Hello- After configuring DAHDI and starting asterisk, I get the following message continuously on the Asterisk console: WARNING[2057]: chan_dahdi.c:4158 pri_find_dchan: No D-channels available! Using Primary channel 16 as D-channel anyway! My card is a D410P configured for E1, only the first span is configured, and configuration snippets are as follows: From /etc/dahdi/system.conf: (auto configured, first span only shown:) # Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" span=1,1,0,ccs,hdb3,crc4 # termtype: te bchan=1-15,17-31 dchan=16 echocanceller=mg2,1-15,17-31 ---------------------------------------------------------------------- From /etc/asterisk/dahdi-channels.conf (included in chan_dahdi.conf): ; Span 1: TE4/0/1 "T4XXP (PCI) Card 0 Span 1" group=0,11 context=from-pstn switchtype = euroisdn signalling = pri_cpe channel => 1-15,17-31 context = default group = 63 ---------------------------------------------------------------------- QUESTION: Shouldn't asterisk pick up from dahdi.conf that the signalling channel is 16? Why the error message? Thanks Scott

Probably a misconfiguration or you havent plugged the cable in yet.

If you have a 4 port analogue card for example then if that card is detected first you will find it is channels 1-4 and therefore your ISDN30 will be channels 5-19,21-35 and the D channel being 20.
