DESCRIPTION
Enter the session expiry time in seconds for all phone connections on
this trunk The allowable range is 90~86400 seconds. This value cannot
be lower than the Minimum SE.
This allows the X6004 to automatically disconnect any phone calls on
this trunk after a certain period of inactivity.
This field displays the caller ID format shown to the callees depending
on the setting you configure in the CallerID Name & Number and
The Extension Prefix fields.
Specify the representative number shown as source caller ID to the
callees when you make external calls through this trunk connection.
The default is "zyxel".
Select the caller ID display format you want to use when you make
calls.
A caller ID consists of a call ID name (A), a caller ID number (B) and a
SIP server IP address (C). The caller ID has the following format:
"A"<B@C>.
The choices are:
(In the following examples, we assume a company representative
number is 12345678, their SIP server IP is 10.1.1.1, a caller extension
number is 1111 and DDI/DID number 12345555 can map to the
extension 1111.)
• Extension + Extension: Displays the caller's extension number in
A and B. For example, "1111"<1111@10.1.1.1>.
• Extension + Representative Num: Displays the caller's extension
number in A and the SIP trunk's representative number in B. For
example, "1111"<12345678@10.1.1.1>.
• Representative Num + Representative Num: Displays the SIP
trunk's representative number in A and B. For example,
"12345678"<12345678@10.1.1.1>. Select this format if you don't
want callees to know the caller's extension number.
• Extension + Representative Num (DDI/DID mapped):
Displays the caller's extension number in A and the SIP trunk's DDI/
DID mapped representative number in B. For example,
"1111"<12345555@10.1.1.1>.
• Representative Num (DDI/DID mapped) + Representative
Num (DDI/DID mapped): Displays the SIP trunk's DDI/DID
mapped representative number in both A and B. For example,
"12345555"<12345555@10.1.1.1>.
Specify whether to add a prefix number in the callerID name when you
make calls through this trunk connection. The availability of this setting
varies depending on the format of CallerID Name & Number you
selected.
