If “Self-Defined Tome Zone” is selected, please specify the time zone parameters in the “Self-Defined Time Zone” field as described in the below option.

Self-Defined Time Zone

If “Self-Defined Time Zone” is selected in the “Time Zone” option, users will need to define their own time zone following the format below.

The syntax is: std offset dst [offset], start [/time], end [/time]

Default is set to: MTZ+6MDT+5,M4.1.0,M11.1.0

MTZ+6MDT+5

This indicates a time zone with 6 hours offset and 1 hour ahead for DST, which is U.S central time. If it is positive (+), the local time zone is west of the Prime Meridian (A.K.A: International or Greenwich Meridian); If it is negative (-), the local time zone is east.

M4.1.0,M11.1.0

The 1st number indicates Month: 1,2,3.., 12 (for Jan, Feb, .., Dec).

The 2nd number indicates the nth iteration of the weekday: (1st Sunday,

3rd Tuesday…). Normally 1, 2, 3, 4 are used. If 5 is used, it means the last iteration of the weekday.

The 3rd number indicates weekday: 0,1,2,..,6 ( for Sun, Mon, Tues, … ,Sat).

Therefore, this example is the DST which starts on the First Sunday of

April to the 1st Sunday of November.

Calling Rule Name

Configure the name of the calling rule (e.g., local, long-distance, etc). Letters, digits, _, and – are allowed.

Pattern

• All patterns are prefixed with the “_”.
• Special characters:

X: Any Digit from 0-9.

Z: Any Digit from 1-9.

N: Any Digit from 2-9.

“.“: Wildcard. Match one or more characters.

“!“: Wildcard. Match zero or more characters immediately.

Example: [12345–9] – Any digit from 1 to 9.

Notes:

• Multiple patterns can be used. Each pattern should be entered in new line.
• Example:

_X.

_NNXXNXXXXX

_818X.

Enable Filter on Source Caller ID

When enabled, users could specify extensions allowed to use this outbound route. “Privilege Level” is automatically disabled if using “Enable Filter on Source Caller ID”.

The following two methods can be used at the same time to define the extensions as the source caller ID.

1. Select available extensions/extension groups from the left to the right. This allows users to specify arbitrary single extensions available in the PBX.
2. Custom Dynamic Route: define the pattern for the source caller ID. This allows users to define extension range instead of selecting them one by one.

Main Trunk

Trunk

Select the trunk for this outbound rule.

Strip

Allows the user to specify the number of digits that will be stripped from the beginning of the dialed string before the call is placed via the selected trunk.

Example:

The users will dial 9 as the first digit of long-distance calls. However, 9 should not be sent out via digital lines and the PSTN line. In this case, 1 digit should be stripped before the call is placed.

Prepend

Specify the digits to be prepended before the call is placed via the trunk. Those digits will be prepended after the dialing number is stripped.

Failover Trunk

Trunk

Failover trunks can be used to make sure that a call goes through an alternate route when the primary trunk is busy or down. If “Use Failover Trunk” is enabled and “Failover trunk” is defined, the calls that cannot be placed via the regular trunk may have a secondary trunk to go through.

GXW450X supports up to 10 failover trunks.

Example: The user’s primary trunk is a VoIP trunk and the user would like to use the PSTN when the VoIP trunk is not available. The PSTN trunk can be configured as the failover trunk of the VoIP trunk.

Strip

Allows the user to specify the number of digits that will be stripped from the beginning of the dialed string before the call is placed via the selected trunk.

Example:

The users will dial 9 as the first digit of long-distance calls. However, 9 should not be sent out via digital lines and the PSTN line. In this case, 1 digit should be stripped before the call is placed.

Prepend

Specify the digits to be prepended before the call is placed via the trunk. Those digits will be prepended after the dialing number is stripped.

Time Condition

Time Condition Mode

Use Main Trunk or Failover Trunk: Use the Main Trunk and its settings during the configured time conditions. If the main trunk is unavailable, the Failover Trunk and its settings will be used instead.

Use Specific Trunks: Use specific trunks during the configured time conditions. The Strip and Prepend settings of the Main Trunk will be used. If a trunk is unavailable during its time condition, no failover trunks will be used.

Time Condition

Users could customize holiday time, office time, or a specified time to allow the outbound route to be used.

Trunks

Select the trunk to configure the inbound rule.

Pattern

• All patterns are prefixed with the “_”.
• Special characters:

X: Any Digit from 0-9.

Z: Any Digit from 1-9.

N: Any Digit from 2-9.

“.“: Wildcard. Match one or more characters.

“!“: Wildcard. Match zero or more characters immediately.

Example: [12345-9] – Any digit from 1 to 9.

N … Any digit from 2-9.

. … Wildcard, matching one or more characters.

! … Wildcard, matching zero or more characters immediately.

X … Any digit from 0-9.

Z … Any digit from 1-9.

– … Hyphen is to connect characters and it will be ignored.

[] Contain special characters ([x], [n], [z]) represent letters x, n, z.

Set Caller ID Info

CalleID Number

Configures the pattern-matching format to manipulate the numbers of incoming callers or to set a fixed callerID number for calls that go through this inbound route.

• ${CALLERID(num)}: Default value which indicates the number of an incoming caller (CID). The CID will not be modified.
• ${CALLERID(num):n}: Skips the first n characters of a CID number, where n is a number.
• ${CALLERID(num):-n}: Takes the last n characters of a CID number, where n is a number.
• ${CALLERID(num):s:n}: Takes n characters of a CID number starting from s+1, where n is a number and s is a character position (e.g. ${CALLERID(num):2:7} takes 7 characters after the second character of a CID number).

n${CALLERID(num)}: Prepends n to a CID number, where n is a number.

CallerID Name

Default string is ${CALLERID(name)} which means the name of a incoming caller, it’s a pattern-matching syntax format.

A${CALLERID(name)}B means Prepend a character ‘A’ and suffix a character ‘B’ to ${CALLERID(name)}.

Not using pattern-matching syntax means setting fix name to incoming caller.
