Note:
The conditions of this command are as follows.
• Assign this command adjusting to the specifications on the SIP network where MG-SIP128 [MG-
128SIPMGG] connects.
• Select 2 when the caller ID blocking is judged by the userinfo in From header on the SIP network side spec-
ification.
e.g.) From: "01234567" <sip:anonymous@anonymous.invalid>
• Do not select 2 when the caller ID blocking is assigned by Displayname only on the SIP network side.
e.g.) From: "Anonymous" <sip:01234567@xxx.com> In this case, the cpn is informed when 2 is
selected.
• Numbers from 0 to 9, *, or # can only be obtained as a calling party number. When any other characters are
contained in the calling party number, the order of priority will shift to the next precedence.
However, if any characters other than the ones indicated above are detected in Displayname, the next and
later priority will be disregarded and the cpn will be handled as blocked.
e.g.) From: "0123ABC" <sip:01234567@xxx.com> In this case, the cpn will be handled as
blocked when 0 is selected.
