Overview 

The UCC Mobility Service is comprised of the Single Number Reach and Dial-IN Access 
applications. Each o these mobility applications use ephones to answer the incoming call and make 
the outgoing calls. These ephones have to be provisioned in the CME and then configured for the 
Mobility Service using the UCC Server Wizard. The ephones provisioned in the CME for use by the 
mobility applications are referred in this document as the mobility-ephones.  

1.  The mobility-ephones can be provisioned for two different types of usage – mobility-

ephones that can be used to process any user’s mobility service requirements and 
dedicated mobility-ephones which can only process one specific user’s mobility service 
requirements. The dedicated mobility-ephones typically have a shared appearance DN of 
the user’s primary DN. 

2.  Mobility application use ephones from the router with the call-terminating ephone. In 

multiple router configurations, the number of mobility-ephones required on each router is 
dependent on the number of mobility sessions originated on behalf of users on that router. 

3.  For incoming calls to the Dial-In Access features, the mobility-ephones are used from the 

router that received the PSTN call. 

4.  Mobility-ephones are grouped into pools using the Server Wizard. Such pools can be 

shared among multiple mobility applications or they can be ‘dedicated’ to a single mobility 
application. 

5.  The mobility applications acquire the needed ephones form the pools and return them back 

to the pool. 

6.  If there are multiple pools associated with the application, ephones are acquired first from 

the dedicated pools, if none are available then from the shared pools. 

7.  The mobility applications use one ephone for the duration on the session with the following 

exceptions: 

a.  One additional ephone is used when setting up a new call. For example if the SNR 

is making two simultaneous reach out calls, then two additional ephones are used, 
one for each call. Once the reach out call is processed when either the user 
answers or on timeout, the call is terminated and the ephones are returned to the 
pool. These ephones will typically be in use for less than a minute. 

b.  If Mid-Call features are enabled, then the SNR session continues for the duration 

of the call. If Mid-Call features are disabled then all ephones for the SNR session 
are freed up once the SNR connection is made or the call is sent to voice mail.
