Cisco Unified Mobility requires our Cisco Unified Communications Managers to be on version 7.1 or above, and we started deploying the service soon after we’d upgraded to 7.1. We deployed Cisco Unified Mobility in each of our 13 Cisco Unified Communications Manager clusters, rolling out the service on a site-by-site basis. This gradual transition process helped to smooth the impact of supporting users and the potential for spikes in outbound calls as employees began working with the SNR feature. At first, we worried that a large number of calls going out to mobile phones from Cisco sites might overwhelm smaller outbound trunks, but so far we haven’t seen any problems there. Also, our gradual site-based rollout made it easy to avoid countries that do not allow outbound calling from our private VoIP network to the PSTN (primarily in the Middle East, and in India).
