hi, i have a phone that requests a SDCCH channel after it is paged. (even if paging request required a TCH Full channel.) in this case, i assign a GSM_LCHAN_TCF_F channel except for location update. (see patch) in the second part of this patch, i check if the current channel is a traffic channel. if not, we can't use it on calls BSS->MS. this happens if a call is received after location update, but before the channel is released. this second part depends on the application patch (36). andreas
