Call Time Limit – set the call time limit after which the call is automatically terminated. The device beeps 10 s before the call ends to signal that the call end is approaching. Enter any DTMF character into the call (# on your IP phone, e.g.) to extend the call time. If the call time limit is set to 0 and SRTP is not used, the call is not time limited.

Call Receiving Mode (SIP 1/2, SIP 2) – set the way of receiving incoming calls. You can set the call receiving mode for each SIP account separately. The following three options are available:

Local Call Receiving Mode – set the way of receiving incoming local calls.

Voicemail Mode – a pre-defined voice message (as set in User Sounds) is played into the call after a timeout defined in the Pick Up in parameter in the automatic/manual call answering mode if the Only Out of Office Message is set. A beep is also played in the Voicemail mode and an up to 20-second long call recording starts (audio and video if available) for the calling user to leave a message. If no user message is recorded, a default voice message in one of the seven available languages (as set in the Voice Message Language parameter inUser Sounds) can be used.

Pick up in – this parameter is only active when the Automatic pickup mode is enabled. The call is picked up automatically after the preset timeout.

Reject Calls in DND Mode – if this function is activated, the device reject calls in the Do not Disturb mode. The function can be used for immediate call redirection at absence to a mobile phone call, for example.

DND Mode for Doorbell Button – if this function is activated, the device shall not ring when the doorbell button is pressed.

Do Not Disturb Mode with Time Profile – choose one or more time profiles to be applied to the DND mode. Set the time profiles in Directory > Time profiles.

Click the icon to set the selection from predefined profiles or manual setting of a time profile for the given element.

Connecting Time Limit – set the maximum outgoing call connection timeout after which the calls are automatically terminated. If the calls are routed to the GSM network via GSM gateways, you are advised to set a value higher than 20 s.

Ring time limit – set the maximum call setup and ringing time in which all outgoing calls are automatically terminated. If the calls are routed to the GSM network via GSM gateways, you are advised to set a value longer than 20 s. Minimum value: 1 s, maximum value: 600 s. Set 0 to disable the time parameter.

Save Image during Call – if enabled, one or more snapshots are automatically taken from each video call and saved into the call log (depending on the device type and setting). More images can be taken manually during a call on some devices.

Automatic Image Count – set the count of snapshots that shall be automatically taken during a call and saved into the call log.

Starting RTP Port – set the initial local RTP port in the range of 64 ports used for audio and video transmission. The default value is 4900 (i.e. the range is 4900–4963). The parameter is only set for SIP 1 but applies to both the SIP accounts.

RTP Timeout – set the audio stream RTP packet receiving timeout during a call. If this limit is exceeded (RTP packets are not delivered), the call will be terminated by the device. Enter 0 to disable this parameter. The parameter is only set for account 1 but applies to both the SIP accounts.

Extended SIP Logging – allow SIP telephony details to be recorded in syslog (for troubleshooting purposes only).).
