DID Argument Details

Use Remainder. Specifies whether a particular part, i.e. the remainder, of the inbound number will be used to form a part of the outbound number.

For a remainder to become non-zero a specified inbound Prefix has to match the first part and/or a specified inbound Suffix has to match the last part of an inbound number, however individually or combinations of both never fully match the complete inbound number.

Both inbound Prefix and Suffix can be defined under Dialplan entry details. When Use Remainder, is active the previously mentioned “remainder” will be appended to and precede the Prefix and the Suffix of the outbound number, respectively. The outbound Prefix and Suffix precede and append, respectively, the “remainder” as to form the complete outbound number.

The latter prefix and suffix can be defined under Arguments. Prefixes and suffixes are standard parameters of dial plans.

Suppose, as an example, in the Dialplan entry details the inbound Prefix equals 9876 and inbound suffix equals 54. In the Arguments settings the outbond prefix equals 1234. For an inbound connection to phone number 9876154 the 3G Gateway will strip the prefix 9876 and the suffix 54 from the called number, hence the remainder equals 1. For the outbound connection the 3G Gateway will add the prefix (configured in arguments) in front of the remainder, hence the outbound number equals 12341.

For the same settings with an inbound number 9876254 results in an outbound number 12342. In case the prefix and/or suffix fully match the inbound number the remainder will be empty and the useremainder value will be ignored.

Suffix. Specifies the last part, i.e. the part			Prefix. Specifies the first part, i.e. the part

Net type. Either H.324m, H.323 or SIP of the outbound call.

AV mode. This mode determines the outbound audio and video call settings. It is either Audio Only, Audio + Video, Auto(matic) no fallback to audio, Auto + fallback to audio and Auto + always fallback to audio.

•In the Audio Only mode a voice call is being setup, even when all endpoints support both audio and video capabilities. Note that this setting will be overruled in case Allow Forwarding is set to Yes and both endpoints possess audio and video capabilities.

•In the Audio + Video mode a call is only being setup when endpoints support both audio and video capabilities and a call with both these capabilities can be set up.

•In the Auto mode a call is being setup according to the capabilities of the endpoints. Of the latter, 3 versions can be distinguished: no fallback to audio, fallback to audio or always fallback to audio.

•In the no fallback to audio case either an audio

+video or an audio only call is being setup, depending on the capabilities choice of the initiating endpoint, i.e. when an audio + video call is being set up, whereas the receiving endpoint only supports audio, the call is terminated.

•In the fallback to audio case capabilities can be changed to an audio only call when the receiving endpoint supports only audio, even when an audio + video call is being set up by the initiating endpoint.

•The always fallback to audio case is used in case the telephony switch interferes or cannot handle capability renegotiation, therefore when an audio

+video call fails automatically an audio call will be set up.
