Ok, this helps a bit. I checked the zaptel source code, and the "No data available" error is related to "tone zones" which I think is the definition of how to play the different DTMF tones (digits). Apparently this differs between countries. Extract from kernel/zaptel-base.c: /* The tonezones are loaded by ztcfg based on /etc/zaptel.conf. */ printk(KERN_WARNING "zaptel: Cannot start tones until tone zone is loaded.\n"); /* Note that no tone zone exists at the moment */ res = -ENODATA; So it seems you need to configure the correct tonezones in /etc/zaptel.conf and then run ztcfg. It is not something I am familiar with, but you can probably find information on this with Google or on other mailing lists, it does not appear to be specific to chan_ss7. But do let us know if you solve it or not in case it is a bug in the way chan_ss7 uses the zaptel driver. Maybe chan_ss7 should load the tonezones itself if they are missing? > I have alway the error message : Short read on linkset "green" CIC=54 (read > only 0 of 160) errno=11 (Resource temporarily unavailable) (supressed 0). Again, from reading the source it is not clear that this is necessarily a real problem. So if you solve the tonezone problem and the audio is otherwise ok on the lines, I think you can ignore the message, it should only appear once every 10 seconds anyway. Hope this helps, - Kristian.
