[asterisk-users] No D-channels available! Using Primary channel 16 as D-channel anyway!
Dear Gurus,
i am facing some unknown problem here..
first, let me describe my case.
my office is using a nortel merridian option 11c PBX. and it is
connected to the provider thru a E1 card, which is working fine with no
problem.
my plan it to slot in a server with 2 TE11XP card to intercept the
outgoing calls.
Provider <--te11xp---> asterisk <---te11xp------> nortel merridian
option 11c
i had my asterisk set up with these configuration.
zaptel.conf
-------------------------------------------
loadzone=uk
defaultzone=uk
span=1,1,1,ccs,hdb3,crc4,yellow
span=2,0,1,ccs,hdb3,crc4,yellow
bchan=1-15,32-46
dchan=16,47
bchan=17-31,48-62
-------------------------------------------
where span 1 is to the provider and span 2 is to the PBX
zapata.conf
---------------------------------------------
context=from-pstn
switchtype=dms100
signalling=pri_cpe
callerid=asreceived
group=1
callgroup=1
pickupgroup=1
rxgain=0.0
txgain=0.0
channel=>1-15,17-31
context=from-pstn
switchtype=dms100
signalling=pri_cpe
callerid=asreceived
group=2
callgroup=2
pickupgroup=2
rxgain=0.0
txgain=0.0
channel=>32-46,48-62
------------------------------------
able to start asterisk. Span 2 loaded beautifully, no problem or errors,
but i get this
"WARNING[13655]: chan_zap.c:2287 pri_find_dchan: No D-channels
available! Using Primary channel 16 as D-channel anyway!"
warning message from span 1. which i have no idea what happened..
the funny part is, i am able to receive calls, no problem at all. CID
and DID are pass thru (for incoming).
but when i try to make a outgoing calls, i got errors PRI HANGUP CAUSE 1
from the provider.
i did a pri debug span 1 for the call i dialed, below are the msg.

And, since you're using E1 I believe both your switchtype should be euroisdn instead of dms100. Leo

Hi, maybe I am a little bit late with this answer.
