¾ Dial Plan Priority: The parameters configured here determine which network or SIP account
to use when making outgoing calls. In the 1st field, there are options of networks. Please note
if no SIP account is set on SIP Account page, only PSTN network will be available. Otherwise
networks available are VOIP, PSTN Preferred and PSTN. If the network selected is not PSTN,
you need to choose a SIP account from the 2nd field. The following are different options:
• VOIP & Auto – The Router will always use VoIP network to make calls. As to the account,
the one specified in the matched dial plan will be chosen first. Otherwise, the account
with top priority will be selected. To view the priority, please go to the screen as shown in
Figure 4-36. If “Fallback to PSTN” box is checked, the Router will try PSTN network to
make calls after VoIP call fails.
• VOIP & Account X (a certain account) – The Modem Router will always use VoIP network
and Account X to make calls. If “Fallback to PSTN” box is checked, the Router will try
PSTN network to make calls after VoIP call fails.
• PSTN Preferred & Auto – The Router will select the PSTN network and VoIP account to
make calls according to your dial plans set on Dial Plan page. If no dial plan is matched
with your outgoing call, then PSTN network will be automatically selected.
