I recently upgraded my Cisco call manager so I could leverage the Cisco jabber client. Once installed and configured on my LAN it was flawless. We are just using the soft phone feature on iPhone . After installing the Cisco any connect mobile VPN client I was able to connect The jabber client to my call manager. I can place a call when the other party picks up the line goes silent. I hear a ring and then nothing.
Call manger is 7.1.5 ( the last 7 versions not 100% sure)
