We have Version 4 of My CallPilot installed. We did have Version 5 installed...however with Version 5 we were getting all kinds of issues with our CallPilot Servers. It looks as though both versions login to the CallPilot Servers every minute...so I'm afraid that the Vertiual Memory Errors and other issues with return with Version 4. Anybody had any luck with My CallPilot in a mainly Version 4 of CallPilot Server environment? All our CP Severs are 4 except for 1 which is 5. Thank you...Bryan.
