Function of Toll List/Pfx Mrk in Route Pattern when dialing international

[telecomadmin12]

I am having trouble with understanding the configuration of one of my route patterns, which is used for international calling. I have entries under Pfx Mrk (prefix 2) and Toll list (toll list 1). I don't understand what differences these entries make when dialing a 15-digit international number. List trace shows the extact same outpulse tone when these entries are removed and calling works just fine.
Does the system look at a toll list 1 before picking a trunk group?
Please explain.
SCCAN? n Secure SIP? n

3: 6 7 2 1

And thanks for your help again

Any ideas?

The prefix marks only affect calls set up as either FNPA or HNPA in ARS Analysis. The toll list wouldn't apply to intl calls either, but it doesn't use that for trunk selection anyway. That is used to determine if a call can be placed by a station that has tac-toll or all-toll restrictions in their COR. My guess is whoever set up that route pattern just copied an existing long distance route pattern and bumped up the FRL requirement.

Thanks a lot for the answer, very helpful.
I am still unsure about the toll list entry in the route pattern. I think I know how toll restriction works. You set calling party restriction to all toll and enter something at unrestricted call list, then change toll and enter the numbers you want the COR to be able to call.
But how would the toll entry in the route pattern affect this? When I leave it blank it just does the same as when entered.

There is a command "change ars toll x:yyy". The x tells the system which toll list to look at (in your example, 1) and the yyy says what 100-number range of prefixes to bring up. So, "change ars toll 1:200" would bring up toll list 1 with all the prefixes from 200-299. Each one will have a y or n telling the system if it is a toll call or not . You then have to keep up with any changes to all the prefixes from 200-999 if they ever change from a free call to a toll call.

Thank you again.
Are these yyy prefixes the first digits of the number I am dialing (or Area Codes, e.g.)?
And whether a call is toll or toll free would depend on the number I am dialing and on the provider,right? So how would an entry in the change ars toll x:yyy set to either y or n actually influence the call and its routing? Or is that ars toll a way to keep track of my toll calls somehow and see how many there were made or something or rather a way of restricting calls?
Many questions here but thanks for your patience.

It's the prefix, or office code, not area code. i.e. xxx-yyy-zzzz, xxx being the area code. It doesn't affect the routing, as in which trunk group to use. It's just there to prevent callers with tac-toll or all-toll restrictions in their COR from making that call, and depending on the prefix mark used, it can automatically insert or delete a 1 and/or the NPA (area code)assigned in that line in the route pattern.. It's also not used to track calls, at least that I know of.

Thanks again.
I still don't get it entirely but I am getting there.
I have set a COR to Calling Party restriction all toll. Then I have to enter a number in unrestricted call list. I choose 1. Then I go to change toll xxx and enter the first few digits of the number I want to allow and make an x at unrestricted call list 1. Removing the x would disallow the number to be dialed from a station with COR all toll restriction.
But how would I deny a number through that change ars toll...?
Could you give me an example with let's say number 1212 873 4567? What would I do to deny it through change ARS toll?
I guess the 873 would be the prefix, right? Would change ars toll 1:873 take me further?
You see I am still a bit lost here.
My route pattern for that number has 1 entered under Toll list and no entry under NPA.
