It`s very simple service to make a notification phone call to himself or teammates.
The service can be used for urgent matters: to alert about accidents,
to request the user to get online/open messenger, etc..
The end-user will receive a call from the PushCall robot phone number.
This number is persistent (PushCall provides 1-5 persistent A-numbers depending on your plan)
and you can save each one to your contacts with the name of the notification type
(f.ex.: Grafana Alert, Slack Notification, Urgent Calendar Event, etc ...).
The call is automatically stopped in 30 seconds or when the user answers.
These calls are free for recipients.
Pushcall provides you simplest way of integration with any alerting system and platform - it is Webhook.
It`s a link (URL) with your number parameter to generate a phone call.
Also, you can use the Slack app to make a phone call just typing a command in chat,
you can use Zapier action to build any integrations
