congratulations! Thanks for your effort.
I'm doing without osmo-bsc_mgcp at all: after a chanel is being opened, my transcoder just replies the first rtp from bts and keeps this address as endpoint.
Do you already have a plan for dealing with intra-bsc hand-over in this case? The advantage of having different RTP IP/Port on the A and the A-bis side is that the BTS can change due to intra-BTS or intra-BSC hand-over, while on the A interface everything remains stable/unchanged.
- in my case, OpenBSC makes BTS to talk to a predictable port at transcoder
See my comment above. I'm not sure if this is the best solution moving forward...
- I could not guess your reasons (as well as ways) to configure voice
codecs within BSC, and hardcoded them within bssap_handleassingm_req()
I'll let holger comment on that. My guess is that the MSC that was used didn't have enough flexibility in configuring the codecs so we override it in the BSC.
Hope to prepare a proper letter it in about a week
Looking forard to it!
