Cisco (NSDQ: CSCO) is expanding its software offerings with the acquisition of Jabber Inc., a provider of enterprise IM and presence services. The Denver company bases its technology on the Jabber protocol, which also powers consumer IM services. Cisco notes that the technology allows companies to manage consumer IM apps (AIM, Google (NSDQ: GOOG) Talk) in a manner appropriate for the enterprise. But this will not be part of Cisco’s consumer offerings, rather it will be part of its Collaboration Software Group (CSG). Terms of the deal, which is expected to close in the first half of next year, were not disclosed. Release.
