More detailed information about how to configure the codec to answer and route multiple
sessionless ISDN calls is available in
Using ISDN Answer Routes for Sessionless ISDN Calls
. This
uses examples to explain how to set up consistent deterministic routing of multiple incoming
sessionless calls.
Answering both Tieline Session and Sessionless ISDN Calls
Leave the
Sessionless Only
check-box in the
ISDN Answering Config
unchecked if the codec is
expected to receive ISDN calls from Tieline codecs, or both Tieline and non-Tieline codecs (i.e. you
are not sure which type of codec may call). In this mode, when the codec answers a call it initially
expects to receive Tieline session data from the dialing codec and configure its own algorithm
settings according to that. If it fails to receive Tieline session data within 5 seconds (i.e. a non-
Tieline codec is calling, or a Tieline codec with session data disabled), it will use the settings in the
ISDN Answering Config
instead.
The following image displays how the answering codec will behave in this mode when receiving calls
from both Tieline and non-Tieline codecs.
Allow Answering of Sessionless ISDN Calls Only
Select
Sessionless Only
when answering ISDN calls from non-Tieline codecs only. When
Sessionless Only
is selected, the codec will not wait to receive the Tieline session data. This
reduces the time taken to answer an inbound sessionless call.
The following image displays how the answering codec will respond with
Sessionless Only
selected, i.e. calls from both Tieline and non-Tieline codecs are always regarded as sessionless.
