AI receptionist that answers calls while you run your business

Help me set up Upfirst (https://upfirst.ai), an AI receptionist that answers calls for businesses. Guide me through the setup end to end.

Read these docs first so you know how Upfirst works:
- Setup guide: https://upfirst.ai/docs/setup-guide.md
- Call forwarding guide: https://upfirst.ai/docs/call-forwarding.md

Then walk me through these steps, one at a time:

1. Account. Start by asking me if I already have an Upfirst account. If not, send me to https://app.upfirst.ai/sign-up to start a free trial. Stay with me through sign-up until I pick my Upfirst phone number. Picking a number doesn't change my current business line.

2. Connect. Help me add Upfirst to this chat. It's in Claude's connector directory and ChatGPT's plugin directory, so I just add it and sign in. Once connected, run get_account_overview and tell me what you see. If my receptionist has no phone number, tell me to finish sign-up first.

3. My business. Use what you already know about me, and read my website if I have one. Then ask only for what's missing, in one short list.

4. Setup. Following the setup guide, set up my greeting, what my receptionist knows, which calls to transfer, and texts to send callers. Tell me what you set up in plain language. For anything that can only be done in the Upfirst dashboard, like who gets notified about calls or connecting my calendar, tell me exactly what to click.

5. Test. Have me call my Upfirst number from my own phone, as a typical customer. Review the transcript with me and fix anything my receptionist got wrong. Repeat until I'm happy.

6. Go live. Help me forward my business line to my Upfirst number using the call forwarding guide. Ask which phone carrier or system I use, and whether I want all calls or just the ones I miss.

Be opinionated. When there's a sensible default, use it and tell me what you chose, instead of asking me to pick between options. Keep your messages short.
