Review of IP-phone Snom D712 (and a little D710)
Today we’ll talk about the new Snom D712 IP phone, which looks exactly the same as the long-released D710. They differ in only one function. But first things first.
As the index suggests, the D712 is a low-cost model for the Snom D7xx line. More precisely, this is the youngest model. The D712 replaces the D710, which is now being discontinued. But since the stocks of the "old" model are still large, you have every chance to meet it on sale.
As I said, externally the D712 is completely identical to the D710, so you can only distinguish them by the nameplate on the bottom.
The appearance of the D712 is strict and modest, but not old-fashioned.
The four-line display with four function buttons on the D712 / 710 is the same as on the D725 . Below them is a traditional four-way navigation “joystick” with two buttons on the sides - “confirmation” and “cancel”.
The programmable buttons on which you can “hang up” a call to specific subscribers or other actions, the D712 / 710 has five pieces. For them there is no additional display, so the functions of the buttons will have to be signed manually on a piece of paper. However, you can increase the set of programmable buttons using the Snom D7 expansion module .
The tube shape of the D712 / 710 is simple, but ergonomic, fits comfortably in the hand.
Under the handset is a large, pretty speakerphone speaker grill.
Not only the display backlight is responsible for the “visualization” of the phone’s activity, but also the large red LED in the upper right corner, as well as the red and green lights in different buttons.
Like all models of the D7xx line, the D712 / 710 is equipped with a large and stable quick-release stand, which can be installed in one of two positions so that the phone is at an angle of 46 ° or 28 °.
In addition to the headset port, the D712 / 710 is equipped with two RJ45 ports and a 100-megabit Ethernet switch.
The phone can be powered by PoE technology, that is, at least one wire at the workplace will be less.
D712 / 710 supports up to 4 SIP accounts, this is enough to implement most business scenarios. The phone is equipped with an address book for 1000 entries and a log of outgoing / incoming / missed calls. Thanks to the integrated XML browser, the D712 / 710 is fully configurable remotely. There is a function of automatic number redialing, if your subscriber has a busy line, you can activate the “do not disturb” mode, automatically answer incoming calls or turn on call waiting from a specific number. The phone can handle up to 4 calls at the same time - calls can be put on hold, at this time music will play your interlocutor. As with older models, you have access to the standard feature of Snom phones - three-way conference calling.
D712 supports the following protocols:
- SIP (RFC3261)
- DHCP, NTP
- HTTP / HTTPS / TFTP
- LDAP (Directory)
- IPv4 / IPv6
And here lies the difference between the D710 and D712 - only the new product supports IPv6, the D710 does not have such an opportunity.
As for audio codecs, both models support the same sets:
- G.711 A-law, μ-law
- G.722 (Broadband)
- G.726, G.729AB, GSM 6.10 (FR)
There is voice activation, a comfortable noise generator, and built-in ringtones that can be assigned to different subscribers. As for information security, the D712 / 710 supports a whole bunch of protocols and technologies:
- 802.1X Authentication and EAPOL
- SRTP (RFC3711), SIPS, RTCP
- Password protected web interface.
- VPN support.
- VLAN (IEEE 802.1Q)
- LLDP-MED, RTCP-XR
Snom D712 is already on sale and will begin to gradually displace the D710 from warehouses. Models are completely interchangeable unless you need IPv6 support. Otherwise, ask D712 in stores in your city :)
