Use given
Gatekeeper
GatekeeperIp
Single IP address or several IP address if redundant
gatekeeper option is enabled.
H323gw IP
Redundant
Gatekeepers
IsRedundantGKUsed
Specify list of gatekeeper IP addresses using
GatekeeperIp parameter. Gateway starts working
with first GK from the list. In case of a failure with first
GK, the Gateway tries to find other GKs from the list.
Once GK is found, the Gateway continues working
with it, until the next failure. If none of the GKs
respond, Gateway goes over the list again.

Gatekeeper,use
routing table
When Gatekeeper isn’t used, it is necessary to define IP routing table, to enable MP-
1xx Gateway to find destination IP address, according to received dial number. The
routing table is defined in ini file, using PREFIX or per phone number definitions.
The Gateway first searches for Phone table to find a destination IP address, than it
looks for Prefix parameter, and later for ”Prefix = *,<IP address>" definition.
“Prefix = *, <IP address>“ defines destination IP address for any other phone number.
Fall Back to
internal routing
table
IsGKFallbackUsed
Gateway starts using internal routing table (phone to
IP, or prefix to IP) if communication with Gatekeeper
is lost. Gateway returns to Gatekeeper when
communication is restored.

Channel2Phone= <channel>,<phone>
or ChannelList = port, number, phone
EndPoints Phone
numbers
Set numbers to
end points
The easiest way to define endpoint phone number is to use ChannelList parameter. Fo
r
example, to define 101 to 107 numbers for an MP-108, use a single line: ChannelList =
0,8,101.
The first parameter (0) indicates the first endpoint number.
The second parameter (8) indicates the number of endpoints.
The third parameter (101) indicates the first endpoint phone number.
Up to ten such ChannelList definitions can appear in the same ini file.
One or more phone numbers in the ChannelList can be modified by using
Channel2Phone definition, following the ChannelList parameter in the ini file.
MaxDigits
Maximal number of digits in dialed number.
General Max digits
Dial plan
TimeBetweenDigits
Timeout between dialed digits, used to terminate
dialing. Usually it is set to 4 seconds.
