Hi guys!
In our solution, we need a dial up modem with following features:
1) V.22 bis/V.34 2) AT Command interface 3) Voice Codec Support 4) SMS Support
So far, I found Si24xx from Silicon Lab:

Any other suggestion! Regards,
ETSI may have written some standards, but have they actually been adopted by any real networks?
Have you confirmed that your particular target network(s) are using any or all of those standards?
Dear Andy,
There are two protocols adopted for SMS in PSTN, protocol 1, and protocol 2!
In my case, protocol 1 is implemented.
Regards,
