If the BTS automatically detects the RTP format upon
rx, why cannot we simply detect it automaticall […]
1: The MGW does exactly that but
it has no knowledge about when to convert and when not. It just converts one format into
the other and vice versa. It works fine for homogenic setups but once you add a BTS that
uses the other format it won't work.
2: in MGCP/SDP There is no specified way to signal which HR GSM format to use and it would
also address the problem at the wrong location. The BTS should transit in the expected
format and we shouldn't be forced to convert it at some second-tier point.
We can solve the problem via osmo-bts.cfg. I personally would prefer that solution since
it is much simpler, but I thought we would prefer to have the BTS parameters configured by
the BSC.
