Jim use core set verbose 7 see http://ohnosec.org/drupal/node/176 for meaning of the signals If you leave the COS on, you may time out the machine, which can lead to confusing results. And - if the machine wakes up with the COS on, I think that blocks the transmit until you toggle it off once.

I've been following http://www.qsl.net/k0kn/cm108_mod.html Can anyone advise if there's a way to determine from the Asterisk side if COS is active or not? I've even tried manually taking the CM108 pin 48 to 0v and +5v with the iax.conf below, but I can't seem to make anything 'happen'. My theory was, as soon as I have COS triggering Asterisk correctly, then I can look at getting the audio in working properly. TIA -- Jim Whiteside.
