Account This column displays each SIP account in the VMG.
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
