I am new to voip and am not sure what application it can be used for, but I am looking to set up a 2 way intercom system over a network. Where each user has a choice of a push to talk button or an open line of communication. Can this be done using Asterisk? or does anyone know if there is a better way to do this?
absolutely Asterisk can be used an intercom for one or many different users at once. Our company uses Asterisk as a central bridge and we Push to Talk with our VS-71 SIP Devices. See our web site at www.essentialtel.com.
