Built on DigitalOcean, deployed globally
Our voice infrastructure runs on DigitalOcean's global cloud platform, giving us access to data centres across North America, Europe, Asia Pacific and Africa. Every PoP is purpose-built for voice, with full redundancy and the low-latency routing that carrier-grade voice demands.
- Multiple global PoPs across all major regions
- Fully redundant infrastructure with automatic failover
- Purpose-built FreeSWITCH clusters at every PoP
- G.711, G.729 and Opus codec support throughout
- Real-time monitoring, alerting and incident response
- SIP hardening, Fail2ban and IP whitelisting on all endpoints
Multiple interconnects, superior routing arrangements
Direct interconnect agreements with multiple tier-1 carriers globally gives us the ability to route your traffic intelligently, selecting the best quality, lowest latency path for every call, in real time.
Multiple Tier-1 Interconnects
Direct peering with multiple tier-1 carriers gives us routing flexibility that most wholesale providers cannot match.
Intelligent Least-Cost Routing
ASTPP's LCR engine dynamically selects the optimal route for every call based on quality, cost and latency.
Automatic Failover
If any route or interconnect degrades, traffic shifts automatically to the next best path with zero manual intervention.
Local Proxy Solutions
In-country proxy infrastructure routes calls through local endpoints, presenting as domestic origination for maximum answer rates.

Whether you are running a predictive dialer campaign for 500 agents, an AI bot army making tens of thousands of simultaneous calls, or a carrier interconnect carrying bilateral traffic, our infrastructure handles it without a conversation, without a ticket, without a wait.
Discuss Your Volume NeedsA real carrier switch, not just billing software
ASTPP is a full carrier-grade Class 4 switching platform. It handles real-time routing decisions, least-cost routing logic, rate deck management, CDR generation, prepay and postpay billing, and full reseller management, all in one platform. This is the same technology tier-1 carriers use.
Unlike most wholesale providers who layer billing on top of a basic switch, ASTPP gives you true Class 4 switching — real-time decisions, priority-based routing, and complete visibility of every call through granular CDRs. You get carrier-grade control without carrier-grade complexity.
We also offer standalone ASTPP consultation and implementation services for carriers and businesses looking to build or optimise their own Class 4 switch infrastructure. Our engineers have deployed and managed ASTPP clusters at scale — we know the platform inside out.
