Ken, That's another step forward, thanks. But it seems to be showing that asterisk is not getting an RPT_RXKEYED signal as I feared. Nothing happens when I change the signal on pin 48 - but if I trigger a transmit e.g. via 'rpt fun 28233 *80' I get the following: Node Variable dump for node 28233: RPT_TXKEYED=1 RPT_ETXKEYED=0 RPT_NUMLINKS=0 RPT_LINKS=0 RPT_NUMALINKS=0 RPT_ALINKS=0 RPT_AUTOPATCHUP=0 RPT_RXKEYED=0 -- 8 variables Jim M0HPJ On 12 February 2012 11:57, Ken <ke2n@cs.com> wrote:

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'm still chipping away at modifying a Startech CM108 USB fob - so far I have successfully got PTT and audio out working, but I'm struggling with audio in and COS.
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
