Hi, I am trying to execute PJSIP application in symbian s60 emulator with carbide c++. I installed asterisk server and it is running in one machine and the IP is 192.168.64.106 and the port is 5060. My PJSIP application is installed in another machine (IP : 192.168.64.112)and the parameters which i given in the ua.cpp file is, SIP_PORT 5060 SIP_DST_URI "sip:192.168.64.106:5060" #define HAS_SIP_ACCOUNT 1 #define SIP_DOMAIN "192.168.64.112" #define SIP_USER "" #define SIP_PASSWD "" #define SIP_PROXY "sip:192.168.64.106" #define NAMESERVER NULL # define STUN_DOMAIN NULL # define STUN_SERVER "stun.fwdnet.net" # define STUN_DOMAIN "xten.com" # define STUN_SERVER "stun.xten.com" # define STUN_DOMAIN NULL # define STUN_SERVER NULL Emulator is shutting down immediately. I am not able to proceed further. I got the following errors in the emulator.*"Error contacting STUN server " : Received no response from STUN server (PJLIB_UTIL_ESTUNNORESPOND)* *"Error creating transport" : Received no response from STUN server (PJLIB_UTIL_ESTUNNORESPOND)* what parameters should i give in the STUN_DOMAIN & STUN_SERVER. Please help me. Thanks in advance, sans -------------- next part -------------- An HTML attachment was scrubbed...
