Could anyone kindly help me with following 4 issues? 1.For serverless configuration: receiver: $ ./pjsua caller: $ ./pjsua sip:192.168.0.10 For this serverless case, I feel they can only communicate in intranet enviroment. My question is : can they be used in internet enviroment? If yes, how can they find peers? If not, how to configure them for internet communication? 2. For Registering with SIP Provider: $ ./pjsua --id sip:alice at example.com --registrar sip:example.com \ --realm * --username alice --password secret Could you tell me where to get the SIP Provider? Is there any source code of such a provider. 3. If can we use a STun server as follows? $ ./pjsua --id sip:alice at example.com --registrar sip:example.com \ --realm * --username alice --password secret --stun-srv=stun_server_ip where stun_server_ip is the internet ip address of that sample server: pjstun-srv-test-i386-win32-vc8-debug.exe 4. Could SIP provider and Stun server locate at one physical machine? I'm looking forward to your help.
