The Sangoma P310 is a SIP desk phone for entry-level use, designed for deployment in Unified Communications environments. It features two VoIP lines and supports registration to two SIP accounts, making it suitable for small to medium office environments as well as applications in production, education, or retail. The device offers HD telephony with support for wideband codecs such as G.722, as well as narrowband codecs like G.711 and G.726-32, ensuring clear and intelligible voice transmission. Communication is conducted via SIP v2, with security ensured through TLS, SRTP, and VLAN support.

Applications
This telephone is particularly suited for environments where reliable basic telephony functionality is required, such as production halls, schools, retail stores, or home offices. The plug-and-play installation enables quick setup, especially in systems like Switchvox, PBXact, FreePBX, or Asterisk. Support for Hot Desking (from Switchvox 7.8) enhances flexibility for use in mobile work environments.

Functions and Features in Detail
The device includes a 2.4-inch colour display with a resolution of 320 x 240 pixels, which is backlit and thus remains easily readable even in low ambient light. Operation is performed via a 6-way navigation switch, four function keys, and four context-sensitive soft keys. Additionally, keys for headset, handset, speaker, and mute are integrated. A dual-colour LED indicator displays call status, for example, when messages are waiting. The integrated EHS function (Electronic Hookswitch) enables the use of wireless headsets via a 5-pin connector.

Technology Explained Simply
Network connectivity is provided via two Ethernet ports, each supporting 10/100 Mbps. Alternatively, an optional 12-volt power supply connection can be used. Network communication supports VLAN, LLDP, NAT traversal, QoS, and 802.1X authentication, enabling integration into secure corporate networks. Time and configuration management are handled via NTP synchronization and various provisioning methods such as DHCP Option 66, XML management, or firmware updates via a web browser.

Compatibility and Accessories
The telephone is designed for use with Sangoma systems such as Switchvox, PBXact, FreePBX, and Asterisk. It also supports SIP peer-to-peer connections and registration via SIP-URI. The integrated BLF function (Busy Lamp Field) allows display of the status of other lines, enhancing team communication efficiency. Support for 3-way conferencing, as well as the ability to park calls, forward calls, or take over calls, extends functionality for office applications.

Mounting and Installation
Installation is performed via network connection, with configuration possible through various methods such as Sangoma Endpoint Manager, DPMA (Deskphone Module for Asterisk), or XML management. Devices can be configured via DHCP or static IP addresses. Physical mounting is achieved using two Kensington security slots, allowing attachment to a desk or stand. Delivery is in cartons containing 10 units each, with a pallet shipment comprising 16 cartons.

Operational Advantages
The Sangoma P310 offers a balanced combination of functionality and price-performance ratio. HD telephony and support for EHS headsets enhance user-friendliness, while secure network integration and easy provisioning improve operational reliability and maintainability. Integrated features such as call forwarding, call answering, call parking, and conferencing support daily office workflows. Maximum power consumption is 2.5 W, enabling energy-efficient operation.
