both ways.

Questions before
your first call
What is the difference between outbound and inbound?
Outbound calls start from your business and go to customers. Inbound calls start from customers and arrive at your business number. SIP routes handle outgoing connectivity; DID numbers provide an incoming destination.
Can the same number support calls in both directions?
Where supported, an inbound DID can also be used as authorized outbound caller ID. Availability depends on the country, number type and route. Ask us to confirm the configuration and test both directions.
Can I connect my existing phone system?
Share the details of your SIP-compatible PBX, contact centre or calling platform. Our team can help confirm connection settings, supported codecs and the configuration needed for your traffic.
Do CLI and Non-CLI routes work the same way?
No. CLI routes support caller ID presentation subject to route and destination requirements. Non-CLI routes do not guarantee caller ID. We help choose an appropriate option for your authorized traffic.
How do I get current rates and number availability?
Send us the countries you call, the countries where you need numbers, expected volumes and capacity. We will discuss suitable routes, DID options and commercial terms.
Can I test before launching?
Yes. AOneVoIP offers free SIP route testing. Agree the test scope with our team, including any DID provisioning or inbound requirements, before proceeding.
