Someone had showed me a new approach last month or so about devising a new strategy for CSS and PTs for enterprise deployments. It was a Cisco document about the recommended approach for Line CSS/PT and Device CSS etc.
You can basically have a couple different approaches. Example:
30 sites
- each site has it's own PT/CSS (island)
- 4 digit extensions
- 3 digit site code
- Translation patterns to/from each "island" (granted, alot of Translations, but less processing used on CUCM if all lines are in the same CSS)
- Unity 7 digit mailboxes
But I saw some document that create a new approach or something that was different.
Anyeone seen this or have other recommendations?
