Frequently asked questions

IDNTEL is communication identity infrastructure that turns readable domain identities into entries for telephone, voice and other communication services. Domain Phone is a slogan, not a second brand.

The story is: IDNTEL → Communication Identity → T2N (Text-to-Number) → Communication Entry → Route Type → Communication. 00cctel is a concrete T2N entry (00 + CC + tel). Route Type decides which communication service is entered. 302tel.com is a technical access host.

After visiting a readable domain, you can enter the matching telephone or voice communication. Some access methods use CNAME and Telephone Routing (the implementation may include HTTP 302). Before you begin, confirm:

• Your domain is active, DNS is configured, and the redirect rule is in place
• The target mobile number is formatted correctly (international numbers supported)
• Your domain is active at your registrar (identity and renewal are managed there)
• Your platform supports 302 redirects to tel: URIs

We do not register or host customer domains. Add DNS at your registrar, then complete binding on this site. Steps:

1. Confirm you legally own the domain and it is active at your registrar
2. Add a CNAME record pointing to 302tel.com in your registrar's DNS panel
3. Sign in / Register here, submit the domain and mobile number, and complete verification
4. After DNS propagates, visiting the domain should open the dialer

On this site, follow the CNAME tutorial to point your domain to 302tel.com and complete binding here. For phone verification, see the Phone verification guide.

Costs usually fall into two parts:

• Domain registration: purchased and renewed at your registrar; fees vary by TLD
• Binding on this site: only the trial is free. Paid activation and renewals follow what your account page shows (this page does not lock an amount or payment rail).

Trial: trial page. Sign-up, payment, and renewal: Sign in / Register, then your account portal.

We offer one unified Domain Phone binding service (available during trial or paid year), including:

• Domain CNAME access and Telephone Routing (some implementations use HTTP 302)
• Binding status and redirect management
• Multiple domains per account (different numbers per domain)
• Automatic international number formatting

Except for trial, self-service customers must pay the annual fee to continue. There is no “free basic” vs “premium” split.

The trial is free. Paid activation and renewals follow what is shown after sign-in in your account. This page does not lock an amount or payment rail.

Yes. The platform supports multi-domain management:

• Assign different target numbers per domain
• Batch edit, pause, or enable redirect rules
• View status and traffic across domains in one place

In a mobile browser:

1. The browser receives an HTTP 302 redirect
2. It navigates to a tel:number URI
3. The dialer opens with your target number; the user taps call to connect

Some browsers may ask the user to confirm opening the dialer.

Two phases:

• DNS propagation: usually minutes to a few hours, depending on registrar and local cache
• Redirect rule on our platform: often within 1–5 minutes after you save

Global full propagation rarely exceeds 24 hours.

In the customer portal you can:

• Update the target mobile number
• Enable or pause redirects per domain
• View your account and service renewal status on this site

Portal entry: Sign in / Register.

Yes, but two kinds of expiry matter:

• Domain expiry: renew at your registrar; if the domain lapses, DNS fails and the redirect stops (we do not manage domain renewals)
• Service expiry on this site: redirect stops if the annual fee is not renewed; renew to restore (no downgrade tier)

We send reminder emails before our service expires when your contact email is on file.

Common causes:

• Domain expired; DNS no longer resolves
• DNS records changed or removed
• Redirect rule edited or paused by mistake
• Registry lock or suspension
• Browser or carrier blocking tel: handoff (e.g. in-app browsers)

Check domain and service status in the portal, or contact support.

Legitimate use is usually fine. Blocks are more likely when:

• The domain is flagged as spam or phishing
• The target number is heavily reported
• In-app browsers (e.g. WeChat) restrict direct dialer jumps

We continuously improve delivery. Some in-app browsers (e.g. WeChat) may not open the dialer directly — that is a platform limitation.

We support mobile numbers worldwide. Include the correct country calling code (e.g. +86 China, +1 US, +852 Hong Kong); the system normalizes formatting where possible.

When the domain expires at your registrar, DNS and redirect stop. If you renew there and restore DNS, binding on this site usually still works. Stored binding config is typically kept for 30 days; if DNS is healthy again within that window, service can resume. After 30 days without recovery, config may be deleted and you may need to bind again.

In the portal under domain management, edit the target number for each domain. Changes typically apply within 1–5 minutes without DNS changes. Multi-domain accounts can batch-update targets.

HTTP 302 is a standard temporary redirect and does not by itself penalize domain reputation. If the hostname has no real web content and only triggers dialing, search engines may not index it meaningfully — do not expect SEO benefit from dial-only use.
