phones will ring.
Remote IP Address: the remote system’s IP address. This address is
needed for the AcerTouch feature (see below). It has to be a permanent
public IP address assigned to the remote AcerRouter 700.
Use AcerTouch: enable/disable AcerTouch by selecting Yes/No.
By definition, for a call to work over the Internet between two AcerRouter
routers, both AcerRouter have to connect to the Internet. However, since
the remote AcerRouter may not be connected to the Internet when you
call, if AcerTouch is enabled, your AcerRouter will make a non-billable
call to the remote AcerRouter to “wake” it up - to ask the remote
AcerRouter to also connect to the Internet.
FallBack: enable/disable FallBack by selecting Yes/No.
With FallBack activated, if a voice-over-IP call cannot be connected for
whatever reasons (e.g., a voice over Internet call is already in progress
between the remote AcerRouter with another one), your AcerRouter will
“fallback” and attempt to complete the call through the regular PSTN
network (rather than through the Internet).
Note: In most cases the phone number configured for the AcerTouch (a data
call) is the same as the FallBack number (a voice call). However, in certain areas
they may not be the same. If in doubt, ask your phone company. For example:
when a caller in the U.K. needs to make a PSTN call to another country, an extra
zero has to be added to the “remote phone number” for AcerTouch.
