Networking industry giants Cisco and Avaya are being sued bya firm called Klausner Technologies over the inclusion of visual voicemailtechnologies in their solutions.
The suit was filed in the district court of Eastern Texas, which is renownedfor handling technology patent disputes and is currently the focus of a feudbetween Microsoft and i4i.
Klausner alleges that both Cisco and Avaya VoIP solutions haveinfringed on its visual voicemail patents covering features through whichsubscribers can selectively retrieve messages from mobile devices and PCs.
MicroScope understands the mysterious Klausner Technologies,which is owned by PDA and electronic organiser pioneer and inventor JudahKlausner, does not appear to provide any solutions or services itself; itmerely serves as a holder for 25 patents.
Its equally uninformative website provides no clues to theprivately held firm's corporate background or any actual information, merely aseries of email addresses for licensing enquiries.
This is not the first time Klausner has struck, havingpreviously successfully settled with Apple, AT&T, Citrix, Google, LG, and Vonage among others,over similar issues.
Cisco and Avaya have not commented publicly on the spat.
