Product Q&A
What phone system does it work with?
This is an ANALOGUE conference phone, not an IP one. It connects to a single analogue line through an RJ11 socket — a copper/PSTN line, an analogue extension (FXS port) on a PBX, or an ATA. It does not register to 3CX, CloudPhone (Bicom), Grandstream UCM or Microsoft Teams, and it cannot be plugged into a network switch. CRITICAL FOR AUSTRALIAN BUYERS: with copper retired under the NBN migration, most sites no longer have an analogue line. If this is going into an all-IP site, quote an ATA or confirm the PBX has a spare FXS port at the same time — otherwise the phone will not work on the day it arrives. Avaya’s B100 series is manufactured by Konftel and is a legacy range.
How is it powered and connected?
One analogue line in, via modular RJ11 to a PSTN line or an analogue PBX extension. Mains powered from an external AC adapter (published as 100-240V AC to 14V DC), supplied with universal socket compatibility — price a spare Avaya B100 PSU if the room is hard to access. No PoE, no Ethernet, no Wi-Fi, no battery. There is also no auxiliary port on this model, so no wireless headset or PA system connection — the B159 and B179 have one; the B149 does not. Optional B100 expansion microphones connect by cable to extend coverage.
Key specs — SIP accounts, keys, display, expansion
Konftel OmniSound 2.0 full-duplex audio with a 360-degree omnidirectional microphone. Published reception area is up to 30 square metres for more than ten people. Volume 90 dB SPL at 0.5 m; frequency response 200-3300 Hz, which is narrowband — an analogue line cannot carry HD audio, so do not describe this phone as HD. Three-setting equaliser (soft, neutral, bright); illuminated 128×64 LCD; phonebook holding 50 contacts; conference guide storing 20 groups of up to six people each for pre-programmed group calls; call recording to SD card (supported up to 2 GB, saved as .wav, with an audible beep every 20 seconds that can be disabled). Note that three-way and multi-party calls are set up using a Flash/R-pulse to the PBX, so the PBX must be programmed to allow them and the pulse duration may need adjusting to suit it.
Who is it for and where does it fit?
Small to medium meeting rooms of up to about ten people, on sites that still have a working analogue line or a PBX with spare FXS ports. It is also a reasonable choice where the customer specifically does not want another device on the data network — a boardroom in a secure environment, for example. On an all-IP site, the B179 or a Yealink CP925 is the correct answer instead.
What’s in the box, warranty and AU compliance
Conference unit, power adapter with universal socket compatibility, a 7.5 metre combined power and line cable, intermediate plugs for analogue connection, and quick reference guides — a single cable run serves both power and line, which simplifies a boardroom table install. No SD memory card is supplied, so recording requires one to be purchased separately. Any mains adapter supplied ships with an AU plug and carries the RCM mark; Avaya specifies the adapter as a 100–240V AC unit. Emergency calling: connected to a genuine copper analogue line, this phone keeps working in a power cut only if the line and phone are line-powered — the B149 needs mains power, so it will not. Connected through an ATA, it has the same 000 limitations as any VoIP device. Keep an alternative means of calling 000 in the room.
How does it compare to the nearest model?
Against the B159 and B179: the B149 is the analogue-only entry point. he B159 adds line flexibility — analogue plus a connected mobile, plus softphone VoIP through a PC over USB rather than SIP registration — and the B179 is the native SIP model that runs over Ethernet with PoE. The B149 is also the only one of the three with no auxiliary port, so no wireless headset or PA connection. If the room has a network point and no analogue line — which is now the normal case in Australia — skip the B149 and quote the B179 or a Yealink CP925.
