That refers to dialplan extensions, not user extensions. Yes there is confusion there in terminology since there are two very different types of extension - dialplan vs registration.

Transfer and execute_extension can also be used to execute another extension, but there are differences in how that's done which means each solves different use-cases.

You get a full outgoing and incoming channel where FS calls out and back into itself. The new incoming channel is then handled just like any other call. That's where the evilness comes in... it uses a lot more resources than might be needed by other approaches, and every channel gets its own CDR so that can screw up your CDR/billing system unless you handle it correctly.

Once the call is bridged FS can unroll the loops to simplify the call handling and resources consumed.
