We are using personal communicator in our organization for end users desktop & Laptops! When they dial outside (any mobile) number from personal communicator, then the mobile ring and two way communication established, but when the same users use their laptop from home via VPN and use the personal communicator, when they dial out side mobile numbers, only one way communication is established. On the same laptop if they use (IP communicator) then no issue, they dial out side mobile,land line and two way communication gets established. I know that IP Communicator uses SCCP & Personal Communicator uses SIP to get registered with the Call Manager 6.1.
Any help regarding the above issue would be really appreciated
