How do you use TACs?

[9mmgeek]

I have the TACs defined in my PRI trunks. They are not CBC trunks. The TACs are in a range defined as DACs in the dialplan.

I cannot figure out how to actually use a trunk when dialing. I don't see any intuitive feature access codes or anything in COS or COR that would restrict or allow usage of the TACs. It seems like you should just dial the TAC since it is in the dial plan.

Any guidance would be appreciated.

you would need to define it in your ARS table. I don't know what you are trying to accomplish exactly, but if you are at an lsp site for example, you would need to add a location, and then issue the command change ars analysis location X, where x is the number of your new location. This then allows you to select which trunk/route pattern you would like to use when dialing certain digits from that location.

PRI's cannot be accessed via TAC codes, period.

You must have an ARS route to the trunk group to access it. POTS lines, and TIE trunks can usually be access by TAC codes, if you allow it on the 'trunk group' (page 1, "Dial Access?")

Thanks all,

I had read about it not working on PRIs in an old manual and asked the forum. Someone said it would not work on CBC trunks so I thought it would work on my public trunks.

The problem is that we are using ARS now and one site is having problems when their calls get routed through another site. They have trouble navigating menus in another company's conference center. It literally reads back the conference information differently than they entered it. I do the same thing from my site and it works fine.

We have not been able to figure out what is wrong with their network that would cause this. No packet loss and minor jitter. If you have any ideas on that problem I'd appreciate it.

For now I put an entry in their ARS table for this specific number so it uses their PRI and their problem goes away. I was trying to give them a way to override ARS manually and use their local PRI when the ARS selected link does not work for them.

you can do that, use the "aar code", then in the aar analysis, setup a "1", + 10 digit entry, set it to use whatever route you want when they dial the AAR code.

This will give you an alternate way to dial any number via a different, or backup route, from the ars tables.

so for example, if you aar code was "8", you would dial "8-1-xxx-yyy-zzzz" and it would be routed through aar analysis and match your "1" + 10 digit entry, and route to whatever route you have configured for that.

Yes, i actually just set this up. if you are looking to dial out the local T1, you have to set up specific ars table for that location.

ch locations

you will see the different locations listed. add the location you want to change, with the specific prefix. Then:

ch ars an loc X

and you have a specific ars table for that location, and you can then choose the trunk numbe of the local T1 for all your entries, ensuring that the location uses the local T1.

If you want a backup, then you need to define a new route pattern with your backup trunks, and point the local ars to that route pattern. then the system will choose the trunks in order of succession.

just an addendum to this post, i left one step out. When you change ars anlaysis for location x, you need to point it at a route pattern that has the trunk that you would like to use listed first.
