Toll restriction problems on SV8500

I'm trying to make something work but for some reason I can't seem to be able to, and I'm hoping I'm only missing something minor that someone might be able to point out.

Here, we have an asterisk phone system connected to our 8500 via ISDN PRI. We have calls going between the 2 systems no problem, from any extension to any extension.

What I'm trying to accomplish is that from the 8500, I'm trying to send some long-distance calls out on this route to asterisk, but not all and only from certain RSC phones. This is so that asterisk then can do some processing of those calls and send them out to another carrier.

At the same time, I want to maintain the calling of stations between the 2 phone systems.

Currently, an ARSC table allows calls from all RSC phones (the whole table is "1") to the asterisk system. But as soon as I change in that table the "1" to "2" for a given RSC under RRI-3, none of the calls go through, not even station-to-station. Which is probably fine because now I'm supposed to go to ATDP and enable calls on that route to numbers starting with certain digits. But this is where the problem starts, as I can't seem to figure out how to enable calls to numbers starting with certain digits.

No matter how many digits and in what way I enter, the call attempts remain blocked. In ATDP, I enter the following:

TDM/OG=OG
Day/Night=Day mode
RSC=3 (the rsc of the phone I'm testing it with)
OG RT=135 (the ISDN route going to asterisk)
DC= 3 (I also tried 32 and 321 as this the beginning digits of extensions on asterisk)
TDI=1

Yet, after this, I still can't complete any calls on that route to asterisk. I tried the above with ATDPL and ATDPN but none of those worked either.

What I'm thinking might be wrong (but I'm just guessing and I'm still going through the manuals) is that this route between the 2 phone systems is somehow defined differently with ARTD (like a tie-trunk? as opposed to an outgoing toll-trunk).

Anybody has any ideas on this?
 
This was resolved. There is a very tricky twist to the ATDP command, where, if you want to allow a certain digit to be dialed by a certain RSC on a certain route, you have to enter not just the digits that you want to allow, but you have to prefix those digits with the digit defined in ARNP for that route.

If you want to allow numbers for 818 area code with ATDP for RSC 4 on route 10, and you defined "1" in ARNP for route 10, then this is what you enter into DC for ATDP:
User dials 9-1-818-xxx-xxxx
-OPR strips the beginning 9 which the phone company doesn't need
-That leaves 1-818-xxx-xxxx
-Prefix that with 1 from ARNP
-You would enter 11818

At least this is how it worked for me. I got this information from my vendor who forwarded an internal-looking cheat-sheet to me. I went back to the Command Manual after I got this working, and found no trace of the above information. If it's there, I couldn't find it.
 
ARNP should have a 9 in it for all outgoing routes. The 9 covers all lower digits 1-8. If you have a 4 in ARNP, then it cover 1-4. Usually the system, when first programmed has the 9 there to cover all bases. In ATDP there should be a 9 in front of the numbers to be allowed or denied.
