Hi
Due to Covid 19 we had a number of customers rapidly switch to 3CX due to the ease of using a mobile app. Now they are returning to the office, we had the issue of them wanting to retain the mobile app but not have to replace the Alcatel desk phones.
After some messing around and an unusual way of solving CLI issues, I thought I would let people know that this can be achieved. There isn't any other feature transparency but CLI to show extension to extension numbering and both inbound and outbound CLI is possible.
