What additional equipment/apps do I need to acquire/install in order to use 7921G phone with my commercial VoIP provider - broadvoice.
It looks like I can easily connect this baby to my Aironet AP-1231 wireless access point. Will I be able to just set up SIP parameters in the phone without any additional equipment? What if I want to hook up a couple of these phones - what would I need in order to do that? Some sort of additional box running asterisk or something?
