Hi. We're using the 3CX Phone version 6 with our call center dialer solution. The problem is that the 3CX stop working after some calls, returning a Windows error. After the crash we have to run the Windows task manager, kill the 3CX process and start the 3CX Phone again. That problem occurs only when we run the dialer. Normal call operations runs OK. We're using Windows XP SP3, 3CX Phone V6 and Asterisk. The pause between the calls arround the 15 seconds. [EDIT] The problem doesn't occours when the option "Auto-ans" is enabled. If we set "Available" option the 3CX stops working afters 3 or 4 calls. Regards, Renan.
