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
