D725 Desk Telephone
For when you need a complete overview of all calls at your finger tips
The D725 has 18 freely programmable multi-colour function keys in three rows – a design that allows D725 users to have a complete overview of all calls at their fingertips. This, combined with the ability to support up to twelve SIP identities, makes the Snom D725 handset an ideal candidate for intensive phone usage.
The D725's Gigabit Ethernet switch meets demanding telephony connectivity requirements, while its USB port enables the use of accessories for greater connectivity options. The optional D7 expansion module can be attached for additional function keys. The advanced speaker and microphone system and the Digital Signal Processor (DSP) ensure that the D725 delivers a cutting-edge audio performance with superior, crystal clear call quality.
