A: Yes, although the headset can only be connected and switched back and forth between two devices at a time. The Plantronics VoyagerPro Headset can be paired with up to four different devices. This is in general for most Bluetooth Headsets with multi-point technology.

A: Technically yes, But…You can use the Plantronics .Audio 1100M USB to listen and talk through SKYPE, but not the dial pad on the handset. You will have to use your pc keyboard to dial a number to make a call. The .Audio 1100M USB was only optimized to use with the MOC (Microsoft Office Communicator 2007).

Here is what Plantronics says:

Ease the transition to Unified Communications with the practical and affordable .Audio 1100M USB Handset. Designed for phone-intensive users not yet ready to manage calls on the PC, the USB handset provides a familiar 10-key dial pad and traditional call control buttons such as answer/end and mute. The Ergonomic .Audio 1100M is optimized for Microsoft Office Communicator 2007. The touch of a button lets users switch to an alternate speaker phone or the PC microphone/speakers when desired. Wide band audio and a noise-canceling microphone optimize audio quality, and a convenient USB cable lets workers plug the device into any computer. Includes a cradle that clips to desktop monitors and laptops for convenient desk management.

A: Yes, but only if you have the AWH-55 plugged into a handset jack. The training adapter will not work if you are using the AWH-55 (or any other system) with one of the Avaya model phones that have a EU24 port and doesn’t need a handset lifter. You would have to unplug the AWH-55 from the headset jack and use it through the handset jack. The Training Adapter will only work plugged into a handset jack on a telephone, it will not work through any of the headset jacks.

A: The new Savi DECT wireless office system with USB interface has a range of up to 350 feet. The Calisto Pro for the home office, which features the same DECT technology and USB interface, has a range of up to 300 feet.

A: Unfortunately, the base unit of the CS351N is not interchangeable with the CS55 headset. The charging unit for your CS351N was designed to hold the CS351 headset, consequently, the contact points match up perfectly with the contact points on that headset. Since the CS55 headset will not fit into your charging unity properly, the contact points will not match up, and the CS55 will not get charged.

A: The Avaya 4610SW IP Phone has a dedicated headset jack. For the H261 Headset to work with your phone, you will need the Plantronics HIC-1 (part # 49323-04) direct connect cable.  An amplifier is not necessary as this set-up uses the volume controls of your phone. This is a cost effective way to use a headset with the Avaya 4610SW IP phone.

A: According to our compatibility guide and research, the Cisco 7912 does not have  a dedicated headset port on the phone, so it does not support a direct-connect headest like the HW261N-CIS, which comes with the connecting cable. It will require an Audio processor (amplifier) like the M22 or AP15. You can use the HW261N (same as the CIS model but without the connecting cable) with either of the two audio processors.

A: First of all, the T10 is just not going to work with a digital phone system (unless of course someone rigged up or installed some sort of analog jack). The T10 is a single line telephone with a headset only for use with an analog jack like you typically have at home. If you try to use a T10 with your digital phone system (digital line), when you press the on/off button to take or make a call, the phone tries to draw an electrical current to operate. Since the typical proprietary digital phone system has no facilities to regulate the current being drawn through it, your analog phone can draw too much current-so much that it fries itself or in rare cases, damages the phone system’s line card. So in a nutshell, the circuitry is just not compatible. This also goes for the T10H and the two line T20 as well.
