I'm looking for a DTMF generator chip, it seams that this kind of chip is no
more available.
Any help will be very appreciated.

But they have to exist, because every single phone (landline and cordless)
and any other device that has to dial would have one.
Surely you can find them if you expand your search, and then simply toss
away the unneeded functions.
If this is for building a handful or less, buy some cheap telephones
and extract the IC (and keypad) from them.
As a side note, do they use the same tones over there as they do
in North America? It's been a long time since I paid any attention
to telephones, but it may be important to check.
