This is really interesting. Yes. As you can see from the log files, we start
sending the first digit (2), then they ask us for the next digit (tone 1
means, send me the next digit), then we send the second digit (2 as well)
and immediately they reply with tone 0, which openr2 does not recognizes. I
need to check the telmex R2 specification and see if they mention the tone
0, if they don't mention the tone 0 then I will see if I can contact someone
at telmex who can clarify what's that (I had the e-mail of someone who may
be able to help), if not, then I will just made up a meaning for tone 0 in
Group A :-), meaning "unallocated number" or something like that.
