Hi Christian, I've had a quick look over this report (and we also spoke on IRC a little while back), but sadly it's beyond my level of experience. Realistically a ticket is usually picked up by either someone who has an interest in the subject, or by a core developer based on priority. So there are three viable options here; a) Keep trying to fix the problem, mess around with the config, perhaps see if you can reproduce it in a clean room environment, i.e. in virtual machines b) Try and bait the core developers to take a look (you can try the 5-for-1 approach mentioned in [1], or post a bounty [2]) c) See if anyone picks this up Sorry I couldn't be of any further assistance on this one :/ Cal [1] http://lists.freeswitch.org/pipermail/freeswitch-users/2013-June/096500.html [2] http://wiki.freeswitch.org/wiki/Bounty On Thu, Jun 20, 2013 at 9:07 AM, Christian Tari <ctpi.list@gmail.com> wrote:
Hi,
Im having problems with jitterbuffer when transcoding from GSM to PCMa. On the incoming (GSM) side we have mobile devices using 3G network and generating jitter and packet loss. If a packet arrives late or lost, it gets replaced by a high pitch noise on the output (PCMa) stream.
I've tested with other codecs (pcmu,opus) on A leg which worked fine.
Settings in dialplan: <action application="set" data="rtp_jitter_buffer_during_bridge=true"/> <action application="set" data="jitterbuffer_msec=200:200:160"/>
Log,trace,audio are in ticket #5511<http://jira.freeswitch.org/browse/FS-5511>
Could you give me some hints how to make it work?
Thanks in advance, Christian
