H.323 Protocol Parameters

Use the following parameters to do the following:
  • Configure SIP and H.323 protocols.
  • Set up a SIP and H.323 dial plan.
  • Set up manual protocol routing using soft keys.

    If the protocol to place a call cannot be determined, the Use SIP and Use H.323 soft keys display, and users must select one to place the call.

  • Configure auto-answering on H.323 calls only.
  • Set the preferred protocol to SIP.
  • Set to configure one SIP line, one H.323 line, and a dual protocol line—both SIP and H.323 can be used.
  • Set the preferred protocol for off-hook calls on the third (dual protocol) line to SIP.

H.323 is supported only on Poly Trio systems.

up.manualProtocolRouting

Specifies whether to choose a protocol routing or use a default protocol.

1 (Default) - User is presented with a protocol routing choice in situations where a call can be placed using either protocol (for example, with SIP and H.323 protocols).

0 - Default protocol is used.

up.manualProtocolRouting.softKeys

Display soft keys that control Manual Protocol Routing options.

1 (Default) - Soft keys are enabled. Use soft keys to choose between the SIP or H.323 protocol.

0 - Soft keys for protocol routing do not display.

call.autoAnswer.H323

Enables and disables auto-answer for H.323 calls.

0 (default) - Disabled

1 - Enabled

call.enableOnNotRegistered

Enable or disable calls on the phone when it is not registered. When enabled, the phones can make calls using the H.323 protocol even though an H.323 gatekeeper is not configured.

Lync Base Profile – 0 (default)

Generic Base Profile – 1 (default)

1 - Enabled

0 - Disabled

Change causes system to restart or reboot.

call.autoAnswer.videoMute

0 (default) - Video begins transmitting (video Tx) automatically after a call is auto-answered.

call.autoRouting.preferredProtocol

SIP (default) - Calls are placed via SIP if available or via H.323 if SIP is not available.

H323 - Calls are placed via H.323 if available, or via SIP if H.323 is not available.

call.autoRouting.preference

line - Calls are placed via the first available line, regardless of its protocol capabilities. If the first available line has both SIP and H.323 capabilities, the preferred protocol is used ( call.autoRouting.preferredProtocol).

protocol - The first available line with the preferred protocol activated is used, if available. If not available, the first available line is used. Note that auto-routing is used when manual routing selection features ( up.manualProtocolRouting) are disabled.

reg.x.protocol.H323

Enable or disable H.323 signalling for registration x.

0 (default) - Disabled

1 - Enabled

reg.x.server.H323.y.address

Address of the H.323 gatekeeper.

Null (default)

IP address or hostname

reg.x.server.H323.y.port

Port to be used for H.323 signaling. If set to Null, 1719 (H.323 RAS signaling) is used.

0 (default)

0 to 65535

reg.x.server.H323.y.expires

Desired registration period.

3600

positive integer

voIpProt.H323.autoGateKeeperDiscovery

1 (default) - The phone will attempt to discover an H.323 gatekeeper address via the standard multicast technique, provided that a statically configured gatekeeper address is not available.

0 - The phone will not send out any gatekeeper discovery messages.

Change causes system to restart or reboot.

voIpProt.H323.blockFacilityOnStartH245

0 (default) - Facility messages when using H.245 are not removed.

1 - Facility messages when using H.245 are removed.

Change causes system to restart or reboot.

voIpProt.H323.dtmfViaSignaling.enabled

Enable or disable use of H.323 signaling channel for DTMF key press transmission.

1 (default) - Enabled

0 - Disabled

Change causes system to restart or reboot.

voIpProt.H323.dtmfViaSignaling.H245alphanumericMode

1 (default) - The phone supports H.245 signaling channel alphanumeric mode DTMF transmission.

0 - The phone does not support H.245 signaling channel alphanumeric mode DTMF transmission

Note: If both alphanumeric and signal modes can be used, the phone gives priority to DTMF.

Change causes system to restart or reboot.

voIpProt.H323.dtmfViaSignaling.H245signalMode

1 (default) - The phone will support H.245 signaling channel signal mode DTMF transmission.

0 - The phone will not support H.245 signaling channel signal mode DTMF transmission.

Change causes system to restart or reboot.

voIpProt.H323.enable

0 (default) - The H.323 protocol is not used for call routing, dial plan, DTMF, and URL dialing.

1 - The H.323 protocol is used for call routing, dial plan, DTMF, and URL dialing.

Change causes system to restart or reboot.

voIpProt.H323.local.port

Local port for sending and receiving H.323 signaling packets.

0 - 1720 is used for the local port but is not advertised in the H.323 signaling.

0 to 65535 - The value is used for the local port and it is advertised in the H.323 signaling.

Change causes system to restart or reboot.

voIpProt.H323.local.RAS.port

Specifies the local port value for RAS signaling.

1719 (default)

1 to 65535

Change causes system to restart or reboot.

voIpProt.server.H323.x.address

Specify the address of the H.323 gatekeeper. Only one H.323 gatekeeper per phone is supported. If more than one is configured, only the first is used.

Null (default)

IP address or hostname

voIpProt.server.H323.x.port

Designate a port to be used for H.323 signaling. The H.323 gatekeeper RAS signaling uses UDP, while the H.225/245 signaling uses TCP.

1719 (default)

0 to 65535

voIpProt.server.H323.x.expires

Set a desired registration period.

3600 (default)

positive integer.

sec.H235.mediaEncryption.enabled

sec.H235.mediaEncryption.require

0 (default) - The media encryption requirement is not required.

1 - If sec.H235.mediaEncryption.enabled is also set to 1, media encryption negotiations are initiated or completed with the far end, but if negotiations fail, the call is dropped.
