Can you provide a verbose log level 5 with 'capi debug' ? I would like to compare the capi messages. Maybe the switch just send an alerting message. > If I add the 'o' to the existing 'b' flag then dial it appears to change the > behaviour so that the phone goes 100-180 for all calls but some give > me a single (phone generated US style ring) while others give the 'double > ringing'.

When using 'o', chan_capi is doing early-b3 from the beginning before sending any digits and you will get b3-data in each case. Please send me a debug log of a connection with double ring-tone (no 183) as well.
