Gergely Dömsödi commented on ASTERISK-25332:
--------------------------------------------

The same issue was present in older asterisks with chan_sip (tested with 11.18.0), and it is also in 13.4.0 with which this log was made.

> When asterisk receives an incoming call from a peer capable of VAD (rtp packets stop coming on silence, and start coming again on voice), in the outgoing leg of the call, the marker bit is not set on the first packet when the audio is restarted, so the called party is unable to play/sync audio properly.
