Frequently Asked Questions

Find answers to common questions about refurbished telecom equipment, VoIP phones, and business phone systems in Canada

Trust, shipping and buying from Telecom Depot Direct

Yes on both counts. As a Canadian-owned and operated company, we ship domestically — no cross-border customs delays, no surprise brokerage fees, and no currency conversion uncertainty. Orders are priced in Canadian dollars and most ship within 1–2 business days from our Montreal location.

Legacy Systems (Nortel, Mitel, Avaya)

Yes. Nortel phones remain compatible with active Norstar and Meridian PBX systems — the system itself still works, you just need the handsets.
Not necessarily. End-of-support means updates stop, not that phones stop working. Many businesses extend system life by sourcing replacement phones.
We stock certified refurbished Avaya models that are tested and ready to deploy. Your system will recognize them immediately.

Compatibility & Systems

Compatibility depends on matching the phone protocol to your PBX system. Contact us and we will confirm before you order.
Yes for VoIP systems. No for proprietary systems like Norstar or older Avaya.

Refurbished Equipment

Yes. Refurbished means inspected, tested, cleaned, and reset. It is reliable and cost-effective.
Refurbished is tested and certified. Used is not inspected. New has never been deployed.

Conference Phones

Replacing with a refurbished unit is usually faster and more cost-effective.
It depends on room size. Small rooms need basic units, larger rooms require extended range or additional microphones.
