A few things
to know.

Ask our team
Where can I get a phone number?+

Open Phone Numbers in the portal and select a country. The catalog shows the available number types and inventory for that location. Availability changes, so check the current catalog before planning your setup.

Will my number activate immediately?+

Activation depends on the destination and its registration requirements. Some numbers require supporting documents and approval before they become active. Check the order status in your account.

Can every number receive SMS?+

SMS availability depends on the number and destination. Confirm the capabilities of your chosen number before using it for messaging.

Can I use a number with my existing PBX?+

Yes. Incoming routing includes external SIP servers and SIP URI, as well as local SIP users. You can configure the destination from your number’s settings.

How is a phone number billed?+

Review the setup fee, monthly rental and applicable usage charges for your selected number. The portal notes that monthly recurring charges are prorated for the remainder of the current billing cycle and billed in advance for the next cycle.

Is verifying my existing caller ID the same as porting?+

No. External caller ID verification lets you verify a number you own for outbound caller ID. Porting is a separate request to move the number to IllyVoIP. Verifying caller ID alone does not move its incoming calls.

Can I pay for a phone number with cryptocurrency?+

Yes. Top up your IllyVoIP balance using a supported cryptocurrency, then use your balance to order a number. Availability, identity verification and any country-specific document requirements still apply.
