In operational networks, it is perfectly fine to let

of MS capabilities and network-policy order of preference decide which

be able to manually select a specific codec for that specific call. I
can think of two ways:
As I already mentioned, the existing silent-call command is a bit
special in a way that it allows to select a specific TCH rate (full or
half) and a specific codec (if needed). The test-call command I
proposed can by implemented on top of the existing silent-call logic.
Just to clarify: currently when you invoke the silent-call command, no
Call Control signalling is happening at all. Only paging and then the
RR Assignment procedure. Strictly speaking it's not really a "call",
just a channel assignment without any further commands.
