Web/EMS: Number of
Digits to Leave
[LeaveFromRight]
Defines the number of digits that you want to retain from the right of the
redirect number.
Web/EMS: Prefix to Add
[Prefix2Add]
Defines the number or string that you want added to the front of the
redirect number. For example, if you enter 9 and the redirect number is
1234, the new number is 91234.
Web/EMS: Suffix to Add
[Suffix2Add]
Defines the number or string that you want added to the end of the
redirect number. For example, if you enter 00 and the redirect number
is 1234, the new number is 123400.
Web: Presentation
EMS: Is Presentation
Restricted
[IsPresentationRestricted]
Enables caller ID.
 Not Configured = Privacy is determined according to the Caller ID
table (see Configuring Caller Display Information on page 268).
 [0] Allowed = Sends Caller ID information when a call is made using
these destination / source prefixes.
 [1] Restricted = Restricts Caller ID information for these prefixes.
Note: If 'Presentation' is set to 'Restricted' and the AssertedIdMode
parameter is set to 'P-Asserted', the From header in the INVITE
message includes the following: From: 'anonymous' <sip:
anonymous@anonymous.invalid> and 'privacy: id' header.
21.6 Mapping NPI/TON to SIP Phone-Context
The Phone-Context table page allows you to map Numbering Plan Indication (NPI) and
Type of Number (TON) to the SIP 'phone-context' parameter. The 'phone-context'
parameter appears in the standard SIP headers where a phone number is used (i.e.,
Request-URI, To, From, and Diversion). When a call is received from the Tel side, the NPI
and TON are compared against the table and the matching 'phone-context' value is used in
the outgoing SIP INVITE message. The same mapping occurs when an INVITE with a
'phone-context' parameter is received.
For example, for a Tel-to-IP call with NPI/TON set as E164 National (values 1/2), the
device sends the following SIP INVITE URI:
sip:12365432;phone-context= na.e.164.nt.com
This is configured for entry 3 in the figure below. In the opposite direction (IP-to-Tel call), if
the incoming INVITE contains this 'phone-context' (e.g. "phone-context= na.e.164.nt.com"),
the NPI/TON of the called number in the outgoing Setup message is changed to E164
National.
