China Wholesale Voice & SIP Peering | AVM Networks

Q: How does AVM Networks handle wholesale voice termination into mainland China?

Because Chinese regulations reserve domestic telecom operations for licensed national state-owned carriers, AVM Networks terminates international traffic via bilateral interconnects with licensed international gateway carriers—including international entities of China Telecom, China Mobile, and China Unicom—peering through high-capacity regional hubs in Hong Kong (Equinix HK1, Mega-i) and Singapore.

Q: What regulatory framework governs international voice termination into China (+86)?

Voice traffic into mainland China is governed by the Ministry of Industry and Information Technology (MIIT) and the Anti-Telecom and Online Fraud Law of the PRC (effective Dec 1, 2022). Telecommunications service providers must ensure clean E.164 caller identification, with strict zero-tolerance enforcement against CLI spoofing, illegal cross-border bypass, and unauthorized autodialing.

Q: What billing increments and rating models apply to China wholesale SIP routes?

International wholesale voice termination to China is conventionally priced on a 60/60 second billing increment. Rates are segmented into major geographic metropolitan centers (Beijing, Shanghai, Guangzhou, Shenzhen), provincial fixed lines, and nationwide mobile operator ranges.

Q: How is Caller ID (CLI) verified and handled for calls into China?

All inbound international calls terminating into mainland China (+86) must carry authentic, non-manipulated E.164 Caller Line Identification corresponding to the verified originating subscriber or enterprise DID. Domestic Chinese numbers originating from overseas networks without authorized enterprise documentation are rejected by gateway anti-fraud filters.

Q: What codecs and transport protocols are recommended for China wholesale SIP trunks?

We recommend G.711a (PCMA) or G.729a codecs over RFC 3261 SIP v2.0 signaling. For secure signaling and media transmission, TLS 1.2/1.3 and SRTP are supported at our Hong Kong and Singapore regional peering nodes.

AVM Networks Carrier Engineering Team

China Wholesale SIP Trunking & Carrier Voice Termination

AVM Networks Limited delivers enterprise wholesale SIP trunking and bilateral voice peering into mainland China (+86). Because domestic telecommunications networks in China are governed by state licensing rules and operated by licensed national carriers, AVM Networks routes inbound international traffic through direct bilateral interconnects with licensed international gateway carriers—including international divisions of China Telecom, China Mobile, and China Unicom—via regional peering hubs in Hong Kong (Equinix HK1, Mega-i) and Singapore. Engineered for multinational corporations, enterprise contact centers, and financial institutions, our China voice corridor enforces authentic E.164 CLI pass-through, low Post Dial Delay, and rigorous compliance with the Anti-Telecom and Online Fraud Law of the People's Republic of China.
