3CX is a real PBX and it does that job well. It isn't built for cold-outbound sales campaigns — no lead lists, no dispositions, no predictive dialer for sales, no AMD. If you're comparing the two for a sales team, here's what that actually means.
3CX is priced and built around business phone infrastructure — extensions, ring groups, video conferencing, a PBX for the whole office — licensed by simultaneous call capacity, not by seat. DialerSeat™ is built for one job: running outbound sales campaigns, with lead lists, dispositions, compliance, and a dialer that speeds up or slows down per campaign. Neither product is trying to be the other.
Use DialerSeat™ if you're running outbound sales campaigns — cold lists, dispositions, follow-ups, compliance windows. Use 3CX if you need a general business phone system for the whole office. Plenty of teams legitimately run both: 3CX for company-wide phone infrastructure, DialerSeat for the sales floor's outbound dialing.
3CX licenses by simultaneous call (SC) capacity per system, per year — not per seat — so pricing depends on estimating concurrent call volume, then adding separate SIP trunk, hosting, and support costs on top. DialerSeat™ is $35 a week per seat, billed weekly, with the phone lines, carrier registration, and support already included.
3CX figures are typical published ranges as of 2026 for illustration — 3CX itself notes that pricing shifts with promotions and licensing changes, and quotes a custom price per deployment.
This table is scoped to outbound sales campaign work, which is what DialerSeat™ is built for. On general office PBX features — extensions, video conferencing, ring groups — 3CX is the more complete product, and that's noted honestly below too.

3CX's Channel Partner Program is built for IT/MSPs to sell and host 3CX systems for their clients — but the product itself stays 3CX-branded to whoever's using it. There's no option to run it under your own name. DialerSeat™ Manager+ is a flat $75/month add-on that puts your brand on the platform, no MSP partnership required.
Lead lists, dispositions, and per-campaign tracking. 3CX has queues and ring groups — general office routing, not a sales pipeline.
Every outbound call gets answering-machine detection automatically. 3CX has no equivalent — it's not built to dial cold lists in the first place.
Calling-hour compliance per lead's state, enforced automatically. A general PBX has no concept of this.
$35/seat/week, carrier lines and hosting included. No estimating simultaneous-call capacity, no separate SIP trunk shopping, no hosting decision.
Support is part of the price. 3CX's support model can run about $75 per ticket on top of the license.
Sign up and dial within minutes. 3CX licensing is annual, and getting a system live means sizing capacity, choosing a hosting model, and configuring SIP trunks first.
No capacity planning, no SIP trunk to configure, no separate hosting decision. Self-serve signup means first dial in under 10 minutes.
