In operational networks, it is perfectly fine to let the combination of MS capabilities and network-policy order of preference decide which codec will be used - but for test calls, it would certainly be nice to 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.
