[cisco-voip] problem with part and css

[Lelio Fulgenzi]

Think of it this way, a calling search space is simply an ordered list of partitions which the line or device searches through for a match of the dialed digits. If you look through the traces, you will see the term PSS which I believe stands for Phone Search Space. This is made up of the line's ordered list of partitions and then the device's ordered list of partitions. For example:

CSS1=PartA,PartB,PartC
CSS2=PartX,PartY,PartZ
Device assigned CSS1
Line assigned CSS2
the PSS would be: PartX,PartY,PartZ,PartA,PartB,PartC

So the idea you propose is a valid one. We use it here. Assign the device access to everything and then deny the line access to particular services. We isolate the 'everything' to PSTN access and actually allow oncampus access through the line's partition.

You have to make sure that the denies are at least as specific as the allows. And by denies, I mean, creating a route pattern that has the 'block' option checked.

Post back if you need more...

  we have a cm 4.1.2 es 41   
  i was just told by a tac rep that 4.1. and higher uses both css on line and device.
  what does this mean????

  i have my device as unrestricted and all of the part in it.  and then i have my line configure with a customize css, ie maybe no int calls or LD calls.  
  the problem im having is that when i make a ld or int call,  uses the device.  and when i make a ipphone call ( 4 dgit dialing between sites) it uses the line. I dont understand this.  nore do i understand  the statement   IT USES BOTH LINE AND DEVICE.   can someone Please clear this up for me.  Thanks in advance
