About VOLTA
Building the voice layer other operators rely on
VOLTA is an independent carrier headquartered in Riga, Latvia, operating a fully owned international voice core across 24 points of presence. We interconnect mobile network operators, fixed incumbents, MVNOs, aggregators and enterprises in more than 190 countries — carrying conversations that have to arrive with the right caller identity, the right audio quality and the right economics, every single time.

Company history
From one softswitch pair to a global voice core
volta.network was built by engineers who believed wholesale voice was being sold as a commodity when it should have been engineered as infrastructure. That conviction — that route quality is a design problem, not a purchasing problem — still governs how we build.
Phase 01
Founded in Riga
A group of core-network engineers incorporate VOLTA to wholesale surplus Baltic transit capacity. The first international minute is switched on a single softswitch pair in a Riga colocation suite.
1 PoP · 3 interconnects
Phase 02
Western European backbone
VOLTA lights protected capacity into London, Frankfurt and Amsterdam, joins LINX and DE-CIX, and signs its first tier-one bilateral agreements for premium CLI-guaranteed termination.
4 PoPs · 60 carrier partners
Phase 03
Transatlantic expansion
New York and Miami switching centres open, extending A-Z termination into the Americas and unlocking Latin American mobile destinations through direct operator interconnects rather than resold routes.
9 PoPs · 4.2bn minutes
Phase 04
Cloud communications platform
VOLTA launches its CPaaS layer — programmable voice, SMS and global DID provisioning — moving the company from pure wholesale into enterprise SIP trunking and hosted voice.
First 10,000 API customers
Phase 05
Asia-Pacific and Gulf build-out
Singapore, Hong Kong, Tokyo, Sydney and Dubai enter service on a fully redundant MPLS core, with regional SBC clusters delivering sub-40 ms post-dial delay across the corridor.
18 PoPs · 5 continents
Phase 06
AI-assisted fraud and quality control
Real-time machine-learning models score every call attempt for SIM-box, Wangiri and traffic-pumping patterns, cutting confirmed fraud loss across the customer base by 82 percent.
99.999% availability sustained
Phase 07
The next corridor
Construction begins on additional edge sites in Lagos, Mumbai and São Paulo alongside new subsea capacity commitments, extending guaranteed-quality routes deeper into high-growth mobile markets.
24 PoPs · 190+ countries
Our mission
To make international voice behave like critical infrastructure rather than a marketplace. Every route we sell is one we operate, monitor and are accountable for. We publish the quality metrics that matter — answer-seizure ratio, average call duration, post-dial delay and CLI delivery — and we hold ourselves to them contractually. Our customers should be able to launch a service in a new market without first having to become experts in that market's termination politics.
Our vision
A world where a call between any two people is authenticated end to end, priced transparently and delivered at the quality of a local connection. We are building toward a fully programmable carrier: every route, number, policy and settlement exposed through an API, with fraud intercepted before the first ring and identity verified before the first word.

Leadership
Operators, not administrators
VOLTA's executive team has built switching cores, negotiated bilateral agreements, run NOC escalations at three in the morning and closed settlement disputes across forty currencies. Two of the six co-founded the company.
Elīna Bērziņa
Chief Executive Officer
Co-founder. A career in international voice, previously head of wholesale settlements at the Latvian incumbent. Leads VOLTA's commercial strategy and carrier board relationships.
Marcus Feldt
Chief Technology Officer
Architect of the VOLTA MPLS core and SBC estate. Former principal engineer on two transatlantic subsea systems; chairs the company's network reliability council.
Priya Raghunathan
Chief Commercial Officer
Runs global wholesale trading and the 800-partner interconnect programme, with prior tenure building APAC mobile termination portfolios at a tier-one carrier.
Tomasz Wójcik
SVP Network Operations
Owns the follow-the-sun NOC in Riga, Dallas and Singapore, the change-management regime and the five-nines availability commitment written into customer SLAs.
Sofia Almeida
Chief Financial Officer
Directs treasury, settlement risk and capital planning across 40 billing currencies, and led the refinancing that funded the Asia-Pacific expansion.
Daniel Okonkwo
SVP Regulatory & Compliance
Manages licensing across 31 jurisdictions, STIR/SHAKEN and CLI integrity programmes, GDPR governance and lawful-intercept obligations.
Subsea capacity commitments on four cable systems
Global expansion
Growth measured in interconnects, not offices
Expansion at VOLTA follows traffic, not fashion. A region qualifies for a switching centre when our customers already terminate enough minutes there that owning the interconnect improves quality and margin simultaneously.
That discipline took us from the Baltics to Western Europe, then to North America, and on to Asia-Pacific and the Gulf. Each new site opens with local regulatory licensing, at least three diverse upstream paths, a regional SBC cluster and named operator relationships in market — never resold capacity dressed as direct routes. In the next phase we are extending the same model into West Africa, South Asia and Brazil, where mobile growth is outpacing the quality of available wholesale supply.

Traffic moving across the VOLTA footprint
Twenty interconnect facilities, continuously switching international voice between Tier-1 exchanges. Hover any node to inspect the carrier, latency, spare capacity and the routes it is currently feeding.
Carrier relationships
Eight hundred partners, one standard of accountability
Our interconnect portfolio spans tier-one international carriers, national incumbents, mobile network operators and specialist regional aggregators — but every partner is measured against the same scorecard.
Bilateral first
Wherever volume justifies it we hold direct bilateral agreements with the terminating operator. Direct relationships mean genuine CLI delivery, predictable surcharge behaviour and an engineer to call when a destination degrades — rather than three intermediaries denying responsibility.
Continuous scoring
Every partner route is probed and rated around the clock. Quality regressions trigger automatic re-routing and a commercial review; sustained under-performance removes a supplier from premium profiles entirely, regardless of price advantage.
Settlement integrity
Bilateral netting, escrowed prepayment options and daily reconciliation against mediated CDRs keep disputes rare and short. Partners see the same rate, quality and dispute data through our portal that our own trading desk works from.
Technology stack
Engineered end to end, owned end to end
VOLTA operates its own switching, transport, routing intelligence and security layers. Nothing critical to call quality is outsourced, because nothing outsourced can be guaranteed.
Carrier switching core
Redundant class-4 softswitch clusters with geographically paired session border controllers handle 1.4 million concurrent sessions, transcoding G.711, G.729, AMR-WB and Opus at the edge.
Transport and peering
Protected DWDM waves between switching centres, diverse subsea paths on four cable systems, and settlement-free peering at fifteen major internet exchanges.
Routing intelligence
A least-cost routing engine re-scores every destination on ASR, ACD, PDD and CLI delivery every sixty seconds, moving traffic away from degrading routes before customers notice.
Security and assurance
TLS and SRTP encryption, STIR/SHAKEN attestation, ISO 27001 controls and machine-learning fraud scoring applied to every call attempt in real time.
Network infrastructure — 2N power, concurrently maintainable
Network infrastructure
The VOLTA core is a dual-plane MPLS network with no single point of failure between any two switching centres. Media and signalling are separated, SBCs are deployed in active-active pairs across distinct power domains, and every site can absorb the full session load of its regional partner during maintenance or failure. Capacity is provisioned to a hard ceiling of sixty percent peak utilisation, so a complete regional outage never translates into congestion for customers elsewhere. Change windows are governed by a formal review board, and every configuration change is version-controlled, peer-approved and automatically rollback-tested before it reaches production.
Data centres
We deploy exclusively into carrier-neutral Tier III and Tier IV facilities with 2N power, concurrent maintainability and rich local interconnect ecosystems.
