SIP Device Parameters

This section provides easy setup for your VoIP service. Phone port 1 and 2 can be registered to different SIP Service Provider.

SIP Device Parameters

SIP: To use VoIP SIP as VoIP call signaling protocol. Default is set to Disable.

Silence Suppression (VAD): Voice Activation Detection (VAD) prevents transmitting the nature silence to consume the bandwidth. It is also known as Silence Suppression which is a software application that ensures the bandwidth is reserved only when voice activity is activated. Default is set to Enable.

Echo Cancellation: G.168 echo canceller is an ITU-T standard. It is used for isolating the echo while you are on the phone. This helps you not to hear much of your own voice reflecting on the phone while you talk. Default is set to Enable.

RTP Port: Provide the based value from the media (RTP) ports that are assigned for various endpoints and the different call sessions that may exist within an end-point. (Range from 5100 to

65535, default value is 5100)

Region: This selection is a drop-down box, which allows user to select the country for which the

VoIP device must work. When a country is selected, the country parameters are automatically loaded.

Voice QoS, DSCP Marking: Differentiated Services Code Point (DSCP), it is the first 6 bits in the ToS byte. DSCP Marking allows users to assign specific application traffic to be executed in priority by the next Router based on the DSCP value. See Table 4. The DSCP Mapping Table:

Note: To be sure the router(s) in the backbones network have the capability in executing and checking the DSCP through-out the QoS network.

Advanced – Parameters

VoIP through IP Interface: IP Interface decides where to send/receive the voip traffic; it includes: ipwan and iplan. Easy way to select the interface is to check the location of the SIP server. If it locates some where in the Internet then select ipwan. If the VoIP SIP server is on the local

Network then select iplan.

Voice Frame Size: Frame size is available from 10ms to 60ms. Frame size meaning how many milliseconds the Voice packets will be queued and sent out. It is ideal to have the same frame size in both of Caller and Receiver.

Dial Plan Priority: Define the priority between VoIP and PSTN dial plan.

PSTN Auto-fallback: Whenever VoIP SIP responses error and error code matching with the codes in the Edit section, the VoiP calls will automatically fallback to PSTN. In the other word, the call will be called via the PSTN when VoIP SIP returns an error code.

Click the Edit to add or remove the responses code. To be sure the code is separated by a comma (,).

org/wiki/view/sip+response+codes where you can get to know the meaning of each error code.

T.38 Fax Relay: It allows the transfer of facsimile documents in real-time between two standard

Group 3 facsimile terminals over the Internet or other networks using IP protocols. It will only function when both sites are support this feature and enabled.

Advanced – PSTN Environment Adjustment

PSTN Environment Adjustment options will help you to adjust the onhook and offhook voltage detection values for your environment. You should use these if the default values are incorrect and result in PSTN calls not being detected properly, e.g. calls being terminated within 5 seconds of being answered. The actual levels are determined by your environment including the number and type of telephones used.

Note: ONHOOK means hung up.

84

To take your phone OFFHOOK, lift the receiver then press Hook/Flash until you hear your normal

PSTN dialtone, not your VoIP dialtone. Wait several seconds and then press Check Level.

You should check the OFFHOOK value for each telephone you have connected to this device.

Set the OFFHOOK voltage to the lowest setting registered for all your telephones, e.g. if your telephones return values of 4, 5 and 7 then you should set your OFFHOOK voltage to 4.

Note: The detected values will not automatically be set by the Check Level function; you must enter the lowest level detected after testing all your telephones.
