Yes, I enabled logging, however, no additional logging was available.
I instrumented the code myself with additional logging. I have provided the
code snipet
from chan_dahdi.c below. It appears that my problem is caused by the TDM
channel being
in the Onhook state. Something makes the channel go Offhook, and things begin
to work
properly. I'm able to solve the Onhook case by changing the code to always
return 1
when Onhook, indicating Offhook.
I'm hoping someone might shed some light on the "onhook" comments here. What
causes both
par.rxbits == -1 and par.rxisoffhook == 0?
chan_dahdi.c line 3786
if (res) {
ast_log(LOG_WARNING, "Unable to check hook state on channel %d: %s\n",
p->channel, strerror(errno));
} else if ((p->sig == SIG_FXSKS) || (p->sig == SIG_FXSGS)) {
/* When "onhook" that means no battery on the line, and thus
it is out of service..., if it's on a TDM card... If it's a channel
bank, there is no telling... */
if (par.rxbits > -1)
return 1;
if (par.rxisoffhook)
return 1;
else {
ast_log(LOG_WARNING, "available 6c par.rxbits: %d par.rxisoffhook:
%d\n", par.rxbits, par.rxisoffhook);
// return 0;
return 1;
}
