Hi,
We are trying to connect an Asterisk server with a Channel Bank with E&M
interfaces using a RedFone TDMoE device.
The CB have a E1 CAS interface.
OS: Ubuntu Server 11.10 64 bits
dahdi: dahdi-linux-complete-2.6.1+2.6.1
Redfone configuration:
/etc/redfone.conf
[span1]
framing=cas
encoding=hdb3
System configuration:
/etc/dahdi/system.conf
dynamic=ethmf,eth0/00:50:c2:65:e0:64/0,31,1
dynamic=ethmf,eth0/00:50:c2:65:e0:64/1,31,0
e&me1=1-15,17-31
dchan=16
alaw=1-31
loadzone = fr
defaultzone = fr
Error message:
========================================================
# dahdi_cfg -vvvvv
Changing signalling on channel 1 from Unused to E & M E1
Changing law on channel 1 from Mu-law to A-law
DAHDI_CHANCONFIG failed on channel 1: Invalid argument (22)
Selected signaling not supported
Possible causes:
e&me1 signaling is being used on a T1 line (use e&m)
RBS signaling is being used on a E1 CCS span
Signaling is being assigned to channel 16 of an E1 CAS span
=========================================================
I don't understand the last possible cause mentioned: "Signaling is being
assigned to channel 16 of an E1 CAS span", because the dchan is channel 16.
Where is the error?
Thank you.
