2) When an incoming PSTN call reaches the PSTN phone number of the landline connected to the FXO port
of the V431, the FXO port will pick up the landline after a very short delay. A voice prompt will be played
and ask the calling party to input a VoIP phone number or an extension phone number of the V431. Once
the V431 receives the VoIP phone number sent from the PSTN call, it will try to connect to the destination
(the VoIP phone number or the extension).
Call Model 2:
1. Calling party (from PSTN network) calls PSTN number of the FXO port connected to landline (called
party)
2. The FXO loops the landline (off hook action) and a voice prompt from the V431 prompts calling party
to enter number
3. The calling party inputs a VoIP phone number or extension phone number
4. The FXO port will use its VoIP phone number to establish the call through the VoIP network.
enable hotline and hotline Dial Wait on the FXO port
When the "Hotline" and "Hotline Dial Wait" functions are used in the FXO port, the V431 will divert an
incoming call (from PSTN network) to an extension line after a set wait time. For example, assuming the
assigned hotline for the FXO port is extension 601 and the wait time is 6 seconds. If no VoIP number or
extension number is dialed within 6 seconds, the call will be automatically diverted to this assigned hotline
(ext. 601). This feature might be very useful when the V431 is used with a PBX because the diverted call will
ring on the FXS port which could be the receptionist. The PBX will answer this call and transfer the call to a
person that the calling party would like to speak to. Fig 4-2 shows an example of hotline configuration.
