US firm Ringadoc said its total seed funding has now reached $1.2 million. It will use the funds to push a new product which enables doctors to manage patient calls from their smartphones.

According to Mobihealthnews, the firm has raised an additional $450,000 in funding which, when combined with $750,000 from last year, brings its total funds to $1.2 million.

The company has also launched its new Ringadoc Exchange product commercially, which has been in beta since August 2012.

The new product enables doctors to better process patients’ calls. Jordan Michaels, Ringadoc’s CEO and co-founder, said the medical profession has relied on “1970s-era technology” to handle their after-hours calls.

In addition to supporting the new product, the funding round will also help develop new patient-facings apps and a premium service that could add video conferencing to the company’s current, voice-based service.
