Poly Calisto P5300 Wireless Speakerphone

The Poly Calisto P5300 is a portable personal speakerphone that combines Bluetooth 5.0 wireless connectivity with a built-in USB cable. Its 360-degree microphone, full-duplex audio and amplified speaker make it suitable for professional calls, video meetings and multimedia in home offices, remote workspaces and conventional offices.

Wireless Bluetooth Connectivity

Built-in Bluetooth allows the Calisto P5300 to pair directly with compatible smartphones, tablets and Bluetooth-equipped computers. Supported Bluetooth profiles provide call audio, media playback and compatible remote-control functions.

Selected bundles also include a Poly BT600 or BT600C USB Bluetooth adapter. The adapter provides a dedicated wireless connection to a compatible computer, but it is not included with every P5300 package.

Use It Wirelessly or Through USB

The integrated USB cable provides a direct wired connection to a compatible PC or Mac while also charging the internal battery. Users can choose wireless Bluetooth operation for flexibility or connect the USB cable for extended sessions without relying on the remaining battery charge.

360-Degree Microphone Coverage

A digital MEMS omnidirectional microphone provides 360-degree voice pickup around the speakerphone. The rated pickup distance is up to approximately 1 metre, making the P5300 best suited to individual users or participants seated close to the device.

Full-Duplex Audio and Echo Cancellation

Full-duplex operation allows participants on both sides of a compatible call to speak and be heard at the same time. Echo cancellation helps reduce reflected audio, while the amplified speaker provides a broad frequency response for calls, video, podcasts and music.

Up to 16 Hours of Talk Time

The built-in 1,000 mAh rechargeable lithium-ion polymer battery provides up to 16 hours of talk time. A complete charge takes approximately 3.5 hours, and the speakerphone can continue operating through its USB connection during longer working sessions.

Clear Status and Call Controls

Dedicated controls make it easy to manage supported calls directly from the speakerphone. Visual indicators and voice prompts provide information about call, mute, battery and connection status.

• Answer or end supported calls.
• Hold an active call by pressing the call button for two seconds.
• Mute or unmute the microphone.
• Increase or decrease speaker volume.
• Power the speakerphone on or off and enter Bluetooth pairing mode.

Dynamic Mute Alert

Dynamic Mute can alert the user when speech is detected while the microphone is muted. This helps reduce delays caused by speaking without first restoring the microphone.

Microsoft Teams Variants

Specific Calisto 5300-M versions include a dedicated Microsoft Teams button for opening or interacting with the Teams desktop application. Standard UC versions do not include this dedicated button, so the exact product part number should be checked before purchase.
