Hey everyone! I'm reaching out to fellow sysadmins for advice on what services you use for 24/7 IT staff notifications. Currently, our on-prem phone system takes messages and calls the on-call person every 15 minutes if they don't pick up. We're transitioning to Teams for our phone system, but it doesn't have this feature built-in. I know we could create a Power App for this, but I'm looking for a more streamlined, hosted solution. Any recommendations? Thanks!

We’ve found a straightforward method where we just use a separate work mobile phone for our on-call staff. Everyone uses the same number, and whoever is on-call makes sure to activate the ringer before their shift. The night team just calls this number when they need help. In a previous job, we had a pager app that triggered alerts for high-severity tickets, but honestly, just having a dedicated phone works best for us. It might not be automated, but it definitely beats being paged for things like someone misplacing their headset.
Our setup is pretty simple; we use a Direct Inward Dialing (DID) number forwarded to our on-call staff. It keeps things organized and ensures that the right person gets the calls.
We use AnswerFirst to manage incoming calls, then I set up a rotating schedule for who gets called next. The interface isn't the best, but it's cost-effective and it works, which is what counts!
We're using PagerDuty to manage our on-call staff effectively. It can trigger notifications via emails or API calls, and has a built-in escalation path. We’ve integrated it with our alerting and monitoring systems, so it works pretty smoothly!
We have a unique system where we rotate responsibility in person. On our scheduled meeting day, the team member finishing their shift hands an iPhone to the person starting their on-call duty. This keeps it personal and ensures that the transition goes smoothly.
At my place, if a call comes in for the on-call sysadmin, the team calls the switchboard, which pages the appropriate help desk. This way, we had overseas support handling calls at night, prioritizing serious issues before contacting on-call staff.
