[cisco-voip] Call routing rules for AS5XXX connected to a PBX

[Robert Boyle]

Hello,

We use AS5XXX boxes as SIP<->PSTN gateways. Until now, everything has been 
fine and works ok. Now I have thrown a monkey wrench into the works. I am 
going to configure one port on one of our gateways to interface with our 
PBX. When a call comes in via PSTN, I want to route it to our SIP server, 
unless it matches a list of numbers should go directly to the PBX. When a 
call comes in via SIP, I want it to go out to the PSTN unless it is 
destined for the PBX, then it should go directly there. Is is possible with 
ACLs or dialer lists? Does anyone have a working example they wouldn't mind 
sharing? Thanks!

-Robert


This is what I think we should use on the "PRI" port to our PBX - any 
comments or suggestions?
