Jajah is a web-based service that allows users to place VoIP calls through the company's website. Customers enter their own and the recipient's phone number, at which point the Jajah service dials both numbers and connects the call.
The investment was made through Intel Capital, the company's venture capital branch, and was one of six investments announced by the company totalling $31m.
Jajah hopes that the deal will allow it to expand its services beyond web-based calling into the broader telecoms market.
"All voice communication will soon be IP-based," declared company co-founder Daniel Mattes.
"Phones are quickly turning into computers, and computers are quickly turning into phones. We need to marry them in a fundamental way."
Jajah will also receive access to several Intel telephony patents. The company hopes that this will ultimately lead to VoIP-enabled processors.
"The deeper Jajah can be embedded into Intel solutions, the better for customers everywhere," said Jajah co-founder Roman Scharf.
"It is our intention to bring a best-of-class, next-generation solution to the market which can be embedded and optimised for any computing device."
