31.6.2 Configuring ISDN Answering
ISDN Answer Configs are used to determine how codec ISDN modules will behave when
answering ISDN calls.
The following image explains the difference between answering calls from Tieline codecs sending
session data, and non-Tieline codecs making sessionless ISDN calls. Codecs sending Tieline
Session Data contain all the information required to connect, e.g. algorithm and audio stream
routing settings. When answering sessionless calls it is necessary to configure the answering
codec with an ISDN Answer Config, which tells the answering codec how a sessionless call will
try and connect.
After installing a ViA ISDN module it is possible to save up to two different ISDN Answer Configs,
which allow each ISDN B channel to be individually configured for unique answering behaviors. ISDN
answering can be configured to suit:
·
Hardware available in the codec, i.e. the number of B channels available.
·
Expected dialing behaviors, e.g. if B channels should bond or not, and whether audio streams
need to use Dial and Answer Route tags.
·
The type of call being received by the codec, e.g. Tieline (with Tieline Session Data) versus
non-Tieline sessionless calls.
·
The algorithm expected when receiving sessionless calls.
The two available Configs allow you to select which B channel or channels are used to answer a
call or calls from incoming ISDN codecs.
