Signal · The on-call AI agent

After-hours
intelligence.
Built in.

Retire the on-call cellphone. The alerts, escalations, and queue management that turn voicemails and tool triggers into resolutions, automatically.

Signal is the AI agent that watches the platform after the desk closes. Schedule the escalation. Monitor every voicemail box. Tie into your security, backup, and RMM tools so on-call kicks in before the client calls. Notify by phone, text, or email. Auto-login the right tech at shift start. No improvising, no “I forgot to log in,” no passing around the company cellphone every Friday at 5pm.

In short

Signal is the on-call AI agent inside 1Stream. It schedules escalation trees, monitors any number of voicemail boxes, ties into the alerting from your security, backup, and RMM tools so on-call kicks in proactively, sends notifications via phone call, text message, or email, and auto-logs technicians into and out of queues based on schedule. The on-call cellphone gets retired. After-hours coverage becomes a reliable, multi-channel process that runs whether anyone remembers to start it or not. Included in the Intelligence tier.

What Signal does

Four things, done right.

Signal isn’t a separate product bolted on. It’s built into 1Stream, working with the queues, voicemail boxes, and schedules already there.

01 | Scheduled escalations

Plan the tree. Hope optional.

Most MSPs run after-hours coverage by handing around an on-call cellphone. Whoever has it that week answers everything. When they're done, they hand it to the next person. It works, until someone forgets the handoff, until the phone dies, until the wrong person answers.

Signal replaces the cellphone with a real escalation system. Build the tree as far ahead as needed. Set who gets notified first via phone call, text, email, or any combination. Set how long to wait if they don’t respond. Set who’s next, and next after that.

When the trigger fires, Signal walks the tree. No improvising at 2:14 AM. No texting around the team to see who’s up. The schedule does what the schedule says.

02 | Monitor every box. Notify any way.

Listen everywhere. Reach anywhere.

Signal can monitor every voicemail box that matters: after-hours mains, emergency queues, weekend support lines, client-specific boxes. As many as needed, all in one view.

When a message lands, Signal notifies the on-call tech via phone call, text message, email, or any combination. Pick the channel the technician actually responds to fastest. Confirm receipt or fail over to the next person in the tree.

03 | Auto queue login

Take “I forgot to log in” off the table.

The schedule says Mike starts at 8am. At 8:00:00am, Signal logs Mike into his assigned queues. At 5pm when his shift ends, Signal logs him out.

No more SLA misses because someone forgot to log in this morning. No more queue staffing that looks great on the schedule and disastrous in practice. The system matches the plan.

04 | Proactive triggers

Respond before the client calls.

Voicemail is just one trigger. Signal also ties into the alerting from your security, backup, RMM, and monitoring tools. When a SentinelOne detection fires, when a Veeam backup fails, when an RMM trips a CPU threshold, when a disk goes critical, Signal kicks off the on-call response automatically.

Same escalation tree as voicemail. Same multi-channel reach (phone, text, email). Same fallback if the first tech doesn’t respond. The on-call tech is reaching for the keyboard before the client even knows there’s a problem.

Most clients call about a problem after they notice it. Signal’s job is to make sure your team noticed first.

When Signal earns its keep

Built for the moments no one wants to handle manually.

No more on-call cellphone

Retire the company phone that gets passed around every Friday. Signal sends alerts to whoever the schedule says, on whatever channel they answer fastest.

Tools alert before clients do

RMM trips a threshold. A backup fails. A security tool detects a compromise. Signal kicks off the on-call response automatically. The tech is on it before the client picks up the phone.

Multi-client on-call rotation

A 20-tech MSP covering 150 clients runs one rotation. Fair distribution. No client-specific carve-outs to maintain.

SLA-protected queues

Auto queue login means the support queue is staffed at 8:00am, not 8:14am after someone gets their coffee.

Questions answered

Things people ask about Signal.

Six questions about how Signal works, what tier includes it, and how it plays with the rest of 1Stream.

"What is 1Stream Signal?"

Signal is the on-call AI agent inside the 1Stream platform. It handles after-hours coverage automatically: scheduling escalation trees, monitoring voicemail boxes, tying into alerts from RMM, security, backup, and monitoring tools so on-call kicks in proactively, sending notifications via phone call, text message, or email, and auto-logging technicians into and out of queues based on schedule. Signal retires the on-call cellphone and turns improvised after-hours coverage into a reliable, scheduled, multi-channel process.

"Does Signal only react to voicemail, or can it trigger from other alerts?"

Signal triggers on more than voicemail. It ties into the alerting from RMM platforms, endpoint security tools, backup software, and monitoring tools. When an RMM trips a CPU or disk threshold, when a security agent detects a compromise, when a backup fails, when a server goes offline, Signal kicks off the same escalation tree it uses for voicemail. The on-call technician is notified by phone call, text message, or email before the client even calls about the problem.

"How does Signal know who is on-call?"

Signal manages on-call schedules per client and per queue. Supervisors set up rotations and the system enforces them. Holiday and PTO awareness is built in, so the rotation adjusts automatically without anyone rebuilding the schedule. Multi-client MSPs can run a single rotation with fair distribution across their team.

"What happens if the first technician does not pick up an escalation?"

Signal escalation trees support automatic fallback. If the first technician does not respond within the set window, Signal moves to the next person in the tree, then the next, until someone answers or the tree is exhausted. The wait time at each level and the order of notifications are fully configurable.

"Does Signal work with existing queues and voicemail boxes?"

Yes. Signal sits inside the 1Stream platform and works with whatever queue structure and voicemail boxes are already configured. No separate phone system, no separate integration, no setup of a parallel infrastructure. Signal adds the schedule and alerting layer to what is already there.

"Which 1Stream plan tier includes Signal?"

Signal is included with the Intelligence tier of 1Stream, alongside the other AI agents. The Intelligence tier is designed for MSPs that need the full AI-powered automation layer on top of voice and contact center features.

"Can Signal auto-login technicians into queues even if they forget?"

Yes. Auto queue login and logout is a core Signal feature. Based on the schedule, Signal logs technicians into their assigned queues at shift start and logs them out at shift end. This eliminates SLA risk from the "I forgot to login this morning" problem and makes queue staffing match the schedule on paper.
