We are using freeswitch to transcode between opus and g711. We have rtp-timer-name set to none in sip_profiles. If we experience packet loss on the inbound leg (opus), freeswitch will take no action. When the next opus packet arrives, freeswitch sends a pcmu rtp packet with continuous sequence number and timestamp to the outbound leg. That is, there is no way to tell from the outbound leg that there was a packet loss on the inbound leg.

I would prefer the following behavior:

1. When there is a packet loss on the inbound leg, increase the sequence number and timestamp on the outbound leg.

2. When there is a packet loss on the inbound leg, interpolate the missing packet using opus plc. This only works for a few consecutive lost packets and not for burst loss.

Is there any config parameters to force either of the above behavior?
