had a lot of issues with FreeSWITCH and their jitter buffer and as a

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
