[Asterisk-Users] AEL #include

[Douglas Garstang]

Oh Crud. So, if I want to jump to another extension or context, I have to specify the full context, extension and priority? I can't specify a label? It's a bit tricky trying to jump to a specific priority in an extension when they're all called 'n' !

Why is something so simple such a mess...
