[asterisk-r2] OpenR2 and A104DE (Sangoma Technologies)

[Josué Conti]

Hy guys, how are you?
I´m trying make calls from Siemens HiPath to Asterisk-1.6.2.24, DAHDI
Version: 2.9.1.1 Echo Canceller: HWEC, using openR2 version 1.3.3 (release)
and report these erros below:

For sample, trying call to Sangoma Technologies:
[2015-02-19 11:23:27] ERROR[10903]: chan_dahdi.c:2004 dahdi_r2_write_log:

= Seize ACK Transmitted, MF state = DNIS Request Transmitted, MF Group =
Backward Group A, CAS = 0x00

dahdi_r2_on_line_idle: Far end unblocked on chan 105


My chan_dahdi.conf is:
;Sangoma A104 port 4 [slot:4 bus:9 span:4] <wanpipe4> MFCR2 S/CRC4 HIPATH

mfcr2_call_files=yes
mfcr2_logging=all

mfcr2_double_answer=no
mfcr2_metering_pulse_timeout=4000
; Needed because this PABX delay digits forward
mfcr2_mfback_timeout=5000
mfcr2_charge_calls=yes
; This PABX tends to bug without this
mfcr2_forced_release=yes
;mfcr2_metering_pulse_timeout=-1
;mfcr2_advanced_protocol_file=/usr/etc/r2proto.conf
context=default
group=2
channel => 94-108:1101
channel => 110-124:1101


Do you have any idea why reason this happening?

With Best Regards
