inter-BSC handover

Hi all. I'm testing to see if inter-BSC handover will work between RBS and osmo-bts, given that support for handover from an E1 to RTP call is not yet supported. Among all kinds of other things going on, I'm not finding it easy to understand how to configure everything for inter bsc handover. I know there are two videos (at least) from Neels at OsmoDevCon, on the subject of handover and then inter-MSC handover. I have one DUG/RUS configurarion with the e1d, bsc/msc/mgw/hlr running on the associated PC and one remote SysmoBTS, which is running osmo-bsc and it's associated MGW locally. All that is fine, I can call between the two BTSs successfully. I'm guessing I should add the neighbours manually in each bsc but I'm not sure what to configure in the MSC. Maybe I'll figure it out this evening, but I thought it best to also write most given the time zones and most of you guys will see this before I get back to work tomorrow. Thanks! k
