<p>No problem and thanks for looking into this. The debug logs can be found here. The IP addresses and hostnames are anonymised (as required by my client). In this scenario, traffic should go to <code>185.10.20.29</code> first, and failover to <code>185.10.20.30</code> or <code>185.10.20.31</code> based on DNS SRV.</p>
<p>What I was seeing with tcpdump:</p>
<pre><code>1: 185.0.1.34 => udp:185.10.20.29:5060
2: 10.0.1.14 => udp:185.10.20.30:5060
3: 10.0.1.14 => udp:185.10.20.31:5060
</code></pre>
