T38 CTI with 3CX
We recently upgraded a large install of about 70 T38 phones with 3CX from version 11 to V12. The new 3CX Windows Phone is not activating CTI on the phones. We updated the phones to the most current 3CX supported firmware ( When we try to use CTI the softphone does nothing and the phone also does nothing. However, if we change the "Trusted Action URI Server List" from "any" to the IP address of the desktop computer the phone will prompt for control, but if we reboot the phone or re-provision the phone it will no longer function and will not prompt for control. We have our provisioning file set for "any" under the "features.action_uri_limit_ip = " setting.

We have a couple of questions about this issue:

1. CTI will not function with “any” defined in the URL field.
2. Is there a timeout for the phone confirmation for control?
3. If the confirmation is missed will it come back?
4. Will the confirmation need to be done every time the phone is rebooted, re-provisioned, or firmware updates?

On a different note, is it possible to turn off the audible stutter tone when a new voicemail message is left?

Thank you in advance for your assistance.
