Nice resource, ghtrout! Apologies to all, I am inspired once again to repeat the poem:
If the TGAR on the set
Matches the TARG on the route,
You can try and try and try
But your call just WON'T go out!
Seriously, I think you might also want to look into FCR tables, if you have zone paging. If you create a table (LD 49) and allow 0-9 or whatever zones you have, then you apply that table to the FRL prompts in your route, CTD users can then dial the access code for the route followed by whatever digit represents that zone. I am traveling today but can post the specifics for you later, if you need them.
