Just to be more specific , i need to develop a Walkie-talkie app , is it require an SIP server ? – Ashraf Feb 27 '12 at 16:29
Well, you'll have to provide one way of initiating VoIP session. I'm not saying SIP is the only way but it's most often used thesedays. If your application will work only for phones in BT range (or in same WiFi) you could probably use bonjour for this purpose. – Rok Jarc Feb 27 '12 at 16:39
