(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.)
We do play back "You're credit is about
to expire" messages.
We would have to switch the stream back to do that.
Who takes those kinds of
decisions? the central switch in the
datacenter? 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.
