Summary:                    different 'ringt' timeout counting styles througout
chan_dahdi/sig_analog code
Description: 
Below are the three styles I've found.
All trying to achive very close to the same thing, to timeout 'ringt'.
<pre>
<u>Style 1:</u>
if (analog_p->ringt) {
    analog_p->ringt--;
}
if (analog_p->ringt == 1) {
    return -1;
}

<u>Style 2:</u>
if (p->ringt)
   p->ringt--;
   if (p->ringt == 1) {
       res = -1;
       break;
   }
}

<u>Style 3:</u>
if (p->ringt == 1) {
    ast_mutex_unlock(&p->lock);
    return NULL;
}
else if (p->ringt > 0)
    p->ringt--;
</pre>
