Avaya B189 IP HD Conference Phone

The Avaya B189 is a dedicated VoIP conference station designed for meeting rooms that need clear group audio. It connects directly to an IP network using standard telephony protocols for immediate deployment.

H.323 and SIP protocol limits

The unit operates with H.323 and offers SIP support through a future firmware upgrade. Super-wideband audio and IEEE 1329 Type 2 compliance ensure broad interoperability, but the speaker tops out at 96 dBSp so very large rooms may need extra coverage.

Network and power readiness check

Confirm your LAN provides Power over Ethernet or plan for the separate power supply this model requires. Verify that your call server supports H.323 today and has a roadmap for the promised SIP upgrade before committing.

Questions about this item

How do I choose between the B189 and other Avaya conference phones?

The B189 is the specific model identified by part number 700503700; Avaya does not offer multiple versions or capacities for this product.

What does the 96 dB speaker volume mean in a real meeting room?

The speaker reaches 96 dBSPL, providing loud, clear audio suitable for medium to large conference rooms without distortion.

Which call protocols does the H.323 and SIP support cap in practice?

The phone handles H.323 and SIP signalling natively, with SIP upgradeable in a future release, so it works with most IP-PBX platforms using those standards.
