network, there are two methods that can be used. ( FXO port
dialing out only )
‹ 1-stage dialing: When there is an SIP trunk incoming call to
the VGW-400 series, it selects a free FXO port and dial-out
digits directly without doing DM and route plan directly.

mode, the incoming call from VoIP or FXO port
only routes to FXS port. However, the outgoing
call from FXS port goes to either VoIP or FXO
port depending on DM and route plan.
‹ 2-stage dialing: When there is an SIP trunk incoming call to
the VGW-400 series, it answers this call and plays dial tone
to SIP trunk to wait for SIP trunk user to dial digits and send
these digits to FXO/PSTN network one by one.
