[Asterisk-biz] Sprint Nextel sueing over VoIP patents

[Sergey Kuznetsov]

Therefore if you are using an ordinary SIP-phone, you are avoiding the 
patent infringement.

I cannot understand why Sprint sues the Vonage?
They suppose to sue The Cisco-Linksys-Sipura company et al. who is 
actually develop those devices.


All the Best!
Sergey.
