The
Ambiguous Call Processing
setting determines how calls are
to be processed when sufficient call data is not available to evaluate a
particular call against a Policy Rule. Select one of the following
options:
Skip the Rule
—If an ambiguous call is encountered, the Rule is
skipped, and processing continues with the next Rule.
Skip the Rule only on an inbound call
—If an ambiguous call
is encountered during an inbound call, the Rule is skipped and
processing continues with the next Rule in the Policy. When an
ambiguous call is encountered during an outbound call, the Policy
stops executing and no Tracks (except logging) are executed.
Inbound calls are distinguished from outbound calls because call
logs from the local PBX (SMDR) can be used to resolve outbound
calls that were ambiguous because the source phone number was
unavailable during the call. When SMDR data is available to
provide the source number, the outbound call is again processed
against the Policy and any applicable Tracks are executed.
Do not skip the Rule
—If an ambiguous call is encountered
during any call, the Policy stops executing and no Tracks (except
logging) are executed. If SMDR is in use, outbound calls that were
ambiguous due to missing source number are reprocessed against
the Policy when SMDR data is available to provide the source, and
any applicable Tracks are executed.
