Gaithersburg, Maryland-based Broadsoft said this week that it has signed a definitive agreement to acquire the assets of Campbell-based Casabi. The deal is worth approximately $1.95M. Casabi is a developer of software applications to help provide users send group text messages, access voicemail, and manage their personal calendars, targeted at broadband and telecom providers.

Casabi had raised over $21.5M in funding from firms such as Canaan Partners, Great Pacific Capital, Mayfield, and Vanguard Venture Partners.
