Hi Gordon,

Gave those settings a try and still no joy :( I have managed to get rid of the Red Alarm by changing the cable! But I still get :-

== Starting post polarity CID detection on channel 1
    -- Starting simple switch on 'DAHDI/1-1'
[May  1 08:59:04] WARNING[11653]: chan_dahdi.c:7311 ss_thread: CID timed out waiting for ring. Exiting simple switch
    -- Hungup 'DAHDI/1-1'

This is so annoying :(

Best Regards,
