the current dialed string entry matches the
<dial-pattern>
preceding the marker. A
<block-
access-marker> at the end of the <dial-pattern> directs the phone to immediately cancel
the outbound call with reorder tone, if the current dialed string entry matches the
<dial-
pattern>
preceding the marker.
Prefix and suffix operations are applied at the time of call initiation, and only if the <dial-
pattern>
matches the dialed string entry.
If the leading characters of the dialed string entry matches the prefix pattern preceding the
“|” , then the leading characters of the dialed string entry are replaced by the substring
following the
“|”
. If the prefix pattern preceding the
“|”
is null, then the substring
following the
“|”
are inserted at the beginning of the dialed string entry. If the substring
following the “|” is null, then the leading characters of the dialed string entry are deleted.
If the trailing characters of the dialed string entry match the suffix pattern preceding the
“|” , then the trailing characters of the dialed string entry are replaced by the substring
following the “|” and preceding any <meta-operation>. If the suffix pattern preceding the
“|”
is null, then the substring following the
“|”
and preceding any
<meta-operation>
are
inserted at the end of the dialed string entry. If the substring following the “|” and
preceding any <meta-operation> is null, then the trailing characters of the dialed string
entry are deleted.

Meta operations construct message headers that meet MLPP requirements.
The
<meta-operation>
includes the following combinations:
•
<priority-id>
• <rph-id>
•
<cal-id>
•
<priority-id> , <cal-id>
• <rph-id>
,
<cal-id>
If the
<suffix-operation>
includes a
<priority-id>
, then the phone displays the r-priority
identified by the second digit of the dialed string entry. If the <suffix-operation> includes an
<rph-id> , then the phone displays the r-priority and includes a Resource Priority Header
(RPH) in the outgoing INVITE. The RPH includes the network domain identified by the
<priority-index> and the r-priority identified by the second digit of the dialed string entry.
If the <suffix-operation> includes a <cal-mode-id> , then the phone includes a Confidential
Access Level (CAL) header in the outgoing INVITE. The CAL header includes the mode
identified by the <cal-mode-id> and the access level identified by the <access-level> .
<priority-index> is used to select a namespace associated with <priority-id> and <rph-
id>
. Predefined namespaces are selected with the following
<priority-index>
values:
•
0 selects the “dsn” namespace
•
1 selects the “q735” namespace
•
2 selects the “uc” namespace
