Hong Kong SAR Wholesale Voice & SIP Peering | AVM Networks

Q: What regulatory framework governs wholesale voice and CLI in Hong Kong?

Wholesale voice in Hong Kong is regulated by the Office of the Communications Authority (OFCA). Under the OFCA Code of Practice on CLI, international incoming calls presenting Hong Kong domestic numbers (+852) are subject to strict anti-spoofing verification. AVM Networks delivers authentic E.164 CLI in full compliance with OFCA standards.

Q: Where does AVM Networks interconnect for Hong Kong traffic?

Interconnection is available via major carrier-neutral facilities including MEGA-i SUNeVision in Chai Wan, Equinix HK data centers, and regional routing hubs, providing low-latency transit towards major destination networks.

Q: What codecs and signaling protocols are supported for Hong Kong SIP termination?

We support G.711a (PCMA), G.711u (PCMU), G.729a/b, and G.722 HD voice over SIP RFC 3261 with TLS 1.3 signaling and SRTP media encryption.

Q: What billing increment applies to Hong Kong wholesale voice routes?

Hong Kong wholesale voice termination is billed on a standard 1/1 second increment on verified conversational traffic.
