Hi Thomas,
I saw your mail to Asterisk mailing list regarding ISDN BRI problem.
It was about answering the call. I'm facing a similar problem. I had
briefed the problem below. Please tell me what are the parameters to
check/change to get it working.
I have Hisax ISDN BRI card. I configured extension.conf, modem.conf
correctly and could make outward dialing. But when I make incoming call
to the ISDN MSN. It is hanging in the "Answer(..." application and
after some time hanging up the call. When I followed the Asterisk
commands to i4l modem ( /dev/ttyI0 ) it was
> ATA
> AT+VRX+VTX ( note: asterisk not getting VCON from modem )
< CONNECT
THanks in ADVance
