Practical relevance that quickly proves its worth in demanding everyday use\nEven the entry-level model COMfortel D-100 is packed with professional features such as self-labelling function keys including LED signalling, context-sensitive soft keys or a headset connection for cordless headsets with Electronic Hook Switch (EHS). Additionally, the intuitive user interface with its illuminated black-on-white graphic display visibly improves day-to-day productivity\n\nJust like its bigger brothers, an all-round visible casing LED ensures that everyone can see you are on the telephone, even if you make calls by using a hidden headset. Incoming calls and missed calls are also displayed conspicuously.\n\nIts functional design looks impressive in any modern office environment. All this makes the COMfortel D-100 perfect for small offices, home offices and call centres.\n\nSystem and Comfort Features\n- 6 SIP identities/accounts\n- 3 simultaneous connections\n- Caller ID – display phone numbers and names from the local and central telephone book from the communication server / cloud PBX1\n- Call waiting\n- Reject calls\n- Do-not-disturb (DND) locally via the telephone or centrally via the communication server / cloud PBX1\n- Pick-up – fetch a call\n- Call parking1\n- Call forwarding / transfer of calls with and without announcement\n- Call forwarding via telephone or centrally via the communication server / cloud PBX1\n- Call on hold\n- Local splitting via telephone or centrally via the communication server / cloud PBX1\n- Local 3-way conference calls via telephone or centrally via the communication server / cloud PBX1\n- Callback on busy or if caller is unreachable1\n- Dial plan for complex dialling rules\n- Telephone book, 2,000 entries locally in the telephone\n- LDAP – access to central telephone books, such as OpenLDAP or Microsoft Exchange\n- Call lists for missed, selected and accepted calls\n- XML browser for displaying central function menus and lists (such as call lists, telephone books)1\n- 5-way navigation keys\n- 4 context-sensitive soft keys\n- Function keys for call forwarding/transfer and volume setting\n- Function keys including LED signalling for access to the call list, voice mailbox1, call on hold, headset operation, hands-free calling/listen-in function and microphone muting\n- 6 self-labelling and freely programmable function keys with 3 levels as well as polychromatic LED signalling\n- Busy Lamp Field (BLF) function for displaying the call and busy status of extensions1\n- Casing LED for signalling active calls and incoming calls\n- Automatic display backlight with adjustable brightness and switch-on time\n- Microphone muting\n- Wall mountable2\n- Telephone tilt angle: 30° or 45°\n- Languages: German, English, French, Greek\n\nSystem Features on Branded Communication Servers\n- Group login/logout\n- Caller ID – display phone numbers and names from a central telephone book\n- Do-not-disturb (DND)\n- Pick-up – fetch a call\n- Call forwarding centrally via the communication server\n- Access to the central telephone book\n- Online name search (reverse search)\n- Busy Lamp Field (BLF) for displaying the call and busy status of extensions\n- Switch central configuration profiles such as day/night switching\n\nAudio Features\n- High voice quality through echo cancellation\n- Codecs: G.722 (wideband), G.711 A-law/µ-Law, G.726, G.729, iLBC\n- Comfort noise generation (CNG)\n- Voice activity detection (VAD)\n- Full duplex hands-free calling\n- 22 ring tones\n- Ringer, receiver, headset and hands-free volume can be set separately\n- Headset connection via RJ45 for cordless headsets with EHS support and wired headsets\n\nSecurity\n- Password-protected web interface\n- HTTPS server/client\n- SIPS (RFC 3261) – encrypted signalling\n- SRTP (RFC 3711/RFC 4568) – encrypted transfer of voice data\n- Transport Layer Security (TLS)\n- VLAN (IEEE 802.1q)\n\nAdministration\nLocalisation including language, time, date and sound\nConfiguration via web browser (HTTPS)\nMass installation via provisioning server:\n- Auerswald redirect server\n- DHCP Options 66/67\n- Configuration update via SIP notify without restarting the telephone\n- Transmission of settings via HTTP/HTTPS/TFTP\n\nSupported Protocols\n- DHCPv4 (RFC 2131)\n- DHCPv4 Option 60\n- DHCPv4 Option 60 (vendor class identifier)\n- DHCPv4 Option 66/67 (host name / filename)\n- DNS SRV-RR (RFC 2782)\n- HTTP/HTTPS (RFC 2616)\n- HTTPS (RFC 2818)\n- IPv4 (RFC 0791)\n- IPv6 (RFC 2460, RFC 8200)\n- IPv6 Dual Stack (RFC 4241)\n- IPv6 Dual Stack Lite (RFC 6333)\n- IPv6 SLAAC (RFC 4862)\n- BLF (RFC 4235)\n- LDAP (RFC 4511)\n- NTP (RFC 958)\n- RTCP (RFC 3550, RFC 3605)\n- RTP (RFC 3550)\n- DTMF: in-band, RTP Payload (RFC 2833, 4733), SIP-INFO\n- SIP/SIPS (RFC 3261, RFC 2543)\n- SRTP (RFC 3711, RFC 4568)\n- TFTP (RFC 1350)\n- TLS (RFC 2246)\n- VLAN (IEEE 802.1q)\n\nSupported Communication Platforms\n- COMpact 4000, 5000, 5000R, 5200, 5200R, 5500R\n- COMmander 6000R, 6000RX\n- COMpact 5010 VoIP, 5020 VoIP (no system functions)\n- COMmander Basic.2, Basic.2 19“ (no system functions)\n- COMmander Business, Business 19” (no system functions)\n- Asterisk\n- IP Centrex solutions, Hosted PBX\n\n- ntuitive user interface\n- 6 self-labelling function keys incl.
