[asterisk-r2] Problems: Siemens SDE - Asterisk Digium E1 TE122

[Enrique Gomez]

I'm trying to connect a Siemens SDE central plate with a TE122 Asterisk, the current configuration I have is:

cat /etc/dahdi/system.conf 
span=1,1,0,cas,hdb3
cas=1-15:1101
dchan=16
loadzone=ar
defaultzone=ar

and the utility shows me dahdi_tool OK 

TxA 111111111111111
TxB 111111111111111
TxC 000000000000000 
TxD 111111111111111 

RxA 111111111111111 
RxB 000000000000000 
RxC 000000000000000 
RxD 111111111111111 

Download the SVN version of Asterisk with support for MFCR2, and configure like this cat /etc/asterisk/chan_dahdi.conf 

[channels] 
echocancel=no 
rxgain=0.0 
txgain=0.0 
signaling=mfcr2
mfcr2_variant=ar 
mfcr2_get_ani_first=yes 
mfcr2_max_ani=10
mfcr2_category=national_subscriber 
mfcr2_logdir=span1 
mfcr2_logging=all 
; mfcr2_mfback_timeout=5000 
mfcr2_allow_collect_calls=no 
mfcr2_double_answer=no 
mfcr2_immediate_accept=no 
; mfcr2_advanced_protocol_file = / usr/etc/r2proto.conf 
mfcr2_forced_release=no 
mfcr2_charge_calls=yes 
mfcr2_max_dnis=20 
callgroup=0 
pickupgroup=0 

group=0 
context=coop
channel=>1-15 

and utility dahdi_tool running Asterisk shows me this: 

TxA 111111111111111 
TxB 000000000000000
TxC 000000000000000 
TxD 111111111111111 

RxA 111111111111111 
RxB 000000000000000 <--- And there appears 111111111 every 20 or 30 seconds
RxC 000000000000000 <--- And there appears 111111111 every 20 or 30 seconds
RxD 111111111111111 

And occasionally shows me Yellow Alarm / Recovering and the 

cat /var/log/asterisk/full
