[Gergely Dömsödi (JIRA)]

     [ https://issues.asterisk.org/jira/browse/ASTERISK-25332?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Gergely Dömsödi updated ASTERISK-25332:
---------------------------------------

    Attachment: out.pcap
                in.pcap

Incoming and outgoing leg of a call which shows the issue. On the incoming stream RTP the marker bit is set properly when the audio is restarted, on the outgoing stream, generated by Asterisk, it is not set.

> 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.
