Why each option
Cisco Unified IM and Presence is built on the open XMPP standard, can be deployed from the Cisco cloud while retaining local call control, and supports iOS and Android mobile devices.
IM and Presence is deployed as a separate server node added to the CUCM cluster, not simply toggled on via a 'Services' menu within the CUCM administration interface.
Cisco Unified IM and Presence is based on XMPP (Extensible Messaging and Presence Protocol), an open IETF standard (RFC 6120), which it uses for instant messaging and presence federation.
XMPP is an open, IETF-standardized protocol (RFC 6120), not a Cisco proprietary protocol; it was originally developed by the open-source Jabber community.
Cisco supports a cloud-hosted IM and Presence deployment (via Webex/Cisco cloud) that can still integrate with an on-premises CUCM cluster for call control.
The Cisco Jabber client, which connects to IM and Presence, is fully supported on both Apple iOS and Google Android mobile platforms.
Remote access (VPN-less external connectivity) is provided by Cisco Expressway, not by the IM and Presence Service, which delivers chat and presence but not remote access itself.
