Known Issue: SIP Domain Issue
Back to IM Compliance Main Page: Known Issues: IM Compliance
If you configure the SIP domain with upper case letters, for example Cisco.com instand of cisco.com, you may experience problems with instant messaging. This is a limitation of some versions of Cisco Unified Personal Communicator.
What Caused it?
Typically, this failure happens because the Cisco Unified Personal Communicator regards the IM as coming from a different entity for which availability information does not exist.
What Can You Do?
In Cisco Unified Presence Administration, change the proxy domain to lower case.
