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

[Josué Conti]

I returned on the old configuration, just disabling r2proto.conf and the
error occours, for some calls, but not for all calls, libe below:

[2015-02-23 17:23:10] ERROR[11893]: chan_dahdi.c:2004 dahdi_r2_write_log:
Chan 95 - Protocol error. Reason = Invalid Multi Frequency Tone, R2 State =
Seize ACK Transmitted, MF state = DNIS Request Transmitted, MF Group =
Backward Group A, CAS = 0x00
DNIS = 003001000341, ANI = , MF = 0x46
[2015-02-23 17:23:10] ERROR[11893]: chan_dahdi.c:1789
dahdi_r2_on_protocol_error: MFC/R2 protocol error on chan 95: Invalid Multi

[2015-02-23 17:23:10] NOTICE[11893]: chan_dahdi.c:2035
dahdi_r2_on_line_idle: Far end unblocked on chan 95

So, my current configurations are:

system.conf
#Sangoma A104 port 4 [slot:4 bus:9 span:4] <wanpipe4> Hipath 4000
span=4,4,0,cas,hdb3
echocanceller=mg2,94-108,110-124
#echocanceller=none
# termtype: te
cas=94-108:1101
cas=110-124:1101
