Before you start
- A SIP user created in the portal with an authorised caller ID.
- Zoiper 5 installed from the official site or app store.
Placeholders in angle brackets, such as <ACCOUNT_ID>, come from your portal. The host shown is a placeholder; use the one listed under Portal → Network.

Test calls
Call a mobile and a fixed line in the destination country, as country code plus number. Check the caller ID shown and listen for audio in both directions. On mobile, repeat on Wi-Fi and on mobile data.
Mobile networks and battery
Mobile operating systems suspend background apps, which drops SIP registrations. Zoiper offers push notifications in its paid edition to receive inbound calls while in the background. For outbound-only testing, keep the app in the foreground.
