Hello everybody!
I'm new to Asterisk and VISDN and I've got a problem with my reference
implementation here.
I'm using an ISDN-Card using the Cologne chipset acting as terminal
equipment.
Outgoing calls are fine, incoming calls are signaled correctly at my
internal sip phones but even after answering the call there is no
connection. At the sip phone you can't hear anything, at the calling
line there's no indication that the phone has been picked up.
I've attached pieces of my configuration at the end, if you need some
more please tell me...
I've tried Asterisk with all patches installed and the Asterisk as it
is. No difference. What did I do wrong?
Thanks for your help,
Philipp

This is the console log for an incoming call (I've deleted my telephone
numbers...). Dialing -> SIP ringing -> SIP picked up -> can't hear
anything -> SIP hanged up
Asterisk Ready.
