You cannot see alerts unless you are looking. This is one of the biggest problems in monitoring: missing things, going blind.
2:40 AM. An email arrived. Your server is down. You are asleep. Zabbix fired the alarm, sent the email, your phone is on silent. By the time you get to work in the morning, your client knows more about the situation than you do.
This is one of the most common problems faced by IT, monitoring and SOC teams. Zabbix is one of the most powerful open source monitoring tools in the world — but there is a serious gap on the notification side: no voice call support.
Zabbix Default Notification Methods
Zabbix supports the following channels out of the box:
- SMS
- Slack / Teams
They all share one weakness: if you are not actively watching, they do not work.
Notification Channel Reliability at Night
When an alarm fires, how quickly do you find out? The answer depends largely on which channel you are using.
| Channel | Night Reliability | Why |
|---|---|---|
| Low | Lost on silent mode, alert fatigue | |
| SMS | Medium | Carrier delays, single vibration |
| Slack / Teams | Low | Notification sounds usually off |
| Voice Phone Call | High | Keeps ringing until answered |
Alert fatigue is a real problem. When too many notifications come in, teams start ignoring even the important ones. A voice call breaks that cycle — because the phone keeps ringing.
Is Zabbix Voice Alert Possible?
Yes — via webhook.
Zabbix can send an HTTP POST request when an alarm is triggered. A service that receives this request can initiate a phone call. This is exactly where Alertalk comes in. It also reads out what the problem is using AI-powered TTS — so you know what you are dealing with before you even touch the keyboard.
How it works: Zabbix Trigger → Webhook → Alertalk API → Phone Call
When an alarm fires, Alertalk calls the numbers you have defined, reads the alarm text and hangs up. It keeps calling until the issue is resolved.
Which Zabbix Alarms Need Voice Notification?
Not every alarm requires a phone call. But there are certain trigger types where managing them over email is genuinely risky:
- Server or service down alarms
- Disk usage critical threshold
- Database connection failures
- Backup job failures
- Network device unreachable alarms
For these types of alarms, incident response time directly affects business continuity. The on-call team needs to be notified within minutes. Email cannot guarantee that.
Why Email and SMS Are Not Enough
At night, our phones are usually on silent. A single vibration has a very low chance of getting your attention. Alertalk keeps calling until you pick up.
Email and SMS are destined to get lost eventually — because there are too many of them. There is no way to tell if they were read. Critical alerts get buried among the rest. With a voice call, none of that applies. The phone rings, you either answer or it rings again.
Who Is This For?
System administrators, NOC and SOC teams, MSP companies and IT departments managing critical infrastructure. It makes a particular difference for organizations that do not have a dedicated night shift or run a small on-call rotation.
Enterprise teams solve this problem with expensive tools like PagerDuty. Alertalk delivers the same functionality at a significantly lower cost, with native integration for Zabbix and several other monitoring platforms.

Setup takes 5 steps and around 10 minutes. For the step-by-step guide with screenshots:
