Yes, I was also using it some time before, but I always run into problems
where my mobile phones stopped to work after a few calls and I have to remove
the battery to get them working again and such funny things.

I believe that there were problems with the RF-Frequencies as I had too many
bluetooth devices at one place.

I am working together with odicha on chan_datacard.
I have not tried out chan_sebi, but chan_datacard has no problems with audio
delay for me.

I have also not tried out DTMF soo far, but will do it in the near future. As
faar as I can see the datacards support DTFM stuff so this should be no
problem.

I am building chan_datacard agains asterisk 1.6.2-rc1.

I will try to build it agains earlier versions of asterisk.

But I must say, that chan_datacard is NOT ready for prodution now!
It sill has some seroius bugs with incorect terminated AT-Commands sometimes
send by the datacards and multiline SMS.

It can work for some calls but I am pretty sure that it will get "out of sync"
with the datacard after a while. So please only use it for testing purposes.

Regards, Artem
