Call Status
Account This column displays each SIP account in the Device.
Duration This field displays how long the current call has lasted.
Status This field displays the current state of the phone call.
Idle - There are no current VoIP calls, incoming calls or outgoing calls being made.
Dial - The callee's phone is ringing.
Ring - The phone is ringing for an incoming VoIP call.
Process - There is a VoIP call in progress.
DISC - The callee's line is busy, the callee hung up or your phone was left off the hook.
Call Type This field displays the call direction type of the current VoIP call. Outgoing Call - It's a SIP VoIP
call made by local phone ports, and this SIP account is able to issue a (SIP-based) call setup
to the SIP account of remote peers for a VoIP call establishment. This (SIP-based) call setup
signal is sent to the SIP server first, and then the SIP server would relay it to the target peer after
correctly resolving and locating the target peer. During the call setup (signaling) phase,
Calling state is displayed in the Status field, and it turns to InCall state once the call is
successfully established.
Incoming Call - It's a SIP VoIP call made or originated by remote SIP accounts to connect to
this local SIP account. One or more local phone ports can be configured to receive this type
of call, see the Incoming Number below, and all of them should begin to ring during the call
setup (signaling phase), see the Status above. Once some remote SIP accounts start to ring
one local phone, answer by off-hook to the call, and the call is successfully established. The
other ringing local phone ports will stop ringing and turning to InCall state in the Status field.
Internal Call - It's a local VoIP call between two different local phone ports. No SIP signaling is
needed and thus no SIP server is involved to establish this type of call. This type of call is
established via the Internal and Non-SIP local setup signaling procedure between the call-
originating and call-terminating local phone ports. In general, one or more local phone ports
can be designed to receive this type of call, and once any of the ringing phones answer the
call, the other ringing ones will stop ringing. During the call setup phase (signaling phase),
Calling state is displayed in Status field, and turns to InCall state once the call is successfully
established.
Codec This field displays what voice codec is being used for a current VoIP call through a phone port.
From Phone Port This field displays the phone ports type used to originate, start, or create the current VoIP call.
Type Type Two possible type values will be displayed here: SIP - For the current call which is
categorized as Incoming Call in the Call Type filed, this field will show the type SIP. FXS - As for
the other cases: Outgoing Call and Internal Call, this field will show the corresponding local
phone port type: FXS, the legacy analog phone port on the device.
