call Waiting enabled. In
order to use Modem-on-Hold, your phone must support
Call Waiting/Caller ID (Type 2 Caller ID). Please check
with your local telephone company.
Your modem firmware might be out of date. Please visit
the modem’s Web site to upgrade your firmware.
