Most SIP desk phones treat an intercom call like any other call — audio only, no idea who is standing outside. The D7A is designed around it. Preview, one-button open and monitoring are native intercom features, and the large adjustable-tilt touchscreen makes the door video easy to read from across a reception desk.
See the Door, Open the Door
Native intercom features — camera preview, one-button door release and monitoring — put the visitor on screen before you decide to let them in.
Sixteen Lines, Twenty-Seven Keys
Up to 16 SIP accounts plus 27 one-touch DSS keys and 7 dedicated feature keys cover busy reception, concierge and multi-tenant scenarios without a hunt through menus.
One Cable, or None
PoE 802.3af class 3 over dual-port Gigabit Ethernet means a single UTP run. No convenient cable? Connect over dual-band 802.11a/b/g/n Wi-Fi instead.
Android Under the Hood
The Android OS lets you install apps such as Skype or Zoom directly on the phone, turning one device into telephony, door entry and video conferencing.
Can I see the door camera on this phone?Yes. Camera preview is a native intercom feature. When a 2N IP intercom calls the D7A, the visitor appears on the 7-inch screen and you can release the door with one touch.
How many SIP accounts does it support?Up to 16 SIP accounts, registered to a proxy or used in peer-to-peer SIP link mode for server-free installations.
Does it need a power adapter?No, not usually. It draws power over Ethernet using IEEE 802.3af class 3, so one UTP cable is enough. An optional external AC adapter (5 V / 2 A) is available if PoE is not on hand.
Can it connect over Wi-Fi?Yes. Built-in dual-band 802.11a/b/g/n Wi-Fi (2.4 GHz and 5 GHz) is an alternative to the dual-port Gigabit Ethernet if you cannot run a cable to the desk.
Can it do two-way video calls?Yes, with the optional CAM50 USB camera. It is a 5 megapixel unit with a privacy shutter that plugs into the USB port on top of the phone; the phone handles H.264 and VP8 at 720p.
Can I add more speed dial keys?Yes. The D7A supports up to three colour-screen EXP50 extender modules, adding up to 60 additional one-touch speed dials for busy reception or concierge desks.
Can I mount it on a wall?Yes, using the optional wall mount bracket. Out of the box it ships with a desk stand, and the screen tilts through 48° for comfortable viewing at either height.
Will it work with a headset?Yes. There is a dedicated RJ9 headset port alongside the handset port, a rear USB 2.0 port for USB headsets, and Bluetooth 4.2 for wireless headsets or the optional BTH58 handset.
Is it secure enough for a corporate network?It supports TLS 1.3, SRTP, 802.1p/Q VLAN tagging, IEEE 802.1X, OpenVPN and L2TP VPN, and can be auto-provisioned over HTTPS.
