ASAI and Call Routing
7-8 Issue 7 May 1998
specific_event [optional] This parameter indicates when the
tone detector used by the ASAI-Requested Digit
Collection feature should be released. Options
are “far end answer/connect” and “party
disconnect.” Only the “far end answer” option is
currently supported (starting with Release
G3V3); other values are rejected. When the
event option is not present in the Route Select
and the digit collection is specified, the default is
“far end answer/connect.”
number_of_digits [optional] This parameter indicates the total
number of digits that will be collected (1 to 24).
For ASAI-Requested Digit Collection, every “#”
and “*” count as one digit each. If the request is
not in the valid range, the Route Select fails with
cause CS0/79 — Service/option not available.
digit_coll_timeout [optional] This parameter indicates how many
seconds (1 to 31) the tone detector will continue
to collect digits after the first digit is received for
ASAI-Requested Digit Collection. The default is
no timeout.
uui_info [optional] If an ASAI adjunct provides UUI in a
Route Select, then the ECS stores that UUI with
the call. The UUI overwrites any previous UUI
stored with the call.
UUI from a Route Select will be sent in any ISDN
SETUP message for the call, in the Alerting and
Call Offered Event Reports, or in a future Route
Request.
The UUI IE sent over an ISDN trunk can contain
more data than the UUI IE sent to ASAI. This
happens when the ISDN trunk group is
administered with supplementary service
protocol other than B, and the UUI IE Treatment
is set to “shared”. The UUI for ASAI is packed
within the shared UUI before it is sent over an
ISDN trunk, and is unpacked at the other end.
