Hi David,
I've been working with an * setup with a VoiceTronix 4-port FXO card and
I had similar problems with detecting dialtone. I had to chan_vpb.c to
use a VPB driver call progress dial command, and to change the dialtone
dectection (I'm in North America) -- please see patch against version
0.7.1 below. I have not submitted this patch upstream because it's a
workaround that works for my application but leaves lots of problems
unfixed, and possibly creates other problems, so use at your own risk!
I have not yet worked with more than one line with this card so I cannot
say whether I have the other problem you mentioned.
In general, my experience using this card with Asterisk has been
negative. I hope that Digium will be releasing a multi-port FXO card
soon.
