We do not have the CER software. We may not get it until next year. We have users with IP Communicator and a few other users with the 7920 phones. When they travel from one office to another, their calls will still go out to the PSTN as if they were in their home office. What is recommended in regards to 911 dialing? If they were to dial 911 from the softphone or wireless phone while visiting another office, their calls would not be routed out the proper door. We are concerned about the safety of employees and the legal ramifications of this problem. What can be done if CER is not in place? Any recommended best practices in this situation?
