Connectiong asterisk box with PRI

I have two machines each having a sangoma card.
One has a sangoma 4 port E1 card and the other one has single port E1 card.
I made a cross cable with 1 crossing 4 and 2 crossing with 5.
I configured both cards.
When i connected PRI with the cards the lights turned yellow.
Here is the output of " zap show status"
For Quad-port E1:-
Description Alarms IRQ bpviol CRC4
wanpipe1 card 0 OK 0 0 0
wanpipe2 card 1 RED 0 0 0
wanpipe3 card 2 RED 0 0 0
wanpipe4 card 3 RED 0 0 0
For single port E1:-
Description Alarms IRQ bpviol CRC4
wanpipe1 card 0 OK 0 0 0
Output of ztcfg -vv shows no errors.

The problem is in extension.conf of single port E1 i have:
exten => 234,1,Dial(Zap/g1/666)
It gives following error:
localhost*CLI> dial 234@default
– Executing Dial(“OSS/dsp”, “Zap/1/”) in new stack
Jun 6 09:09:53 NOTICE[30163]: app_dial.c:1012 dial_exec_full: Unable to create channel of type ‘Zap’ (cause 0 - Unknown)
== Everyone is busy/congested at this time (1:0/0/1)
== Auto fallthrough, channel ‘OSS/dsp’ status is ‘CHANUNAVAIL’
== Console is full duplex
<< Hangup on console >>
Please help me out…:frowning:
Thanks in advance.

change your zapata.conf like this

context = default
switchtype = euroisdn
signalling = pri_net
group = 1
channel => 1-15
channel => 17-31

hope this will solve your problem

Yups it did solve my problem …thnx for the timely reply.
