[cisco-voip] enabling "ring down to 9" in existing dial-plan

[Lelio Fulgenzi]

We have a need to deploy some phones with an immediate ringdown to 9, so they don't have to dial 9 to get an outside line, i.e. for fax machines, pay terminals, etc. that are brought from an outside vendor temporarily on campus. For those that are permanently on campus, we will require them to program the appropriate off-net access code, i.e. 9. 

We are currently using the device/line approach, which means we give the device access to everything and use the line to prevent LD, etc. What I don't want to do is have to do a complete redesign or start building new filters, etc. 

What I had thought of doing was using a combination of partitions and search spaces and route patterns to mimic each pair of device/line classes of service I have, and then use translations to put in the 9. 

So, say I have: device-business-CSS (for the phone) & line-local-CSS (for the line). 
These each have device-business-PT (permit patterns) & line-local-PT (deny patterns). 


    • create ringdown-outbound-CSS and add device-business-PT and line-local-PT to it 
    • create ringdown-inbound-CSS and add ringdown-inbound-PT to it 
    • create RP: @ in ringdown-inbound-PT w / ringdown-outbound-CSS w/ 9 prefix 
    • assign ringdown-inbound-CSS to the analog device CSS and leave line CSS blank 

This should give me what I want, with minimal work.
