I am new to all this VOIP so maybe my question is a bit stupid.
Looking into the feature list of a Cisco SPA 502G it says "1 line"? I want to connect this phone to my Switchvox AA65 which then handles connections to SIP providers. Does it mean that I can only handle one call at a time and can not e.g. do a 3-way conference, or does it mean that I can only register the phone with one single SIP server but have unlimited connection with this server?
Thanks for your help!
