| IT Dept Takes Bigger Role In Company Telecom Decisions
I am running ver6.2 but will go through a couple of things that can be done.
One way to block extensions to external trunks is to bar trunk access at the TAC level.
1. You need to know what access code an Extension in question uses to get an outside line and associate this code with a trunk Main Group.
In most cases 0 (or whatever your access is) is used for outgoing calls. If you enter the command LTMG and enter C (for code) when prompted with group? And the enter 0 (or whatever your access is) when prompted for code?
Alternatively you can enter LTMG A to list all MG’s along with access code.
2. Next step is that you need to make sure that the TAC in question has access to the relevant MG.
To do this enter the command LTGA and when prompted for group? Type the MG number or A to list all. When prompted for zone? Enter 0 9or whatever your access is). The result of this command will show a table with TAC’s 00 to 31 listed on the top and the MG’s down the left side. If there is an N at the cross reference point between TAC and MG that means that a person with that TAC is NOT able to access these trunks and therefore can not make any outgoing calls over that link.
This can be changed by using the command RTGA - Revise Trunk Group Access.
It all depends if you want this to be permanent or on a case by case basis.
You can also go further on route restrictions and TAC levels.
3. Now that you have found out that the TAC in question does have access to a MG for outgoing calls you need to find what restrictions are in place, this is done using the command LACR. Enter the command LACR, when prompted for CODE? Enter the number dialled for outside line (0 or ?) and then enter the TAC you wish to check.
When you have entered this information it will come back advising of a Route Restriction Table (RRT) associated with the TAC attempting to make an outgoing call over a specific link.
4. To check what restrictions are in this RRT enter the command LRRT followed by the table which was obtained in step 3.
I have about six levels of TAC setup, with other multiple restrictions on what numbers are blocked completely like betting and competition lines are completely blocked.
Hope this helps if you have further questions I would be happy to help. |
