Something happened yesterday at some point.

Two month old installation has been working fine and all of a sudden, this morning there was no inbound or outbound calls.

I quickly rebooted and the incoming calls returned however we are still unable make outbound calls.

We get the message "The number you have dialed is not in service"

We have a Sangoma A500 BRI card and 4 ISDN channels

span=2,0,0,CCS,AMI
bchan=1-2,4-5
hardhdlc=3,6
loadzone=uk
defaultzone=uk
echocanceller=OSLEC,1-4

This is the the file that bothers me - shouldn't bchan be 1-2, 3-4 ?

6 channels to configure.

Setting echocan for channel 1 to OSLEC
Setting echocan for channel 2 to OSLEC
Setting echocan for channel 3 to OSLEC
Setting echocan for channel 4 to OSLEC
Setting echocan for channel 5 to none
Setting echocan for channel 6 to none

This also shows 6 channels when I only have 4.
