The USB Telephone Adapter allows you to add or combine a Skype call and a PSTN call to make a conference call.

• If you are on a Skype call and want to place a PSTN call, dial # 1 + telephone number
• If you are on a PSTN call and want to place a Skype call, dial # 1 + Skype speed-dial *
• To combine two calls (one active, one on hold), dial: # 2

Note: When you combine a Skype call with a PSTN call, only the Telephone LED on your USB Telephone Adapter will be lit.

While on a conference call, dialing # 1 will return you to two separate calls (one active, one on-hold), at which time you can use the call waiting key sequences to switch between or terminate calls.

Note: If you have customised your General settings for the USB Telephone Adapter, the key sequences for call conferencing may be different.
