How to use

Connect the phone to your IP network using the Ethernet ports; the integrated switch lets you connect a PC behind the phone if required. Register the device to your SIP server or PBX with the provided SIP v2 credentials, configure line and codec settings according to your network policy, and assign voicemail and caller ID parameters. Use the handset or the hands-free function to place and receive calls, and operate call services (hold, transfer, forwarding) via the phone’s keys and on-screen indications.

Recommendations

For optimal audio quality, select appropriate codecs according to available bandwidth (for low bandwidth use G.729A/B or iLBC; for higher bandwidth prefer G.722 or Opus). Ensure firmware is up to date and configure QoS on the network to prioritize VoIP traffic. Place the phone on a stable desk surface and avoid exposing it to extreme temperatures or moisture.
