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.
