SARK UCS/MVP Trunk Change Panel

_SARK UCS/MVP _ Trunk Change Panel is the place where trunk instances are modified.

FAX:

Description - Tick box. Defines whether FAX detection is enabled for this trunk. This is only valid for analogue zaptel trunks. It is ignored for SIP/IAX trunks.
Permissable values - Boolean.
default - Off.

LCL:

Description - Tick box. Local lookaside. Indicates that this trunk connects to a peer server on the same LAN. Calls placed on this trunk will not be subject to the VOIPMAX choke. It is used to carry local extension traffic between servers and to load balance outbound calls across a team of local servers each of which owns shared physical VOIP or Analogue resources. LCL Trunks should be placed in your route{s} as primary paths for extension traffic and as failover paths for outbound load balancing.
Permissable values - Boolean.
default - Off.
Note - Care should be exercised in nominating LCL trunks. SAIL will not check that the trunk end-address is truly local. This could lead to a WAN VOIP path being overloaded if you erroneously nominate a remote server as LCL.

ACT:

Description - Tick box. Defines whether this trunk is enabled. When turned off this Trunk will take no part in configuration.
Permissable values - Boolean.
default - On.

OPEN Inbound Route:

Description - Dropdown of all valid destinations on the system.
Permissable values - Any drop-down item.
Default - None

Trunk Pre-Select

Description - two digit numeric string which will bypass routing on outbound dial and select this trunk ONLY.
Permissable values - Any valid two-digit numeric string.
Default - None
Note - Avoid using emergency or significant number pairs such as 99, 11, or 91.

Transformation mask

Description - one or more colon-separated pairs of match/substitution digits separated by whitespace. Mask are evaluated sequentially beginning with the leftmost mask and proceeding to the right.
Permissable values - One or more pairs of valid numeric strings, separated by a colon. Masks are separated by whitespace. A null on either side of the expression is acceptable and results in suppression or addition.
Default - None
Example - Transformation masks are used to modify numbers before they are presented to the carrier. The value on the left of the colon will be substituted by the value on the right precisely once if it exists at the beginning of the dialled number at run-time. An example - let's take regularly dialled UK numbers and prepare them for presentation to a Carrier who requires E164 numbers.

• example 1 - dialled national UK number is 01924918076. Transformation mask is 0:44. Output number is 441924918076. Notice only the leftmost zero is replaced.
• example 2 - dialled international UK number is 0015136622300. Transformation mask is 00: Ouput number is 15136622300. Notice the use of a Null on the right-hand side of the transform results in a suppresion, or subtraction of the masked digit(s).
• N.B. order is important. Masks are sequentially applied from left to right. We need to use both of the above masks if we are to cover all UK possibilities. The order needs to be 00: 0:44 otherwise we will get incorrect results - if we specified 0:44 00: then international numbers would be converted incorrectly.
• example 3 - Astratel requires area code to be presented to it. In the Sydney area this is always 02. Sydney short numbers are 8 digits in length beginning 8 or 9. A dual mask of 8:028 9:029 will automatically prepend the 02 code so the user only need dial the 8 digit short form of the number. However astratel to astratel calls DO NOT require the 02 so for astratel numbers (8888XXXX), the 02 needs to be stripped off again so the final mask is 8:028 9:029 028888:8888.

Note 1 - Transformation masks are also useful for converting local numbers to foreign formats for presentation to offshore carriers.

Registration String:

Description - The substituted Registration template from the carrier entry.
Permissable values - A valid registration string with the keywords username and password if required. These keywords will be automatically replaced by the actual username and password when the trunk(s) is/are instantiated.
Default - None
Example username:password/byo.engin.com.au/username

CLOSED Inbound Route:

Description - Dropdown of all valid destinations on the system.
Permissable values - Any drop-down item.
Default - None
Note - Only valid if closed time segments exist (see automation).

DISA password:

Description - Password for DISA users to gain access to dial tone
Permissable values - Any valid n digit number.
Default - None

Cluster:

Description - Cluster Dropdown
Permissable values - Any drop-down item.
Default - Default Cluster.
Note - This field is essential when the alias outcome is either Operator or Voicemail, as it determines which Operator and Voicemail to use, as specified by the cluster operator.

Tag.

Description - Value to load into the CLID(Name) field immediately before the dial.
Permissable values - Any string.
Default - Empty.
Note - Used to present additional significant information about the call.

Inbound Prefix.

Description - Numeric Value to add to the CLID on inbound (usually the NDD).
Permissable values - Any numeric string.
Default - Empty.
Note - Used to present a "dialable" CLID when the carrier omits to present NDD.

Outbound CLID.

Description - CLID to present to the carrier on outbound calls.
Permissable values - Any numeric string.
Default - Empty.
Note - May not be honoured by the carrier. Consult your local calling regulations and carrier.

Music On Hold.

Description - Drop Down. Select ring tone or MOH on inbound call.
Permissable values - YES|NO.
Default - NO.

Monitor.

Description - Drop Down. Select whether this resource is to be monitored.
Permissable values - YES|NO.
Default - NO.

Alert-Info.

Description - Value to load into the SIP Header immediately before the dial.
Permissable values - Any string.
Default - Empty.
Note - There is no standard for Alert-Info strings. Consult your phone manufacturer's documentation for your specific device range.

Freeform PEER and USER Templates

Description - scrolling window of SIP/IAX.conf tuples.
Permissable values - Base entries are copied from the Carrier definition. The system automatically substitutes username and password with the corresponding items for this trunk. Any valid SIP or IAX user/peer tuple(s) can be added or modified. Each tuple should be terminated with a single carriage return.
Default - System provided
Note - It is not usually necessary to change these entries. As a general rule you should attempt to run without modifications unless/until you can prove otherwise.
