Harald Welte gerrit-no-reply at lists.osmocom.orgHarald Welte has submitted this change and it was merged. Change subject: new_rab_par_voice(): add bitrate params, call with (6700, 12200) ...................................................................... new_rab_par_voice(): add bitrate params, call with (6700, 12200) The guaranteedBitrate lowers from 12200 to 6700, which is mimicking the values found in a trace from a production 3G environment. So far we have no reason to choose these values other than knowing that other operators seem to do this. This came up while trying to fix voice RAB for the nano3G, but this patch had no effect on that. Now that it's here, we might as well keep it.
