#851

Assuming this is for the additional delay
May be we can change the speed of the whole text in twilio?

Looking at the template, I see that the fields are not confused as I originally assumed in #851, but there is probably another factor that contributes to the strange message we hear. What could be an example of integration_name? Can it be not raw name as specified in the UI but contain dots or commas?

[greatvovan]

In this example:
https://soundcloud.com/fun-with-no-end/grafana-oncall-sample-notification
The only variant to disassemble the message is seemingly this:
integration_name = Test web hook
title = Congratulations
alert_count = 1

But how to explain the value of integration_name? The value configured in the UI was just "Test". Can it come as "Test, web hook" or "Test. Web hook" by chance? How otherwise explain the pause between "test" and "web hook"?

Approve this change or here is my proposal:

"That's Grafana OnCall. Escalation (title) from integration (integration name) triggered (alert count) times."

[greatvovan]

As per discussion in #851, a part of the problem is that integration_name is not really integration name, but (integration name + type). In my opinion, they should not be concatenated and must be passed into the template as independent fields, to have a freedom of composing the message.

[greatvovan]

For example, I would like it to hear as "Alert via {integration_type} integration {integration_name}, title {title}, triggered {alert_count} times". Currently we do not have such a freedom. Also no accounting for singular/plural form of "time".

Templated example: "Alert via Prometheus integration Production cluster, title CPU usage, triggered 1 time".
