    Hello


    I notice a major difference in what Asterisk console is telling me
    (which seems correct) and what Asterisk Manager is telling.


    A SIP user is called, and the phone does not ring. This is the
    situation.


    On Asterisk console I see (which seems to be in line with an
    unreachable phone) :

    [Feb 11 11:31:31] VERBOSE[15653][C-00000319] app_dial.c: Called
    SIP/mysipuser6
    [Feb 11 11:31:37] VERBOSE[15653][C-00000319] app_dial.c: Everyone
    is busy/congested at this time (1:0/0/1)
    [Feb 11 11:31:37] VERBOSE[15653][C-00000319] pbx.c: Executing
    [202@from-PBX:253] NoOp("SIP/mysipuser12-0000157d",
    "DIALSTATUS=CHANUNAVAIL") in new stack

    However on Asterisk Manager interface I see the event :

    11:31:31
    Array
    (
        [0] => Event: DeviceStateChange
        [1] => Privilege: call,all
        [2] => SystemName: voipserver1
        [3] => Device: SIP/mysipuser6
        [4] => State: RINGING
    )


    I can reproduce this easily every time :

    [Feb 11 11:31:46] VERBOSE[15719][C-0000031a] app_dial.c: Called
    SIP/mysipuser6
    [Feb 11 11:31:53] VERBOSE[15719][C-0000031a] app_dial.c: Everyone
    is busy/congested at this time (1:0/0/1)
    [Feb 11 11:31:53] VERBOSE[15719][C-0000031a] pbx.c: Executing
    [202@from-PBX:253] NoOp("SIP/mysipuser12-0000157f",
    "DIALSTATUS=CHANUNAVAIL") in new stack

    11:31:46
    Array
    (
        [0] => Event: DeviceStateChange
        [1] => Privilege: call,all
        [2] => SystemName: voipserver1
        [3] => Device: SIP/mysipuser6
        [4] => State: RINGING
    )


    Why is Asterisk Manager reporting a RINGING state if there is no
    SIP 180 RINGING received ?! When issuing a SIP DEBUG, I see a SIP
    INVITE but no response (so no SIP 180 or 183).


The answer seems to be, because that's the way chan_sip was written. As soon as an outgoing call is attempted it sets some internal state to ringing, which is then used when it reports device state information. DeviceStateChange is just reporting what chan_sip told it.

So if "DeviceStateChange" is not reporting the real state of a SIP user/device (like 180-ringing), which event does ?!



Kind regards.
