Hi Anton,
This week I change my astunicall 1.6.0.1 to asterisk 1.6.2 with open R2, but
I had many problems. My users reported me cut calls and I matched with this
error:
[Jan 12 11:59:44] DEBUG[27798] chan_dahdi.c: Chan 12 - Bits changed from

[Jan 12 11:59:44] VERBOSE[27798] chan_dahdi.c: New MFC/R2 call detected on

The failures occurs primarily at the intermittent channels:

Far end blocked on chan 6
[Jan 12 09:00:56] NOTICE[4580]: chan_dahdi.c:1956 dahdi_r2_on_line_idle: Far
end unblocked on chan 6
I changed the balun but the problem persisted and I had to return to the
astunicall version. I have this messages
[Jan 13 23:09:58] NOTICE[30485] chan_unicall.c: Unicall/6 event Far end
blocked
[Jan 13 23:09:58] VERBOSE[30485] logger.c: -- Unicall/6 far blocked
[Jan 13 23:09:58] NOTICE[30485] chan_unicall.c: Unicall/6 event Far end
unblocked
[Jan 13 23:09:58] VERBOSE[30485] logger.c: -- Unicall/6 far unblocked
I think it could be problem of Telmex.

Jaime Guzmán

Hi Jaime.... So far this seems like a problem with asterisk 1.2 and openr2
because Ive tested it with Sangoma and Digium cards and I get the same
results.
Next Monday I?ll be testing the same Sangoma card and openr2 1.2.0 but using
asterisk 1.6.2 which now has openr2 built-in. Ill let you know if this fixes
things.
But right now what Im seen is that for some reason, PBX?es that were working
fine with asterisk 1.2 and openr2 are now giving out errors like the inalid
cas ones and red alarms with sudden blocked and unblocked channels or seize
timeout errors. It would look as if the openr2 spec for Mexico had suddenly
changed but I wont be sure until I can test it with our own E1 which is from
Axtel and gets installed on Friday.
Will keep you posted.
If you want a fast fix, when you get this, stop asterisk for a moment,
unload all sangoma or digium drivers, reload them and then reload asterisk,
this stops the invalid cas and seize timeout problems for a bit at least.

Hi everybody,
I have the same problem. The asterisk Cli frequently gives this message:
[Jan 12 09:00:44] NOTICE[4580]: chan_dahdi.c:1956 dahdi_r2_on_line_idle: Far
end unblocked on chan 6
[Jan 12 09:00:45] NOTICE[4580]: chan_dahdi.c:1947 dahdi_r2_on_line_blocked:
Far end blocked on chan 6
[Jan 12 09:00:45] NOTICE[4580]: chan_dahdi.c:1956 dahdi_r2_on_line_idle: Far
end unblocked on chan 6
[Jan 12 09:00:50] NOTICE[4582]: chan_dahdi.c:1947 dahdi_r2_on_line_blocked:
Far end blocked on chan 26
[Jan 12 09:00:50] NOTICE[4582]: chan_dahdi.c:1956 dahdi_r2_on_line_idle: Far
end unblocked on chan 26
[Jan 12 09:00:51] NOTICE[4580]: chan_dahdi.c:1947 dahdi_r2_on_line_blocked:
Far end blocked on chan 6
[Jan 12 09:00:51] NOTICE[4580]: chan_dahdi.c:1956 dahdi_r2_on_line_idle: Far
end unblocked on chan 6
[Jan 12 09:00:56] NOTICE[4580]: chan_dahdi.c:1947 dahdi_r2_on_line_blocked:
Far end blocked on chan 6
[Jan 12 09:00:56] NOTICE[4580]: chan_dahdi.c:1956 dahdi_r2_on_line_idle: Far
end unblocked on chan 6
And sometimes income a call and a few minutes later a can see:
SIP/1131-00000072 answered DAHDI/12-1
MFC/R2 call end on channel 35
[Jan 12 08:56:23] ERROR[5167]: chan_dahdi.c:1925 dahdi_r2_write_log: Chan 12
- Protocol error. Reason = Invalid CAS, R2 State = Answer Transmitted, MF
state = MF Engine Off, MF Group = Backward Group B, CAS =0x04
DNIS = 3200, ANI = 5556726862, MF = 0x20
[Jan 12 08:56:23] ERROR[5167]: chan_dahdi.c:1710 dahdi_r2_on_protocol_error:
MFC/R2 protocol error on chan 12: Invalid CAS
And the call suddenly broke. Did you resolve the problem Anton?
