User looses Sametime Unified Telephony phone icons, when you log into two clients with the same user account, from the same machine (same IP address)
Client 1 that you log on with works perfectly fine (Sametime Unified Telephony will work) but when you log on with a Client 2 with the same username and password you will notice that you will loose Telephony awareness in the first client.
Logging into Sametime Connect Client or Lotus Notes (Sametime Embedded) Client on the same machine with the same user credentials causes problems when the clients register with the community server for Telephony awareness

Resolving the problem
It is not supported to log into two Sametime Connect Client or Lotus Notes (Sametime Embedded) Client with the same user credentials and expect Sametime Unified Telephony to work correctly.
