First successful voice calls

Hi all! Like I just wrot in my blog, I have managed to get the first voice calls between two MS on one BTS working. The Q.931 like call control never really was the problem, and paging as well as RR/MM seems to work very stable all the time. Bigger problems were related to the CHANNEL MODIFY that has to be done on the 04.08 level (for the MS side) as well as the 08.58 side for the BTS side - plus many classic programming mistakes in what used to be so-far untested/unused code. In any case, I have succesfully had voice calls through both the BS-11 as well as the ip.access nanoBTS. There are still lots of things left to be done (e.g. the E1 subslot assignments are still static, there is a big yet-to-be-explained lag on E1 based calls, Motorola phones seem to have compatibility issues, you can call yourself and make your own phone ring, etc). But at least the foundation is working.
