OM80E IP PBX front panel with LED status matrix and interface board slots

Built for port density

Where the OM20G and OM50G are desktop boxes, the OM80E is a rack unit designed around board capacity. Thirteen sub-models run from 8 FXS/8 FXO up to 48 FXO.

Three boards, sixteen lines per board, mixed as FXS or FXO by variant
Two 100M Ethernet ports sharing one IP address, default 192.168.2.240
16 GB internal storage for recordings, voicemail and voice prompts
Analog line dialling delay defaults to 600, against 1000 on the smaller models

AC or DC power for equipment rooms

The OM80E is offered with a single AC module or a combined AC and −48 V DC module, so it can sit in a rack that already runs on DC.

The manual prints two different rear panels for the AC-only and AC-and-DC versions; confirm the power option with the quotation.

Busy-lamp indication for operators

Extensions can publish their status to a console, which is what drives busy-lamp fields on reception desks.

Idle shows a steady green lamp, ringing a flashing red lamp, in a call a steady red lamp
An extension that is offline also shows a steady red lamp
Status subscription works with matching console phones and on ring groups of up to five members

Compatibility boundaries

This model uses standard SIP and the interfaces listed in the specification table. Confirm the PBX, SIP provider or platform against those interface notes before the order; where the documentation does not state a value, the table records it as not stated rather than estimating. PoE, analog port variants, power options and card compatibility are fixed at order time.

Handover, spares and support

Extension plan, provisioning and interface language can be prepared before dispatch. Remote support continues after handover. Spare-part, warranty and service terms are confirmed in the quotation for the models and quantity ordered, so they are not printed as a single figure here.

Frequently asked questions

Can the OM80E record locally?

No. Local recording is offered on the OM20G and OM50G only; the OM80E records to a remote recording server. If you need on-box recording, choose one of the smaller models.

Is DC power available?

Yes. The OM80E is offered with −48 V DC, including a combined AC and DC version. The manufacturer prints two different rear-panel drawings for these versions, so confirm which one you are ordering.

How many extensions can I have?

Three boards give up to 48 analog ports. The manual does not state a maximum number of IP extensions, so we quote SIP trunk capacity instead — 216 trunks, with up to 120 concurrent calls per trunk.

Does it support broadcast?

Broadcasting to analog extensions is supported. Two-way broadcast is not supported by the series.
