<div dir="ltr">Sounds like a broken record but the mailing list is not the best place to report issues. Almost inevitably, questions will be asked and data will need to be collected like logs etc.
<div>This is why we already point to JIRA to file tickets.</div>
<div><br>
</div>
<div>Recommendations: </div>
<div><br>
</div>
<div>1) Make sure you don't have "answer_delay" set.</div>
<div>2) Check the media signaling data to make sure you are not using "rtp-auto-adjust which adds a time to media establishment to correct for incorrect media IPs.</div>
<div>3) Get a pcap as well as debug + sip trace before reporting any issue because its always going to be the first request anyway.</div>
<div>4) Use JIRA, feel free to ask about the JIRA here but don't rely on 1990's listserv server to track the issue progress.</div>

Correction, we had moved FreeSWITCH 1.4 (not 1.8) to Server 1 which worked without any audio delays. Upon testing FreeSWITCH 1.8 on Server 1 there is a 1-2 second delay before RTP is established once the call is answered.
<div><br>
</div>
<div>This is a FreeSWITCH 1.8.2 issue, not a Debian 9 specific (also occurs on Debian 8). FreeSWITCH 1.6 and 1.4 are not effected using the same configuration through-out.</div>

We have built two test servers side by side on the same hardware with the same configuration, as follows.
<div>Server 1: Debian 8 with FreeSWITCH 1.6.20</div>
<div>Server 2: Debian 9 with FreeSWITCH 1.8.2</div>
<div><br>
</div>
<div>We can replicate the 1-2 second delay on Server 2 only, whereas Server 1 provides near instant RTP in both directions upon answer. Interestingly, if we move FreeSWITCH 1.8.2 from Server 2 to Server 1 there are still no issues with delay on Server 1, the
problem is only observable on the Server 2 running Debian 9 so the problem is not specifically related to FreeSWITCH 1.8.2.</div>

<div>At this stage it seems likely the issue lies with Debian 9 or the change in packages on Debian 9.</div>
