[asterisk-users] dahdi with isdn nt_mode, phone no signal still.
Hi people! I have managed to set up asterisk 1.8.5. with my 2 ISDN HFC boards on asterisk. On which DAHDI tells me also properly that both of my boards are registered, one in TE and the other on in NT mode. Calls do successfully come inside, but I want to connect my ISDN phone at the board, but the phone is death. What did I make wrong?! dahdi_scan: office tamer # dahdi_scan [1] active=yes alarms=OK description=HFC-S PCI A ISDN card 0 [TE] name=ZTHFC1 manufacturer=Cologne Chips devicetype=HFC-S PCI-A ISDN location=PCI Bus 01 Slot 01 basechan=1 totchans=3 irq=17 type=digital-TE syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=AMI framing_opts=CCS coding=AMI framing=CCS [2] active=yes alarms=OK description=HFC-S PCI A ISDN card 1 [NT] name=ZTHFC2 manufacturer=Cologne Chips devicetype=HFC-S PCI-A ISDN location=PCI Bus 01 Slot 02 basechan=4 totchans=3 irq=21 type=digital-NT syncsrc=0 lbo=0 db (CSU)/0-133 feet (DSX-1) coding_opts=AMI framing_opts=CCS codingframing=CAS office tamer # and dahd status in asterisk: office*CLI> dahdi show status Description Alarms IRQ bpviol CRC4 Fra Codi Options LBO HFC-S PCI A ISDN card 0 [TE] OK 0 0 0 CCS AMI 0 db (CSU)/0-133 feet (DSX-1) HFC-S PCI A ISDN card 1 [NT] OK 0 0 0 CAS Unk 0 db (CSU)/0-133 feet (DSX-1) TE-mode works fine so far.

What did I make wrong?!Afaik ISDN phones need power to work. You would need a HFC-S card with a power plug where you can hook up power from the computer's power supply so the card can power the phone. Like Sangoma's B700. Alternatively perhaps you could try to power the phone through an NT1? Would you mind sharing which version of DAHDI you used and where you got the HFC-S patch? Regards, Patrick
