Many thanks for the clarification - I do use both Macro() and Gosub() at present, and understand the difference ( I try to tell myself I do ;-) ). I do not use AEL dialplans. I had misunderstood the description on the changelog, and I had not noticed that it was an AEL change, rather than a generic dialplan change. There is clearly more of a difference between extensions.ael usage and extensions.conf usage than I realised. I can see now that AEL2 parses Macro (&) as a builtin, whereas extensions.conf will treat it as an application, and they have little in common.
