hi,
just had problems with jitter of RTP via wireless lan. changing size of
jitter buffer did not solve the problems, packets got dropped. this
patch allows to disables the jitter buffer, if a jitter value of 0 is given.
regards,
andreas

Dear Andreas,
do you happen to have a PCAP file of the stream arriving at the BTS? I
had a lot of issues with FreeSWITCH and their jitter buffer and as a
minimum I would like to at least have the right inspection/logging to
detect/analyze these issues.

hi holger,
i traced data between openbsc and osmo-bts. i put a sequence number in
the payload to see, if packets get dropped. i could see that the
wireshark actually showed the missing frames. also i put debug into
libortp to see if they arrive there, they do! the jitter algorithm just
dropped them. for my case (lcr) i did a 30 minutes call today using
osmo-bts (calypso-bts) and openbsc-lcr. it worked best, without any
raising delay. i think that my setup (slow netbook, many processes) does
not get well with jitter buffer of libortp.
regards,
andreas
