SIP Operation Manual V2.6
Trunk Incoming Prompt Voice: Select the greeting (must use the IVR 132 function to record a voice
file) when FXO receives an inbound call.
Enable: To enable a line; if some lines are not used, disable them (Pause Function) to avoid
unnecessary waiting when an incoming call is diverting to this line.
Hotline Functions
FXS port: When the user picks up the phone, the gateway automatically dials your assigned hotline
number. When in hotline mode, other lines cannot be used.
FXO port: When receiving a call from an outside line, the gateway will divert the call to the
assigned hotline number.
Hot Line No.: Enter the hot line number for an automatic dialing function.
Warm Line: When the Warm Line function is in use, user can dial a number. Otherwise the system
will divert incoming calls from an outside line to the Hot Line Number after a set wait time.
Example:
Assume the assigned hotline for 2S2O line 3 is 701 and the Warm Line(Hot Line Delay) is 5 seconds. If
no extension number is dialed within 5 seconds, the call will be automatically diverted to the assigned
hotline (ext 701). The system allows users to record a voice prompt (e.g. “please enter an extension
number or wait for the operator to connect you”) to use in this situation.
Assume the assigned hotline for 2S2O line 4 is 702 and the wait time is 0 second. When P4 receives a call
from an outside line, it will be automatically diverted to extension 702.
Dail-out Prefix: It is the number dialed automatically by the system when the FXO interface diverts
a call to the PSTN by VoIP. (S series gateways do not have this function).
Example:
If PBX extension needs to dial “0” to make a PSTN call, and the FXO are connected to PBX extension. In
this case, the Dial-out prefix should be set to “0”. If the PBX requires some delay time before capturing
a line, then the trunk prefix should be set as “0,” so that after dialing a 0, it will pause for 1 second before
dialing the destination number. Each comma represents a 1 second delay. If more delay time is required,
simply add more commas. Please note that if a Dial-out prefix is set, the line won’t be able to dial to any
PBX extension line (FXS interface does not have a trunk prefix function). Please refer to Section 6 if
required to dial to a PBX extension line and PSTN concurrently.
Group Hunting: Select group hunting when there is an incoming call, the gateway will automatically
assign an unassigned call according to Hunting Priority. If Line 2 does not want to be set as an
assigned line to receive any inbound calls, the function can be disabled. Users can also use the Up
or Down key to adjust hunting priority (No setting is required for the FXO interface).
