How to call Antarctica from your platform
Dial Antarctica numbers in E.164 format: country code +6721 followed by the national number, with no local trunk prefix, spaces or brackets. Most platforms expect digits only; some require a leading plus. Confirm the exact dial pattern during testing.
CloudyVoice works with any SIP-capable endpoint — softphones, IP desk phones and ATAs, IP-PBX platforms such as Asterisk, FreeSWITCH and 3CX, call-centre dialers including ViciDial, and VOS softswitch deployments. Authentication is by SIP registration or approved IP address.
Before sending production traffic to Antarctica, test across several networks in the destination and check two-way audio, caller ID behaviour, post-dial delay, answer supervision and billing. The route-quality guide explains the method.
