Well, you are asking the lcr author to implement something for yate.  I
think it may be a bit of a strange question ;)

I would be honestly surprised if yate implemented connection-oriented
SCCP procedures.  This is only used on the GSM A interface and not to be
mistaken with the datagram-oriented SCCP (UDT only) used by TCAP/MAP.

In fact, it might make more sense to use the existing libosmo-sccp and
	either
1) add SCCP-lite (IPA multiplex) support to yate
	or
2) implement M3UA as a transport for osmo-bsc's existing libosmo-sccp
   and use that to connect to yate.

But then, I am not aware of any commercial OpenBSC user who has any
interest in OpenBSC with classic A interface.  Everybody wants to move
away from TDM and to an all-IP RAN.

Furthermore, at least as far as I know, yate may not support AMR/EFR
codecs, which makes it somewhat limited in the context of GSM.  I may be
wrong here, though.

Regards,
	Harald
