Hello,

I have 2 pieces of code  (one written in Python and other in C) that use
Gammu to wait for a incoming call and when a callback function is called
this function just save some info and call GSM_CancelCall.

When running the Python version, the Incoming Event callback is called and
I call the object method sm.CancelCall(0,True). Everything happens as
expected.
The call is canceled right away.

On the other hand, when I invoke the GSM_CancelCall on the C code, inside
the Incoming Event callback I get the error:

*Function not supported by phone.*

I found that GSM_CancelCall calls the function:

s->Phone <http://gammu.sourcearchive.com/documentation/1.29.93-1/struct__GSM__StateMachine_a059ab31e4b6106f281acf8b405f205ff.html#a059ab31e4b6106f281acf8b405f205ff>.Functions
<http://gammu.sourcearchive.com/documentation/1.29.93-1/structGSM__Phone_a0f00f418db11f98347f89d84d9d6b53e.html#a0f00f418db11f98347f89d84d9d6b53e>->CancelCall
<http://gammu.sourcearchive.com/documentation/1.29.93-1/structGSM__Phone__Functions_a75308edd52c239e912cc91530122c000.html#a75308edd52c239e912cc91530122c000>

Where s is a pointer of type GSM_StateMachine and is passed as
argument to the callback function.
Looking at the pointers values in the *GSM_StateMachine *s* received
as parameter of the Incoming Call Callback function.
I found the s->Phone.Functions pointer == NULL.

The question is: Why the code work on the Python implementation that
calls GSM_CancelCall and not on the native C code?

I tested in 2 different devices: a Samsung GT-E2220 and a Motorola
EX108, in both devices I got the same results.

Below is the function CancelCall of the Python object retrieved from
the gammu/src/gammu.c of the python-gammu repository where a I found
the same call that I do in my code:


static PyObject *
StateMachine_CancelCall(StateMachineObject *self, PyObject *args,
PyObject *kwds) {
    GSM_Error           error;
    static char         *kwlist[] = {"ID", "All", NULL};
    int                 id;
    gboolean                all;
    PyObject            *o = Py_None;

    if (!PyArg_ParseTupleAndKeywords(args, kwds, "iO", kwlist,
                &id, &o))
        return NULL;

    all = BoolFromPython(o, "All");
    if (all == BOOL_INVALID) {
        return NULL;
    }

    BEGIN_PHONE_COMM
    error = *GSM_CancelCall(self->s, id, all);*
    END_PHONE_COMM

    if (!checkError(error, "CancelCall")) return NULL;

    Py_RETURN_NONE;
}

Below is the debug information while running my C application:
