How to config Escalation mail group

[huozipan]

When I receive a Event or alert, A new ticket is created and into a tech-queue and send a "new ticket" notification to group1@system.com.

Buf if engineers in group1 could not resolve this question in 10 minute, the ticket will escalation.

I hope when escalation is triggered, another group expert1@system.com can receive the ticket. How can I config it??

Any idea can help. Thanks.
