MSPs judge phone systems the way they judge everything: who actually runs the infrastructure, what the API looks like, and whether the routing engine can express a real on-call rotation. Cannon VoIP holds up under that inspection. We run our own switching, servers and apps, and interconnect with two carrier partners. Our own softswitches and SBCs fail over automatically across regions. The details are public on our network page, and the API and signed webhooks are documented, not aspirational. For voice and texting we rely on only three outside companies, so when something needs fixing there is one accountable company and no finger-pointing between a reseller and a platform vendor. Most feature requests ship in under four weeks, and simple ones often in under a week, depending on complexity.
For the day job: helpdesk queues with callbacks and live dashboards, native Zendesk and Freshdesk integrations that name callers from your helpdesk contacts, and after-hours routing that models a genuine on-call rotation. Flat $34 per extension, no contracts. And if your clients keep asking you about phones, our partner program exists for exactly that conversation.
The helpdesk phone problem, from someone who gets it
An MSP's phone queue is its SLA made audible. When a client's server is down, they call, and a queue that dumps them to voicemail after four minutes is churn in progress. But staffing the phones like a call center is impossible at MSP margins, so the answer has to be routing intelligence: callbacks so nobody sits on hold, escalation paths that reach the on-call engineer, and visibility into what the queue is doing right now.
The other half is documentation. "What did we tell the client on the phone" belongs on the ticket, and any workflow that relies on an engineer summarizing a call after the fact is a workflow that produces empty tickets. Summaries have to write themselves, which is why recorded calls get a transcript and a short summary in the call history, and webhooks can post every finished call to your PSA.
What we set up for MSPs and IT service providers
Why MSPs run, and resell, Cannon VoIP
The economics are clean: $34 per extension, month to month, texting and transcription included, volume discounts automatic at 25 extensions. No contract means the system has to keep earning its seat, which is precisely the standard MSPs are held to by their own clients.
Deployment is the part your techs will appreciate: phones ship preconfigured and register themselves, the VoIP-PNP-MINI appliance ($148) makes client sites zero-config and gives support a secure remote path in, and replacement hardware arrives overnight AM anywhere in the continental US.
And when clients ask "what phone system should we use," you have two answers: point them at us, or make it part of your stack through the partner program, where partners can offer the platform under their own brand, domain, and support number, with our free tools, the eFax test line, and the attestation test line, available to check any client's current setup on the spot.
What a typical setup looks like
A typical MSP runs a support queue, a sales line, and per-engineer extensions at $34 each, with the app on every on-call phone. Tier 1 answers from the queue with callbacks enabled; escalations transfer warm with a whisper first; after-hours emergencies ring the rotation until a human picks up. Every recorded client call gets a transcript and summary in the call history, and a webhook posts it to your PSA.
Client-facing MSPs also use us as the reference install: your own helpdesk running the same queues, integrations, and API hooks you would deploy for a client is a better demo than any slide deck.
Common questions from MSPs and IT service providers
Your clients' industries are covered too: point a law-firm client at our legal page, a clinic at healthcare, a contractor at construction. The whole industries hub is built to be shared.
