Subject: Re: [OSL | CCIE_Voice] Device Mobility with Local Route Groups

Hi Jeff,

You are right, phones at the roaming location will get the LRG configuration 
from the roaming DP, we cannot avoid this.

However, a workaround to your scenario may be to implement + dialing, in which 
you globalize the caller input (translation patterns) depending on his/her 
dialing habits and localize it for the outgoing gateway (cd xform patterns), in 
that way, a US user roaming to UK will be allowed to use the LRG route patterns 
(using US dialing habits) therefore using local UK resources. The drawback here 
is that this won't be a cost effective solution, in which case you will have to 
implement teho/location specific route patterns to route calls out and save 
costs,

Hope this make sense,

Having trouble understanding how this is supposed to function without Site 
Specific Route Patterns and Route List/Group.  If  using only non-site specific 
route patterns pointed to local route group I see no value in this. Of course I 
am probably mistaken...hence this message.  Scenario below


No location specific Route Patterns exist...all route patterns point to local 
route group.

Device roams from HQ to BR1  DMG is US for both. (CSS for both home and Roaming 
device pool is CSS-LD). Roaming sensitive settings are applied  as well as 
Mobility Settings.    which means device will use local route group defined in 
BRI device pool for all calls based on CSS-LD.  User dials 95551212..No problem 
here since calls will now be sent out BR1-GW as expected with correct digits 
assuming predot is applied via Called Transformation.

However take the same scenario above except the DMG is now changed to UK for 
roaming phone.  Mobility settings are no longer applied meaning CSS does not 
change. The purpose for this is supposed to be that user does not want to have 
to dial differently when in a new country. However Local Route Group is still 
obtained from roaming Device Pool. Since all Route Patterns point to local 
route group and local route group is now UK.... ALL calls will now be directed 
to UK gw.  Call will fail as  digits PSTN is expecting will be incorrect.

What is the excepted way to get calls to NOT route out local gateway but 
traverse the WAN and go out US gateway.  I can't think of how to do this 
without using location specific Route Patterns and Route Lists which now 
defeats the purpose of the Local Route Group concept.  ARRRGGGGH
