The core of it

Phone system monitoring for 3CX and Yeastar

Your phone system going down is the outage your customers notice first. CommsAlert watches it continuously and tells you the moment something changes — by email and by SMS.

3CX logo

3CX monitoring

The deepest view we offer, built for MSPs running a fleet of 3CX systems. Connect with an API key, an admin login or Sign in with 3CX — it works with 3CX MFA, and nothing is installed on the PBX.

  • Trunks, SBCs and extensions, up and down, with 30 day history
  • Licence expiry, and whether you are running an outdated 3CX version
  • Every 3CX service, plus CPU, memory and disk against your own thresholds
  • Email, SMS and webhook alerts, including Slack
  • Fleet filters, bulk add from CSV and a public page for each PBX
  • Update and backup management across every 3CX, in bulk
Everything 3CX monitoring covers
Yeastar logo

Yeastar monitoring

For Yeastar P-Series — Cloud, Software and Appliance editions. Connects through Yeastar’s own API with a Client ID and Secret, read-only, and nothing is installed on the PBX.

  • SIP trunks, up and down, with seven days of history
  • Extensions on every device: desk phone, Linkus desktop and mobile, web client
  • Model, firmware, uptime, and capacity against your licence
  • Trunk and extension alert levels you set for each PBX
  • Email, SMS and webhook alerts, plus offline and back-online emails
Everything Yeastar monitoring covers

You set the thresholds. Alert when trunks fall below 25% up, when extensions drop below a level that suits your business hours, when disk or CPU or memory passes 90%, or when a licence is inside 30 days of expiry. Set them once as global defaults, or per system.

Also monitored

Everything else that has to stay up

The same alerting, the same logs, the same status pages — across the rest of your infrastructure.

Servers

Any address and port, checked every 10 to 60 minutes, with response times recorded. Re-checked before alerting, so you hear when a server really stops responding.

Webpages

Scheduled checks on uptime and response time, against the HTTP response code you expect — with a log of every check.

SSL certificates

Expiry tracked and flagged well ahead of time, with up to four reminders at the number of days before expiry you choose.

Domain expiry

Domain registrations watched so a renewal you forgot never takes your website, your email and your phones down at once.

Status pages

Status pages that update themselves

When a SIP trunk drops or a PBX goes offline, your customers start calling. A status page answers them first — and CommsAlert keeps it up to date from your monitoring, so you can get on with fixing the problem.

New Updates itself. Link a component to a 3CX, Yeastar, server or webpage monitor and its status changes the moment the monitor does. Emails your subscribers. Customers subscribe to your page and get an email when you post an incident or schedule maintenance. Incidents, maintenance, history. Timed updates as you work a fault, planned work that starts and closes on its own, and 90 days of uptime. Your domain, your brand. A free name.commsalert.com address or status.yourcompany.com with HTTPS, plus your logo and colours. Explore status pages A CommsAlert status page showing All systems operational, a group of SIP trunk components and a portal, each with 100% uptime and 90 daily uptime bars A status page during an incident, with the affected SIP trunks flagged and planned maintenance listed The Components screen in the CommsAlert portal, with components set to follow monitors The Subscribers screen: sign-up form, add a subscriber, import a list and the subscriber list The Domains screen with a custom domain marked Active and its DNS records found The Design screen: logo, favicon, brand colour, appearance and status colours
Beyond the alert

Staff it, and keep the record

Team members

Invite your team and assign roles to control access. Admins manage monitors and settings; viewers can see status without being able to change anything.

Incident history

Every outage is recorded against the monitor it affected, with updates as you work it — Investigating, Identified, Monitoring, Resolved — and a permanent log.

Alerts by email and SMS

Set global alert addresses and mobile numbers once, then override them per monitor. Alerts reach you at any hour, wherever you are.

Alerts

Every check, logged the moment it happens

Servers, webpages, SSL certificates and 3CX trunks are checked on your chosen interval. Anything that changes state is written to the log and pushed straight to your inbox and your phone.
