[asterisk-users] device state of SIP device is stucked into NOT_INUSE, and cannto be reverted to unavailable

[Yaroslav Panych]

Hello

Have a setup of asterisk with realtime SIP devices.
Trying to organise monitoring of my SIP devices. Once device
registered, its state becomes NOT_INUSE (result of
DEVICE_STATE(SIP/device) function).
Simulating of device breakage - powerdown it.
Waiting for a while (minute or two), retrieving
DEVICE_STATE(SIP/device) again - no changes! Awaited UNAVAILABLE.

doing from CLI:
sip qualify peer device load
no result.

What I did not configured?

My sip.conf
