We work with our customers to reimagine the world of business communications and collaboration. This relentless passion to innovate has made us the #1 cloud communications provider worldwide, and we donโt plan on stopping there.
Technology breaks down barriers and unlocks potential, making it easy for people to do their best work together. In todayโs mobile world, this means giving teams, partners, and customers the ability to communicate, collaborate, and connect the way they want on any device, anywhere, anytime. It's what we call collaborative communications, and itโs at the heart of everything we do.
With our flexible, cost-effective cloud communications and collaboration solutions, weโve created the ideal workplace, where business can be done more efficiently and effectively. From an all-in-one cloud phone system with team messaging and video conferencing to a complete contact center and more, we build solutions for every business, no matter how big or small.
Emisar is the last MCP server youโll need to install: a Zero-Trust gateway connecting Claude, Cursor, ChatGPT, and any AI agent to your infrastructure. One server handles production access, debugging, alerts, and internal operations, with new capabilities added as packs. Agents can inspect real production state, debug what they shipped, and help resolve incidents. Safe reads run automatically; policy allows, blocks, or routes risky actions for approval. No SSH keys, VPNs, remote shells, or standing shell access โ and every call is recorded.

Emisar.dev's answer:
emisar is for SRE, DevOps, platform engineering, infrastructure, and security teams that want AI agents to inspect and operate production systems. It is especially relevant to teams managing multiple Linux hosts, clusters, databases, cloud services, or regulated environments where unrestricted shell access and incomplete audit records are unacceptable.
Emisar.dev's answer:
The hosted control plane and operator interface use Elixir, Phoenix, LiveView, PostgreSQL, and Tailwind CSS. The host runner and MCP bridge are written in Go. Action packs use YAML and JSON Schema, while production infrastructure is managed with Terraform on Google Cloud. The system communicates through MCP, OAuth 2.1, TLS, and WebSockets.

Emisar.dev's answer:
Founder Andrii Dryga spent a decade working as a CTO, full-stack engineer, SRE, and DevOps engineer. He experienced the cost of running the wrong command on the wrong cluster, while also seeing AI solve operational problems in seconds. emisar grew from the need to preserve both truths: AI agents are useful, and production access must remain bounded. Its answer is to give agents a reviewed catalog of operations instead of a blank terminal.
Emisar.dev's answer:
emisar lets AI agents work on real infrastructure without giving them a shell. Agents choose from a finite catalog of typed, versioned actions. Policy decides what runs, what requires approval, and what is denied, while an outbound-only runner verifies the action again on the host. New capabilities arrive as packs behind the same MCP integration, and every request is recorded in both a searchable audit trail and a tamper-evident host journal. [
Emisar.dev's answer:
Choose emisar when you want an agent to keep investigating and handling routine operations without handing it SSH credentials or supervising every call. Compared with raw shell access, copy-paste workflows, or one-off MCP servers, emisar provides reviewed action contracts, host-level enforcement, risk-based policy, scoped access, approvals, pack integrity checks, and a durable audit trail. It is built specifically for governed infrastructure access rather than generic automation.

I saw www.calltrackingmetrics.com ; ringcentral.com ; twilio.com ; Zadarma. At this moment it seems that calltrackingmetrics seems to be the first solution I would try because they put in front of their ads the fact to track with google ads. Twilio seems to be too much complex to use and they don't have an iPhone app ; ringcentral I don't know and Zadarma seems good. Source: about 5 years ago
I use unitelvoice.com. It works fine has an app and can forward to my cell number. Used to use ringcentral.com it was fine when it worked but support was crap. Source: over 5 years ago
