h323AttributesInformationTransferCapability

Indicates the type of calls made by the H.323 unit. This value is used to set the
information transfer capability field of the bearer capability element of the SETUP
message (Q.931 header).
          
This information may help the called endpoint to take actions based on the nature of the
media stream to be established (voice-only call or data call or video call). This
information may impact the called endpoint on its decision to accept the call. For
example, a SCN gateway may not have access to enough bandwidth in order to accept a new IP
to SCN data call.
          
For calls between endpoints that are both on the IP network, this information may be
ignored by the called endpoint. This information is mostly used by SCN gateways and ISDN
gateways. The value of this variable should be changed only when necessary, in order to
adapt to third-party systems.
          
When receiving a call, this H.323 unit ignores the value of the information transfer
capability field.
          
speech                         : Indicates a voice-only call.
          
unrestrictedDigitalInformation : Unrestricted Digital Information (64 kbps). Indicates an
                                 audiovisual call.
          
restrictedDigitalInformation   : Restricted Digital Information (56 kbps). Indicates an
                                 audiovisual call.
          
audio31kHz                     : 3.1 kHz audio. Indicates a voice-only call.
          
udita                          : Unrestricted Digital Information with
                                 Tones/Announcements. Indicates an audiovisual call.
          
video                          : Indicates an audiovisual call.
          
'speech' and 'audio31kHz' are the choices that best represent the capabilities of this
H.323 unit.
          
Even though this H.323 unit does not support any video capability,
'unrestrictedDigitalInformation', 'restrictedDigitalInformation', 'udita' and 'video'
are provided in order to increase interoperability with third-party systems.
          
'unrestrictedDigitalInformation' is the default value for backward compatibility issues.
          
Please refer to ITU-T Recommendation Q.931 and ITU-T Recommendation H.225.0 for more
information on bearer capabilities.
