Infratel, a company that provides a range of cloud telephone services for small businesses, has raised $3 million in Series A funding in a round led by a duo of Russian venture capital firms: Prostor Capital and Runa Capital.

The firm says it will use the fresh cash to expand its platform and increase its presence globally.

Infratel integrates directly with a provider’s infrastructure, enabling its small business clients to more effectively handle interactions with their customers over the phone.

The company’s solutions include a ‘Cloud Receptionist’ virtual phone system, an accompanying Facebook app, a way to create and manage voice-based ad campaigns and a product dubbed ClickConnect, which lets customers add click-to-call capabilities to their websites.

The company says it has more than 1,000 customers worldwide and helped customers manage 1 billion minutes of calls in 2011.

Infratel is privately held and headquartered in Seattle, Washington.
