Hosted 3CX vs Yeastar P-Series: How to Compare Business Telephony
Last factual review: 2026-08-11 · Written by the team that deploys this stack
Two PBX quotes are comparable only when they include the same call capacity, licence term, hosting, SIP trunks, numbers, handsets, gateways, recording, storage, implementation, training, support, taxes, and renewal responsibilities.
3CX currently prices systems by simultaneous calls rather than simply by user count. A quoted implementation bundle must not be presented as the vendor’s list price or averaged with a differently scoped quote.
3CX where simultaneous-call sizing and hosting fit
- Annual 3CX licensing is based on simultaneous internal and external calls, so concurrency must be measured rather than guessed from staff count.
- The platform supports hosted and self-managed deployment models; the operating owner, backup, updates, security, and recovery path must be explicit.
- 912 has hands-on delivery experience with 3CX, but every public commercial figure requires a current, like-for-like scope.
912 has delivered 3CX telephony for an anonymous professional-services client. That supports implementation experience, not a universal price or a guaranteed call-quality outcome.
The alternatives, treated fairly
A recommendation you can trust has to be honest about what the other options do well. Here is where each alternative genuinely wins — and where its operating model may be a weaker fit for this decision.
Yeastar P-Series
- Cloud, software, and appliance deployment options.
- Unified communications and contact-center capabilities.
- Strong fit where Yeastar hardware or administration is already established.
Choose it when its deployment model, existing hardware, channel support, integrations, and administrator familiarity produce the simpler complete system.
A licence or appliance comparison is incomplete without trunks, numbers, gateways, hosting, storage, implementation, training, support, and renewals.
Buyer decision matrix
These are the factors that should drive the decision — weigh them against your environment, not against any vendor’s brochure.
Measure peak simultaneous internal and external calls, growth, queues, recordings, and contact-center demand.
Normalize every quote across licence, hosting or appliance, SIP trunks, numbers, handsets, gateways, recording, storage, implementation, training, taxes, support, and renewals.
Validate bandwidth, latency, jitter, packet loss, QoS, power, WAN resilience, and remote-user conditions before blaming or choosing a PBX.
Assign patching, backups, certificates, security, fraud monitoring, routing changes, user administration, and incident ownership.
Test CRM, Microsoft 365, mobile apps, call recording, retention, consent, and reporting requirements against the actual edition and deployment.

The verdict
Choose 3CX when its simultaneous-call model, deployment flexibility, integrations, and 912’s delivery experience fit the estate. Choose Yeastar when its appliance, cloud, ecosystem, or operating familiarity is stronger. Compare normalized scopes; two different implementation bundles are not evidence of a vendor price discrepancy.
These recommendations reflect 912’s assessment on the review date shown. Existing licences, device mix, regulatory duties, internal skills, support requirements, and the cost of switching can justify a different choice. Confirm current editions, licensing, compatibility, and commercial terms with the relevant vendor before purchase.
