Yes, my bad. Misinterpretation of Wireshark graph:

Something definitely changes when the media bug is added. I will work out what but I think FS is inserting silence frames when the media bug is on, and not inserting them when it is off.

Thanks for setting me straight.

I'm not talking about the new stream for the eavesdrop. I'm talking about the streams on the A and B legs of the bridge. 

I don't see why FS would rewrite sequence numbers on an RTP stream which it is simply bridging (no transcoding, no muxing, etc). Sequence numbers allow packet loss to be detected and compensated for. If FS is not running a JB or PLC then it should leave discontinuous sequence numbers as is so that a downstream JB / PLC can use them.

I'll send some Wireshark screenshots shortly. And will double check re seq num vs timestamps.

Seq numbers are always rewritten.  Maybe you mean timestamps?

The muxing and recreation of a new media stream requires a newly generated stream.  There is not a way around that.

Hi guys

Seems than running eavesdrop (and potentially other media bugs) on a bridged channel results in the rewriting of sequence numbers on RTP streams, potentially hiding packet loss when it occurs and creating havoc with downstream jitterbuffers.

Is there a way to disable this behaviour?
