We're thinking about bringing one or two USRPs configured to run OpenBTS. We'll be interested in testing the setup in real life and interconnecting them with your OpenBSC setup - I think it should be possible with Asterisk.
I don't think we have a particular interest in interconnecting those two, as our resources are typically _extremely_ stressed, and we would rather not reconfigure the installation while it is running. It will already be very hard to do what we currently have on the agenda. I don't really see what would be gained from routing voice data over voip between OpenBTS and OpenBSC.
What would be an interesting project is to reuse the OpenBTS transceiver code (but not the layer3 protocol stack + sip gateway) and add a BTS-side A-bis implementation, turning OpenBTS into a real BTS that can connect to OpenBSC through A-bis. If there's anyone volunteering to get that work started, I'd be willing to experiment with it at 26C3. But that also not on the actual production/live setup, but on a second OpenBSC instance.
We see this from different points of view. :) We're interested to show possible ways of OpenBTS interoperability with more conventional BTSes like ones OpenBSC use and evaluate problems which will arise there. But we want to show this with "flat IP" network instead of burdening OpenBTS with A-bis interface. I believe in the positive impact of OpenBTS and OpenBSC interoperability for the both communities and as encouraging factor for possible future OpenBTS test sites.
We're ready to work with you beforehand to minimize on-site efforts.
PS Where can we find agenda? Official 26C3 site is nearly empty.
