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?

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,
