5.4.9.3.1 Standard H323
The following settings are applicable to trunks with their Supplementary Services set to H450, QSIG or None.
Usability
· Mergeable: These settings are not mergeable. Changes to these settings will require a reboot of the system.
Configuration Settings
· Gateway IP Address: Default = Blank
Enter the IP address of the gateway device at the remote end. This address must not be shared by any other IP line
(H.323, SIP, SES or IP DECT).
· Codec Selection: Default = System Default
This field defines the codec or codecs offered during call setup.
· The available codecs in default preference order are: G.711 A-Law, G.711 U-Law, G.729 and G.723.1.
Note that the default order for G.711 codecs will vary to match the system's default companding setting.
G.723.1 is not supported on Linux based systems. The G.722 64K codec is also supported on systems with
IP500 VCM, IP500 VCM V2 or IP500 Combo cards but it not used by default.
The codecs available to be used are set through the System Codec list (System | System Codec ). The
drop-down selector options are:
· System Default
This is the default setting. When selected, the codec list below show matches the codecs set in the system
wide Default Selection list (System | Codecs ).
· Custom
This option allows specific configuration of the codec preferences to be different from the system Default
Selection list. When Custom is selected, the list can be used to select which codecs are in the Unused list
and in the Selected list and to change the order of the selected codecs.
· Supplementary Services: Default = IP Office SCN
Selects the supplementary service signaling method for use across the H.323 trunk. The remote end of the trunk must
support the same option. Options are:
· None
No supplementary services are supported.
· H450
Use for H.323 lines connected to another PBX or device that uses H450.
· QSIG
Use for H.323 lines connected to another PBX or device that uses QSIG.
· IP Office SCN
Not supported by B5800 Branch Gateway.
· IP Office SCN - Fallback
Not supported by B5800 Branch Gateway.
· Note that both ends of the SCN trunk connection must be set to fallback.
· On the system requesting backup, the required SCN Backup Options are selected, indicating that it is
requesting backup. A single system can only request backup from one other system.
· A system providing backup can provide backup for up to 7 other systems.
· Call Initiation Timeout: Default = 4 seconds. Range = 1 to 99 seconds.
This option sets how long the system should wait for a response to its attempt to initiate a call before following the
alternate routes set in an ARS form.
· VoIP Silence Suppression: Default = Off
When selected, this option will detect periods of silence on any call over the line and will not send any data during
those silent periods. This feature is not used on IP lines using G.711 between systems. On trunk's between networked
systems, the same setting should be set at both ends.
· Enable FastStart for non-Avaya IP Phones: Default = Off
A fast connection procedure. Reduces the number of messages that need to be exchanged before an audio channel is
created.

Not supported by Avaya Branch Gateway.
