Voip Lab PSTN one way calls

Recommended Posts

I have a voice lab that is set up like so:

CME------GW------PSTN
| | |
| | |
2001 3001 411

 

 

CME and GW are connected via ethernet, GW and PSTN are connected via 2 back to back vwic mft cards. Im using CME 8 on everything.
Everything seems to work ok, but i can call 411 from 2001, I can dial 411 from 3001, and i can even dial 2001 from 411....I'm not sure what the problem is but I think it's something on the dial peers or the voice port configs, here is what I got

CME
---
dial-peer voice 50 voip
destination-pattern 300.
session target ipv4:10.145.1.2
!
dial-peer voice 411 voip
destination-pattern 9...
session target ipv4:10.145.1.2

GW
--
interface Serial0/2/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn incoming-voice voice
no cdp enable
!
dial-peer voice 1 voip
destination-pattern 2...
session target ipv4:10.145.1.1
!
dial-peer voice 411 pots
destination-pattern 9...
port 0/2/0:23
forward-digits 0

PSTN
----
interface Serial0/1/0:23
no ip address
encapsulation hdlc
isdn switch-type primary-ni
isdn protocol-emulate network
isdn incoming-voice voice
no cdp enable

dial-peer voice 2000 pots
destination-pattern 2...
no digit-strip
port 0/1/0:23
!
dial-peer voice 3000 pots
destination-pattern 3...
no digit-strip
port 0/1/0:23

I can certainly post more of the config if needed, another thing that's bugging me is that when I dial 3001 or 2001 from 411 i get a dial tone and I need to dial it again to actually make the phone ring, I was doing a bit of research and it looks like PLAR will fix that but it seems to only work for one line.

 

Any help would be appreciated.
