We currently have a unity server using version 4.2, VM can be picked up OK internally, but if you try calling in from the PSTN/Mobile -
enter user id #
enter pass code #
You receive the following message - "This system is temporarily unable to complete your call"
I looked around and l see that the above message takes you into the fail safe mode of Unity. Do l need to configure something in Unity to get this resolved?
Any help much appreciated.
