Trigger an event when callee returns 180 ringing?

The situation as follows : User A Dials User B User B returns 180 Ringing

Both of them in the same PBX (Asterisk 11.5) and registered.

I would like to know if it is possible to trigger an action when User B returns 180 Ringing (and before the we gets 200 OK)

What I'v tried to do is send the call to a label before the call connects with option "B" of Dial() command and get the SIP status with:

${HASH(SIP_CAUSE,${CDR(dstchannel)})

and

${DEVICE_STATE(SIP/${CALLEE})}

Update:

The problem is the macro launched by Dial()'s "B" option is launched before the invite is sent, so the actions I'v preformed are useless.

I'm aware it's possible to get a state of ringing with AMI (with Newstate event) but in this point I don't to add another complexity for the task.

No, it is not posible. Becuase pbx structures of outgoing channels will be no initialized.

You have go with external AMI script or have do complex rewrite of asterisk core.
