Hello All

We are attempting to get 300baud FSK data over a GSM link.

Ive seen different postings on this in the past and the concensus
is that it may be possible given that its FSK and at a slow rate.
Although the GSM codecs distort the phase of audio tones they should
not effect the frequencies.

Essentially the requirement comes from the fact that the equipment
at the far end can only communicate at 300baud FSK over the PSTN network.
Our end will work with GSM and needs to communicate at the 300 baud FSK.

Has anybody had any experience with this?

Many thanks for any help in advance.

Regards

Denis
