Neels Hofmeyr nhofmeyr at sysmocom.deI've been asked about IuUP specs. So far I know of 3GPP TS 25.414, 5.1.3.3.2 RTP Payload: "A single Iu UP PDU, as described in TS 25.415 [24], shall be transported as RTP payload." And 25.415 contains the juicy bits. We have osmo-mgw branch neels/iuup refactoring some RTP packet handling to be able to easily strip/insert an IuUP header with correct checksums etc., and we have libosmocore branch laforge/iu_up implementing a state machine about unshuffling the payload bits. I guess to get a working solution we would need to marry those two branches and fix whatever is still broken/not implemented in there. They are still potentially wildly incompatible. ~N -------------- next part -------------- A non-text attachment was scrubbed...
