According to your manual, you seem to have set it up OK for CSD.

The number you are calling does ring? Is it a land phone line with an old modem?

Does this modem answer the call?

Does this modem have the same speed or is it auto speed set?

Do you have a land modem to make a test?

If yes, call it and see if it rings.

Then with the help of a terminal program send ATA to the modem and see if you manage to get a connection from the GSM call.

Report results.

[Ioannis]

Yes that is what i meant. The good old fashioned 28.8 or 33.6 or 56K modem. Maybe you have a laptop with such a device still on.
