GEO-REDUNDANT
The world's largest mobile subscriber base sits across three vertically-integrated operators, each with distinct interconnect rules, numbering ranges and acceptance behaviour. Add long-haul transit, MIIT scrutiny and aggressive call-quality monitoring, and most generic wholesale routes show low ASR, high PDD and inconsistent CLI delivery.
MCM solves this with direct mainland interconnects, intelligent Least Cost Routing tuned per operator, and APAC media servers anchored close to the Hong Kong / mainland gateway. The result for wholesale partners: stable Answer-Seizure Ratios on China traffic and predictable per-minute economics across all three networks.

Every China route MCM publishes terminates into one of the three mainland networks. Operations respect MIIT scrutiny, per-operator CLI acceptance rules, and China's national numbering plan — wholesale partners terminate without absorbing the regulatory risk.
No opaque reseller layer between your softswitch and the destination handset. Verified CLI delivered end-to-end on mobile and fixed lines across China Mobile, China Unicom and China Telecom.
Operations respect MIIT scrutiny on cross-border voice — CLI presentation, abandoned-call rules, and per-operator acceptance behaviour are honoured.
Origination respects 86-1 mobile prefixes, city-code geographic numbers, and per-operator allocation ranges.

China Mobile, Unicom and Telecom are scored independently. The moment a corridor drifts, automated rerouting kicks in before wholesale partners feel it on their CDRs.
Geo-distributed media servers across APAC, anchored close to the Hong Kong / mainland gateway. Active-active SIP switching with sub-2-second failover protects against regional outages.
Per-operator economics matter on China termination — China Mobile mobile prefixes are typically priced separately from Unicom and Telecom destinations, and CLI vs Non-CLI splits vary by operator. The three tiers below are the published starting point; an operator-by-operator breakdown is issued in the China rate sheet on request, with further discounts above 1M minutes per month.

Premium retail VoIP, enterprise voice into mainland China.
Negotiated
Guaranteed CLI to China Mobile / Unicom / Telecom on dedicated APAC corridors.
Direct interconnects with the three mainland operators. APAC media servers anchored close to the Hong Kong gateway keep RTP streams short. Active-active SIP switching with sub-2-second failover protects against regional outages.

Standard SIP interconnect. REST APIs for provisioning, dynamic LCR, and real-time CDRs.
Needing direct mainland coverage without resorting to grey routes that fail per-operator CLI checks. Verified, audited, Hong Kong-anchored.
Extending global PSTN reach into Greater China for multinational customers — predictable per-operator economics.
Supplying downstream resellers that demand stable PDD, MOS and CLI delivery on China Mobile and Unicom.
Where the live problem is answer-rate variance between China Mobile, Unicom and Telecom — solved with per-operator routing and quality scoring.
Same-week SIP credentials. Per-operator PDD/ASR baseline before production ramp. Direct China Mobile, Unicom and Telecom — no opaque second-hop reseller layer.
Yes. MCM operates direct interconnects with all three mainland operators. CLI routes deliver verified caller ID end-to-end, and Non-CLI Basic CC routes are available for cost-optimised bulk traffic.
Indicative floors sit at $0.003/minute Basic CC and $0.005/minute Platinum CC. Effective per-minute cost on China traffic depends on operator mix (Mobile / Unicom / Telecom) and CLI / Non-CLI split — a corridor-specific quote is the accurate forecasting number.
APAC-anchored media servers and direct mainland interconnects keep signalling and RTP paths short. Real-time PDD monitoring triggers automatic rerouting if a corridor exceeds quality thresholds.
Yes — verified CLI is delivered end-to-end on Platinum and Custom CLI tiers. CLI presentation behaviour is regulated per-operator, and our routing layer respects each carrier's acceptance rules.
China onboarding adds per-operator due diligence on top of standard KYC, so account approval typically completes in one to two business days. SIP credentials, APAC IP allow-listing and test access to China Mobile, Unicom and Telecom prefixes are issued together. Our APAC carrier desk will run a per-operator PDD/ASR baseline before production ramp.
