[nsp] About restrictions

[Nekhoroshkov Dmitry]

Nice day, eh ?

I do appreciate it if someone can help me to solve this problem or gives me a hint ...
I have C827-4V with 4 FXS ports .
Voice configuration looks like this:

dial-peer voice 1 pots
 destination-pattern 101
 port 1
!
dial-peer voice 2 pots
 destination-pattern 102
 port 2
!
dial-peer voice 3 pots
 destination-pattern 103
 port 3
!
dial-peer voice 4 pots
 destination-pattern 104
 port 4
!
dial-peer voice 10 voip
 destination-pattern .T
 session target ipv4:X.X.X.X
 codec g711alaw

As you see all voip-calls go to X.X.X.X without restrictions .
I mean that every dialed pattern from FXSes goes to voip leg (except 101,102,103,104 of course).

Is it possible to implement such restrictions as I show below :
- to allow FXSes on port 1&2 to dial everything except 8.T ;
- to allow FXSes on port 3&4 to dial everything without exceptions .

Sorry for my poor English :-)
Thanks in advance !
Cheerio !
