Hi again On Softphones and ATAs I can change the "Register Expiration" to a time that I determine. There is a way to change the value of 3CX extension status verification? 3CX check if the extension is available? I need to change that because sometimes there is a network crash or a incorrect Softphone close error (or kill with CTRL + ALT + DEL) and the extension is still green on 3CX management console. Thank You.
