나 SIP 서버로 INVITE 보내려고 :GCDAsyncSocket 전송할 SIP 패킷
GCDAsyncSocket *outgoingCallSocket = [[GCDAsyncSocket alloc] initWithDelegate:self delegateQueue:socketOutgoingCallQueue];
BOOL result = [outgoingCallSocket connectToHost:currentSoftswitch.ip onPort:5060 error:&error];
- (void)socket:(GCDAsyncSocket *)sock didReadData:(NSData *)data withTag:(long)tag
- (void)socket:(GCDAsyncSocket *)sock didConnectToHost:(NSString *)host port:(uint16_t)port;
{
NSLog(@"Connected socket to %@:%hu", host, port);
[sock writeData:finalData withTimeout:-1 tag:OUTGOING_CALL];
NSLog(@"\n===================SEND START TO currentSoftswitch.ip->%@:5060 =================\n%@\n===================SEND FINISH=================\n",host,[[NSString alloc] initWithData:finalData encoding:NSUTF8StringEncoding]);
초래할 것이다 :
> ===================SEND START TO currentSoftswitch.ip->195.26.84.147:5060 ================= INVITE

하지만 whireshark를 체크인하면 패킷이 SIP처럼 감지되지 않습니다. 내가 틀렸어?
왜 2 개의 소켓 객체를 사용합니까? 특별한 이유가 있니? –
