Incoming call accepted, Status = call!

[indotronic]

if incoming call accepted, cannot get cancel if caller hang up the call.

[rousir]

If the call is answered, send call hang up command to hang up the phone

void SipMachine::bye()
{
    sipBye();
    status = idle;
}

If the caller cancels the call, esp32 will reset the state after receiving the bye command

ArduinoVoip/src/SipHeader.cpp

Line 40 in d09927c

if (in.indexOf("BYE sip:") > -1)

ArduinoVoip/src/SipMachine.cpp

Line 283 in d09927c

case 1:

[indotronic]

If the caller cancels the call :

ArduinoVoip/src/SipMachine.cpp

Line 122 in d09927c

if ((status == call) & (timeStOut % 20000 == 0))

if caller calling and answered, speak, and caller hang up. Esp no get respondcode, still lopoping in here!

[indotronic]

and if time experied the sip cannot re-registering!

[rousir]

Okay, I didn’t encounter this problem during the test. I have been busy recently. I will check it when I have time.
The sip protocol is simple, you can use the debug information to check that the step was unsuccessful

[indotronic]

Ok,
fix now for re registering issues!

pls see the code

ArduinoVoip/src/SipMachine.cpp

Line 190 in d09927c

if (sipHeader.contentLength < 0)

its on if condition
if (sipHeader.contentLength > 0)
{

}

its work?

[rousir]

if (sipHeader.contentLength > 0)
{
    sipHeader.contentLength -= (str.length() + 1);
    debugL1_println(str.c_str());
    parserSdp(str);

    if (sipHeader.contentLength < 0)
    {
        exec();

        if (status == messageIn) {
            debugL1_println(str.c_str());
            messageData = str;
        }
    }
}

It works and is used to detect the content of the sip body

[rousir]

After receiving the call, esp needs to send the answer command many times to answer it normally?
收到呼叫后，esp需要发很多次接听命令才能正常接听？

[indotronic]

i think esp no send command many time..
and auto hangup after 10sec accept call

[indotronic]

the call problem ended outomatic after 10 second solved.. but if caller hang up, caller not send BYE..

[indotronic]

if make call not work, just show
