[asterisk-r2] Collect Call

[Guilherme]

Hi,

I have the problem below when I use DAHDIAcceptR2Call(yes)

When the called number hook off the phone the call is finished with this error.


[May 13 11:34:24] ERROR[718]: chan_dahdi.c:1606 dahdi_r2_write_log: Chan 177 - Protocol error. Reason = Invalid R2 state, R2 State = *Unknown*, MF state = MF Engine Off, MF Group = Backward Group B, CAS = 0x08
DNIS = 2199, ANI = 1182240518, MF = 0x20
[May 13 11:34:24] ERROR[718]: chan_dahdi.c:1378 dahdi_r2_on_protocol_error: MFC/R2 protocol error on chan 177: Invalid R2 state

This case occur only in Collect Call, other calls are fine.

my chan_dahdi.conf

signalling=mfcr2
mfcr2_variant=br
mfcr2_get_ani_first=no
mfcr2_max_ani=20
mfcr2_max_dnis=4
mfcr2_category=national_subscriber
;mfcr2_logdir=span1
mfcr2_call_files=no
;mfcr2_logging=all
mfcr2_mfback_timeout=-1
mfcr2_metering_pulse_timeout=-1
mfcr2_allow_collect_calls=no
mfcr2_double_answer=yes
mfcr2_immediate_accept=no
mfcr2_forced_release=no
mfcr2_charge_calls=yes
language=pt_BR

If I set only mfcr2_allow_collect_calls=no, none call is blocked, I need to set mfcr2_double_answer=yes to block then.

  You can use DAHDIAcceptR2Call() application to accept the call if that's what you want ( be sure you don't Answer() before, because that implicitly accepts the call ). If you don't call DAHDIAcceptR2Call and just Hangup() the call will be rejected with the specified reason in MFCR2_CAUSE variable ( if not specified, line out of order will be used).

  I have not documented the MFCR2_CAUSE variable, so you may want to ignore it, or check the code inside chan_dahdi.c to find out the valid values.

    Hi,

    I have a openr2 installed on my asterisk and I need to use mfcr2_allow_collect_calls for some calls, not for all. I want know if exist some variable that I use in my extensions.conf to block or allow a collect call for some calls.

    Tanks,
