Blocked MSN Numbers for the
router Enter the specified MSN number into the fields to
prevent the router from dialing the specific MSN
number.
MSN Numbers for the Router MSN Numbers mean that the router is able to accept
only number-matched incoming calls. In addition, MSN
services should be supported by local ISDN network
provider. The router provides three fields for MSN
numbers. Note that MSN services must be acquired from
your local telecommunication operators. By default,
MSN function is disabled. If you leave the fields blank,
all incoming calls will be accepted without number
matching.
Mapping to VoIP Ports Check to specify ringing from FXS1 and/or FXS2 when
the router accepts the incoming calls by identifying MSN
number(s). If you do not specify any port in this field, the
ISDN loop through ring port will be determined by the
configuration in ISDN port in VoIP>>Phone Settings.
