At least the german manual says, that the modem is also able to use
3-bit-ADPCM. (The ZyXEL-1496-Webpages even mention 'new-3-bit' and 4 bit
ADPCM). 
So I converted my welcome-message to 3-bit ADPCM and inserted AT+VSM=3
to the mgetty-initchat. That worked, the modem played the welcome-message.
But by looking at the logs, I'm getting confused:


07/30 12:41:16 yS1  playing voice file /var/spool/voice/messages/welcome
07/30 12:41:16 yS1   vgetty: raw modem data header found
07/30 12:41:16 yS1   vgetty: modem type ZyXEL 1496 found
07/30 12:41:16 yS1   vgetty: compression method 0x0003, speed 9600, bits 3
07/30 12:41:16 yS1   voice command: 'AT+VSM=3' -> 'OK'
07/30 12:41:16 yS1    vgetty: AT+VSM=3
07/30 12:41:16 yS1    ZyXEL 1496: AT+VSM=3
07/30 12:41:16 yS1    ZyXEL 1496: OK

[...]

07/30 12:41:30 yS1  recording voice file /var/spool/voice/incoming/va00246.rmd
07/30 12:41:30 yS1   voice command: 'AT+VSM=2' -> 'OK'

Is it possible to use AT+VSM=3 for recordings, too? 

OK, next question.

Earlier on the list somebody mentioned that with ATS40.2=0 and ATS48.0=1
it is possible to access the raw caller-id, that comes through the line.

Did anyone try this? Is it working for germany?

thanx
