Maybe one of the developers can confirm this risk of > working with macros ? I don't think you need an Asterisk developer to tell you the risks of using macros in deeply nested situations. Quoting the documentation of Macro: "Because of the way Macro is implemented (it executes the priorities contained within it via sub-engine), and a fixed per-thread memory stack allowance, macros are limited to 7 levels of nesting (macro calling macro calling macro, etc.); It may be possible that stack-intensive applications in deeply nested macros could cause asterisk to crash earlier than this limit. It is advised that if you need to deeply nest macro calls, that you use the Gosub application (now allows arguments like a Macro) with explict Return() calls instead." > I'm now also moving towards GoSub where possible.
