[cisco-voip] Device Mobility and CSS question

[Heim, Dennis]

One thing to note with device mobility is that the callmanager group is not impacted by device mobility last time I checked. If you are trying to load balance where your phones are registered you would need to have separate device pools that are configured on the phone.

I normally do this via Global-1-DP & Global-2-DP, which have different callmanager groups applied to each in order to balance which server my phones are registered to. That 2 device pools are applied to the phones and the rest of the settings are propagated via  device mobility/device pool roaming sensitive settings.

Teressa,

When you add multiple Device Pools to a DM Info, they are load balanced (one then the other).  I'd suggest breaking up the subnets to one per agency if possible if you want the Device CSS to be assigned dynamically.

When you are using Device Mobility where does the user profile get its Device Pool assignment?
Here is the problem we are trying to fix.  We want to use a combo of line CSS and phone CSS where the line CSS takes precedence.  However, we are using Device Mobility too.  So the line CSS is easy to assign.  But we can't figure out how the user's device profile would get assigned a CSS (it seems that the CSS would be there in lieu of having a static phone to assign it to).  It appears that the equivalent of a "phone CSS" when using Device Mobility would be whatever the Device Pool sets, and the Device Pool is set from the Device Mobility Info.  Here is the further issue, we have many small agencies in one building.  They each should have their own CSS, but there is one subnet per floor in the building.  This means we have one DM Info per floor, and thus one Device Pool, but we need to set multiple DPs.  I see that you can add multiple Device Pools to a DM Info entry, but how would we make sure the mobility users get the right Device Pool?

We are on CUCM v. 8.6.2.

We're at the tip of a huge deployment and would like to get this set up correctly.  Thanks for any help you can give.
