GUI Parameter Name
*
Valid Range and Description
H245InitTimeOut
Timeout in seconds for establishment of H.245 connection (Default 30 sec).
RTPMultiplierUsed
0 = The Coder Packetization period in Terminal Capability Set is set to basic coder
period, such as 30 msec for G.723.
1 = The Coder Packetization period in Terminal Capability Set takes into consideration
the Multiplication Factor [M]. For example if M=2, packetization period of G.729 coder is
set to 40 msec (default).
EnableReversalPolarity
(Polarity Reversal)
0 = The line polarity is not changed on answer (default)
1 = The FXS GW will change the line polarity on call answer and change it back on call
release.
The FXO GW will send H.225 CONNECT message on detection of Polarity reversal
signal.
EnableCurrentDisconnect
(Enable Current Disconnect)
0 –No current disconnect (default)
1 - FXS Gateway will generate a "Current disconnect pulse" of 900msec after a call is
released from IP.
Applicable only for MP-1xx FXO Gateways.
TimeForReorderTone
Duration of played reorder tone in seconds (default 5 sec).
Applicable for FXO port. The tone is played before releasing the FXO line.
TimeForDialTone
(Dial Tone Duration)
Duration of played dial tone (default 16 sec),
The dial tone is played at FXS Gateway port, after phone is picked up, or after the FXO
Gateway seizes the line in respond to ringing. During play of the dial tone, Gateway waits
for DTMF digits. Applicable for both FXS and FXO Gateways when “Automatic dialing”
feature is disabled, “IsDialNeeded = 0”
EnableQ931Multiplexing
(Q.931 Multiplexing)
0 = H.323 Q.931 multiplexing is disabled (default)
1 = H.323 Q.931 multiplexing is enabled
When multiplexing is enabled, the H.323 Gateway uses same socket for all H.225
messages send to same destination.
H323BasePort
(H.323 Base Port)
Starting TCP/UDP transport port for H.225/H.245 messages. H.323 Gateway will use
dynamic ports (except RTP ports) starting from H323Baseport to H.323BasePort+500.
For example if H323BasePort = 10000. H.323 Gateway will use dynamic ports within the
range 10000 to 12000. These ports are used for RAS, H.225 and H.245 protocols, not
including RTP ports.
If not specified, the default port range: 32000 to 65000
SecureCallsFromIP
(IP Security)
0 = Accept all H.323 Calls (default)
1 = Accept H.323 calls only from IP addresses defined in Prefix routing table.
When SecureCallsFromIP is enabled, Gateway will reject calls from unknown IP
addresses.
When using Gatekeeper in routed mode it is recommended to set this parameter to "0",
leaving to Gatekeeper the decision to accept or reject H.323 calls.
DestNumberType
0 = Unknown (default)
1 = International Number
2 = National Number
3 = Network Specific Number
4 = Subscriber Number (or local)
6 = Abbreviated Number
7 = Reserved for extension
The Number Type (TON) parameter is used in H.225 Setup messages.
Not all combinations of TON/NPI are allowed. Usually, you need to select one of the
following TON/NPI sets:
0/0 (Unknown/Unknown),
1/1 (International/ISDN)
2/1 (National/ISDN)
4/1 (Subscriber/ISDN)
Note: Numbering Plan/Type in the Number Manipulation table, if presented, will override
the value defined by the global parameter. Using the Number Manipulation tables
enables configuration of the Numbering Plan and Type on a per call basis, according to
destination (or source) number.

0 = Unknown (default)
1 = ISDN/Tele
