The Yeastar P520 is the entry model of the Yeastar P-Series appliances, built for 20 users and 10 concurrent calls. Two module bays add analog, BRI or one cellular line, which makes it a fit for clinics, small offices and showrooms.
====
The Yeastar P520 is the smallest appliance in the Yeastar P-Series line, sized for up to 20 users and 10 concurrent calls. It gives a small team the tools of a full business phone system (extensions, an auto attendant, a mobile app) in a compact desktop box that needs no rack. Think dental clinics, real estate offices, showrooms and small branches with 5 to 20 staff.
Yeastar P520 specs at a glance
All figures below come from Yeastar's website and installation guide:
- 20 users (extensions) and 10 simultaneous calls.
- Two internal module bays feeding 4 RJ11 ports on the rear panel.
- Up to 4 FXS or 4 FXO/BRI ports, plus one 3G/4G port.
- One WAN port, one LAN port and a TF card slot for storage.
- Powered by the supplied DC 12V adapter.
Build your trunk mix with modules
The P520 ships without fixed telephony ports. Remove the top cover and add two modules: S2 (2 FXS) for analog handsets or a fax, O2 (2 FXO) for landlines, SO (1 FXS + 1 FXO), B2 for BRI lines, or a GSM, 3G or 4G LTE module.
A typical setup for a Riyadh office: an O2 module for two landlines plus a 4G LTE module holding an STC, Mobily or Zain SIM, so outbound calls can go over the mobile network. Yeastar's guide says the cellular module must sit in Slot_1, with the antenna screwed into the rear socket.
SIP trunks need no module at all. Yeastar states its systems are tested with more than 210 service providers.
Linkus and auto attendant for small teams
Every user can run Linkus on iOS or Android, on Windows or macOS, or in a browser. When a sales rep is out at a client meeting, calls to their desk extension ring on their phone and go out under the company number.
The IVR routes callers to the right person ("press 1 for bookings, 2 for accounts"), and voicemail and call recording are built in. Some features depend on the license plan.
Where the P520 fits in Saudi Arabia
- Dental and medical clinics: a reception line, an extension per doctor, an after-hours greeting.
- Real estate, law and accounting offices.
- Showrooms and shops that want a landline and a mobile SIM on one system.
- Startups working from a small office with a team that will stay under 20.
Compatibility and limits
Yeastar auto-provisions more than 500 IP phone models and integrates with Microsoft Teams.
Two limits to know before you buy: Yeastar states the P520 supports neither hotel PMS integration nor the API.
P520 or P550?
The P550 lifts capacity to 50 users and 25 calls and takes 4 modules instead of 2, reaching 8 FXS or FXO/BRI ports and 4 cellular ports, and it mounts in a 19-inch rack. Pick the P520 if your team is under 20 and 4 analog lines plus one SIM are enough. Pick the P550 if you expect to grow soon or need several SIM trunks.
