ShoreTel SG-90BRI ShoreGear Voice Switch — 90 IP Phone Capacity with BRI ISDN Trunking

The ShoreTel ShoreGear SG-90BRI (manufacturer part 600-1058-20) is a voice switch for ShoreTel unified communications deployments, supporting up to 90 IP phones, softphones and SIP devices alongside BRI ISDN trunk connectivity. Supplied with a 3-month Reboot IT warranty.

Key Benefits

• 90 IP endpoint capacity — Supports up to 90 ShoreTel IP phones, softphones and SIP devices from a single switch, enough for a mid-sized site or a large floor
• BRI ISDN trunk connectivity — Terminates BRI ISDN services directly, the interface still in service across many established Australian and European sites
• Analogue extension support — Keeps legacy analogue devices — lift phones, fax lines, door intercoms, alarm diallers — attached to the same platform
• Distributed call control — ShoreGear switches carry call handling in hardware rather than depending on a single central server, so a site keeps dial tone if the WAN link drops
• Drop-in replacement unit — Matching manufacturer part 600-1058-20, suitable for swapping a failed switch without touching the rest of the configuration
• Tested before dispatch — Powered up and functionally checked by Reboot IT rather than sold untested, with a 3-month warranty behind it

Where This Switch Earns Its Place

This is maintenance hardware, and that is the honest use case. ShoreTel was acquired by Mitel and the ShoreGear line has passed end of manufacturer support, so nobody is designing a new phone system around it. What that changes is where the value sits: for an organisation still running a ShoreTel estate, a tested spare is the difference between a same-day swap and an unplanned migration.

The two situations it suits are growth and failure. Growth, where a site has outgrown its existing switch capacity and needs more IP endpoints without re-platforming the whole deployment. Failure, where a switch has died and the business needs dial tone restored on identical hardware before deciding what the long-term replacement looks like.

Because BRI ISDN remains in service at plenty of established sites, the 90BRI variant specifically is worth holding as a spare where the carrier service is BRI rather than PRI or SIP. Migrating the trunk type is a separate project with its own carrier lead time, and this switch lets that decision be made on a planned schedule rather than during an outage.

Frequently Asked Questions

What does this switch actually do?

It is a voice switch for a ShoreTel phone system — it registers IP handsets, handles call control, and terminates BRI ISDN trunk services. It is not an Ethernet data switch and will not replace one.

Will it work with my existing ShoreTel system?

It is designed for ShoreTel unified communications deployments and matches manufacturer part 600-1058-20. As with any addition to a live phone system, confirm firmware and version compatibility with whoever maintains your ShoreTel estate before installing.

ShoreTel is end of life — why buy one?

Because the systems are still running. If your site is on ShoreTel today, a tested spare turns a switch failure into a same-day swap rather than an emergency migration. It buys time to plan a replacement platform properly.

Why is the warranty 3 months rather than 12?

End-of-support telephony hardware carries a shorter warranty than our mainstream computing stock. The unit is still tested before it leaves us and is covered for 3 months from purchase.

Is a power supply or rack kit included?

Accessories are not guaranteed unless listed. If you need a specific power supply, rack ears or cabling, contact us before ordering and we will confirm what ships with this unit.

What are the shipping costs?

Shipping costs apply based on size and destination — rates are calculated at checkout.
