I need a Sip server to build a VIOP server to establish voice call between 500 Android an desktop sip clients.
Can Kamailio handle this or I need an Asterisk server too?
Answer
Kamailio is only an SIP proxy (call negotiation), you still need a RTP server in order to handle the audio of the calls like Asterisk or FreeSwitch
