How can we help?

Create your customer account, confirm the services and rates you need, fund your balance through the available PayPal options, and configure your number and calling device. Service activation and number availability are confirmed separately.

Check your internet connection, SIP username, password and assigned server. Use the SIP credentials for your calling account, which can differ from your customer portal login. Avoid repeatedly guessing passwords. If registration still fails, contact support with your device model and the error shown. Never include passwords in a support form.

Check that the incoming number is routed to the intended destination and that the device is registered to the assigned server. Review opening hours, forwarding, ring groups and voicemail routing. Give support the called number and an example time so the route can be checked.

Try another network or device to narrow down the problem. Check Wi-Fi signal and internet stability, and review the device’s network settings with support. Provide an example call time, affected number and whether the problem affects incoming, outgoing or all calls.

A forwarded call uses an incoming call leg and an outgoing call to the destination. The incoming charge follows your number plan; the destination’s outgoing rate also applies for the call duration. Check both rates before forwarding to international or mobile destinations.

A universal signup credit has not been confirmed or enabled. Any credit shown in a test or pilot account should not be assumed to be an offer for every customer. Only rely on a promotion expressly confirmed by 37D.

Customer billing is in USD and uses PayPal. Check your confirmed customer rates and account balance before using services. Number rental, usage, forwarding, messaging and paid add-ons can have separate charges. Contact support if a payment does not appear in your balance.

Available self-service options depend on your account and portal configuration. A new number and a SIP extension are different: the number receives incoming calls, while the extension connects a phone or application. Contact support to confirm ordering permissions, availability and pricing.

Messaging depends on the country, number type, enabled services and applicable registration requirements. A working voice number does not automatically guarantee messaging support. Ask support to verify eligibility and registration before sending business messages.

AI receptionist service requires separate activation, pricing approval and configuration. Prepare your business greeting, hours, answers to common questions and transfer destinations. A feature page or prepared agent does not mean the paid service is active on your number.

A dedicated 37D Connect mobile app is planned and is not yet available for download. Compatible SIP applications can connect to a configured calling account. Support can confirm suitable connection settings for your device.

Include the type of issue, affected number, approximate date and time with timezone, device or app name, error text and steps you have tried. For call problems, say whether incoming or outgoing calls are affected. Do not send passwords or payment-card details.
