I have a couple of hundred entries in the Dial Plan and have to make frequent edits. There is no sort order in the grid so it takes ages to find anything. Can you add a search function or at least the ability to sort by columns?
Sorry but there is no way to sort columns in the Dial Plan. By default they are sorted by the priority with highest priority at the top. This allows you to see what rules are first. It is a top down processing when applying a dial plan to the DNIS.
You can add a feature request here if you want to submit that:
