Vistula works in partnership with telecommunications companies worldwide to deliver voice traffic reliably and cost-effectively on simple trade terms and via direct correspondent relationships.

We offer constant and committed capacity across all networks, with carrier-grade quality transport on both switched-circuit minutes and VoIP. In fact, we use superior Lucent and SONAS switches which, with their current configurations, are capable of carrying in excess of 200 million minutes.

Plus, all direct correspondent routes are backed up by target ASRs at carrier-grade level or beyond, and Vistula’s flexibility on collection means you have a choice of landing traffic either in the USA or the UK.

Vistula’s international voice services are designed to meet the most challenging needs for capacity. This allows you to enhance voice margins through high-quality, low-priced service without having to commit to investment in infrastructure at the network level. And with our generous credit terms for Tier-1 carriers, we can help you manage your cash flow more effectively.
