The local switch in the village. Each local village is totally autonomous in terms of supporting local calls. So the local freeswitch has to take care of this. (in reality, if there's no IP uplink, then there is no chargable call either, but never mind that, point is we don't have any centralised switch.) > If yes, then we'd need some SIP based signaling to switch > the (downlink) media plane [temporarily] back to the core. Yes, that would be the SIP re-INVITE. This is kind of what I was talking about before. in the freeswitch console, one can just type media_uuid + [uuid of the call] to switch the media in and out of bypass mode. FS then send an INVITE and SDP with the updated ip/port currently, osmo-sip-connector (and LCR + nitb and the fairwaves versions that are supposed to work but I could not get it to work), do not respond correctly and you end up with new call setup and chaos. > LCLS permits > for that, it's just that we have to implement those bits in OsmoMSC and > osmo-sip-connector. Right.. I hoped to gain something from the nitb stuff to port, but looks like not, so that would be a good part of this to table for getting done then. >
