In a correctly configured setup we should always see
the same format in both directions.
If you say so... I don't think that's really stated anywhere in the spec, and
sounds like a personal expectancy of what a "correctly configured setup" is imho
😊
I thought the OML feature flags were introduced for
things like this
Yes, to know that a BTS supports a given feature. Not to indicate which of the several
supported is to be used.
BTS model is a PHY based model with TS 101318 support
or an osmo-trx based model with RFC 5993 support.
So our osmo-bts-sysmo is transmitting different RTP type than our osmo-bts-trx? what a
mess! 😮
The BSC knows that it talks to an osmo-bts, but it
does not know if this BTS model
My point is only that you still need to store that in osmo-bsc hardcoded somehow for other
types of BTS, like nanobts, etc. so you could simply do the same for osmobts (you will
need this for older versions of osmo-bts anyway). Maybe that's actually done using
this set of features?

Extending IPACC can be also a way, here we can at
least be sure that osmo-bts type BTSs will support the extension but we will have to make
sure that older osmo-bts versions will tolerate/ignore the extensions.
Yes, have a look if adding the new IE is really a problem for old versions (I think it
won't be an issue). If it was, then you could add a new BTS feature stating whether
the BTS supports this new IE and then only send it based on it.
