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

use

see

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.

Subject: [App_rpt-users] Debugging COS

 

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
