We recently switched from Citrix VPN to Global Connect for remote users. Since this has taken place, we have had users of both applications will randomly experience where they cannot answer a call. The call makes it appearance, they click on answer, however it is ignored. Eventually when the call is either redirected (RONA) or to voicemail, the application will respond with 'unable to accept call session'. Then the application will re-register and work fine for some random amount of time. When we ask the users to go back to the original VPN application, all is well again. In the Wireshark trace on a failed call there is a ARP request followed by a port 443 request from an very unexpected IP address.
