I am using Extension Mobility with IP Communicator and am experiencing no known issues except for when agents try to work remotely through VPN. At which point, when they click on the service and enter their user name and pin, they receive an error, "10." and are unable to sign onto extension mobility. I can statically assign their IP Communicator with their profile and they can then work through VPN. To the best of my knowledge, I am not blocking any traffic once authenticated through VPN.
Any assistance with this issue would be greatly appreciated!
BTW: Call Manager 4.1.3 sr4d and IP communicator ver 220.127.116.11
