## Getting help

This page is for businesses running on ComStack. Whether you're setting up your voice agent, configuring channels, managing billing, or troubleshooting something on your site, here's how to reach us.

There are three ways to get help: call our AI support line, email the team, or check the documentation — which is built to be read by AI assistants as well as people.

## Call our AI support line

Our phone lines are answered by ComStack's own AI agent, available 24 hours a day. It can answer questions about the platform, walk you through setup and configuration, and help you troubleshoot — the same way the voice agent works for your own customers. There's no queue and no callback to wait for; you talk to it directly and get answers on the spot.

- **Spain:** [+34 919 935 235](tel:+34919935235)
- **United States:** [+1 415 417 2068](tel:+14154172068)

If your question needs a human or some follow-up, the AI will take the details and route it to the team.

## Email the team

For anything you'd rather put in writing — account questions, billing, bug reports, or a request that needs a paper trail — email [support@comstack.ai](mailto:support@comstack.ai).

To get a useful answer fast, include your project name and a clear description of what you were doing and what happened. Screenshots or the page URL help a lot for anything visual.

We generally reply by the next business day, and usually sooner.

## Read the documentation

Most questions are already answered in the [technical documentation](/docs.md). It covers the MCP server, the REST API, the Chrome extension, and the core concepts behind how the platform works — installation, plans and quotas, languages, permissions, and more.

These pages are deliberately built to be read by AI. If you use ChatGPT, Claude, or another assistant, paste **https://comstack.ai** into the chat and ask your question — the assistant will usually find the answer directly in the docs. It's often the fastest way to get a precise, sourced answer without searching the site yourself.

## Report an issue with the MCP integration

If you connect an AI assistant — Claude, or anything else that speaks MCP — to ComStack, that assistant has a built-in feedback tool on the ComStack MCP server. When a tool behaves unexpectedly, an error message is unclear, or a capability you need is missing, just ask your assistant to report it. The feedback goes straight to the ComStack team, who review every submission. This is the fastest way to flag something about the MCP tools themselves, because the report automatically includes the exact tool and error context.
