Phone Numbers
Every hotline needs a phone number. There are two ways to get one — use a platform-provided US number for quick testing, or connect your own number from your Twilio account for production use.
Estimated time: 5 minutes
Which option is right for you?
| Option | Best for | Setup | Countries |
|---|---|---|---|
| Platform number | Testing and evaluation only | One click — no external account needed | 🇺🇸 United States only |
| Your own number (Bring Your Own) | Production use — any country, number belongs to you | ~10 min — requires a Twilio account | Any country Twilio supports |
| Existing number (another carrier) | Keep a number guests already know | Port to Twilio (3–10 days) or forward to a Twilio number (minutes) | Any country |
Use a platform number (testing only)
Enhanced Rentals provisions a US number for you — no Twilio account, no regulatory paperwork. The number is ready within seconds and is intended for testing and evaluating the hotline before you go live.
Open Phone Numbers
In the sidebar, go to Settings → Phone Numbers. You can see all numbers currently provisioned for your workspace and your remaining quota.
Purchase a new number
Click Purchase Number. Select your country from the dropdown and pick from the available numbers. Click Purchase this number to confirm.

Bring your own number (Twilio) — recommended for production
Purchase a number directly from your own Twilio account and connect it to Enhanced Rentals. The number is fully yours — it stays with you regardless of your Enhanced Rentals subscription and can be moved to any provider at any time. The AI hotline works identically to a platform number, with no restriction on country.
Create a Twilio account
Go to twilio.com and sign up for a free account. You can start with a trial account and a trial number for testing at no cost.
Buy the number you want
Inside the Twilio Console, go to Phone Numbers → Buy a Number. Search by country and capabilities (Voice). Select a number and complete any country-specific compliance steps Twilio requires.
Once purchased, the number appears in Phone Numbers → Manage → Active Numbers.
Point the number's webhook to Enhanced Rentals
Open the number in the Twilio Console. Under Voice Configuration → A Call Comes In, set the webhook to:
Replace {your-workspace} with your Enhanced Rentals workspace identifier (the subdomain you created at signup, e.g. mycompany).
Set the HTTP method to POST and save.
Add the number to Enhanced Rentals
In Enhanced Rentals, go to Settings → Phone Numbers and click Add External Number. Enter the number in international format (e.g. +49 30 1234567) and confirm.
The platform verifies the webhook is correctly configured by placing a silent test call. Once confirmed, the number appears in your Phone Numbers list and can be assigned to a hotline.
Already have a number with another carrier
If you have an existing phone number with a traditional carrier or VoIP provider — one your guests already know — you have two paths to connect it to Enhanced Rentals. Both ultimately route calls through Twilio, which is how Enhanced Rentals handles voice.
Port your number to Twilio
RecommendedNumber porting moves your existing number to Twilio's infrastructure. The number stays identical — guests dial the same digits — but Twilio becomes the carrier. Once ported, follow Option B (steps 3 and 4 only) to connect it to Enhanced Rentals.
Initiate the port in Twilio Console
In the Twilio Console, go to Phone Numbers → Port & Host → Port a Number. Enter the number you want to port and follow the wizard. Twilio will ask for a Letter of Authorization (LOA) and your current carrier account details.
Sign the Letter of Authorization
Twilio provides a pre-filled LOA. Sign it and upload any supporting documents your carrier requires (e.g. latest invoice, account number). Your current carrier is notified automatically.
Wait for porting confirmation
Twilio emails you when the port is approved and again when it completes. The number will appear in Phone Numbers → Manage → Active Numbers.
Connect to Enhanced Rentals
Now follow Option B, steps 3 and 4 above: set the Twilio webhook to your Enhanced Rentals workspace URL, then add the number in Settings → Phone Numbers → Add External Number.
Forward calls to a new Twilio number
Immediate — no downtimeBuy a new number on Twilio, connect it to Enhanced Rentals, then configure your existing carrier to forward all incoming calls to that Twilio number. Your guests keep dialling the original number; your carrier silently redirects the call.
Set up a new Twilio number
Follow Option B, steps 1–4 above to create a Twilio account, buy a number, configure the webhook, and add it to Enhanced Rentals. This is your new hotline number.
Enable call forwarding on your existing carrier
Log in to your current carrier's portal and find the call forwarding or unconditional forwarding setting for your existing number. Set it to forward all calls to the new Twilio number you just configured.
The exact steps vary by carrier. Search for “unconditional call forwarding [your carrier name]” or contact their support if you cannot find it.
Test end-to-end
Call your original number from a mobile phone. The call should forward to Twilio and be answered by your Enhanced Rentals AI hotline. Check the call log in Support → Calls to confirm it was received.
Troubleshooting
The Purchase button is greyed out
You have reached your plan's phone number quota. Upgrade your plan or purchase an additional AI Hotline slot from Settings → Billing.
I need a number outside the US
Platform numbers are US-only and intended for testing. For any other country — or for a number that belongs to you in production — use Option B and purchase a number directly from your own Twilio account. Twilio supports local numbers in most countries worldwide.
External number verification fails
Double-check that the webhook URL is set to POST (not GET) and that the URL uses your exact workspace subdomain. The URL is case-sensitive.
Guests say the number is not reachable
Check that the number is assigned to an active hotline with an enabled AI assistant. Unassigned numbers do not answer calls.
My porting request has been pending for more than 10 days
Contact Twilio Support with your port order ID. Delays are usually caused by a mismatch between the LOA details and the information on file with your current carrier — check that the account name and number match exactly.
Call forwarding is set up but calls don't reach the hotline
Confirm the Twilio webhook is configured correctly (Option B, step 3) before testing forwarding. Also check that your carrier is forwarding to the exact Twilio number you registered — even a single digit difference will cause calls to fail silently.
