3CX Extension Caps: How They Change Partner Economics and Your Options

3CX has clarified a fair‑use policy that sets a maximum number of extensions per SIM Call license size. 3CX states enforcement will not begin before April 1, 2026, but the published caps redefine planning for low‑concurrency, high‑extension environments like education, hospitality, and healthcare. Many partners will need to uplift license tiers to stay within the new caps. Viirtue gives MSPs a flexible, reseller‑first path to design around real concurrency and automate quote‑to‑cash, usage rating, taxes, and compliance.
