¾ Preferred Receive Ptime: Ptime, short for packet time, refers to the time interval for a voice
packet to be sent by the remote caller. The unit is ms (millisecond). Usually the default value
20ms is OK.
¾ Priority: Select a priority for this account. This priority is useful when more than one account
is added in this Modem Router.
¾ Incoming Call Route: Select which line the incoming VoIP call will be routed to.
• None: All incoming VoIP calls will be denied.
• Phone 1/Phone 2: The incoming call will be routed to either Phone1 or Phone 2
randomly.
• Idle: The incoming call will be routed to idle phone in priority.
• All: The incoming call will be routed to both Phone1 and Phone 2 synchronously.
• PSTN 2nd Stage Dial: The incoming call requires second stage dial. This function is
applicable on the FXO ports that function as a bridge between VoIP call and PSTN. The
user can remotely use the PSTN line to initial a call.
¾ MWI: MWI is short for Message Waiting Indicator. Enable this option, so there will be
indications when voice message are received.
¾ Preferred Codec (1~4): Codec is known as Coder-Decoder which is used for data signal
conversion. Each codec uses a different bandwidth and hence provides different levels of
voice quality. The default codec settings are shown in the corresponding field for your
reference. Preferred Codec1 owns the top priority. You can change the value if you are
provided with this parameter; otherwise leave it default.
4.7.2 Dial Plan
Choose “Voice”Æ“Dial Plan”, you can see the next submenus:
This section includes Dial Plan List, Forbidden Call and Emergency call. The function allows users
to set rules for outgoing calls.
4.7.2.1 Dial Plan List
Choose “Voice”Æ“Dial Plan” Æ“Dial Plan List”, you will see the screen similar to Figure 4-37.
Dial Plan List function allows users to define rules to control outgoing calls. Each rule requires
prefix number, destination, Max length and operation (Strip Prefix/Replace Prefix/Add Number).
Prefix number is the key to decide which rule takes effect. If actual numbers dialed match prefix
number defined in the dial plan, the dialed number will be operated and routed to the specified
network according to this plan. Besides, operation of stripping prefix, replacing prefix or adding
prefix, is helpful for users to make a quick and easy call.
