  1. POAzure VM can't receive incoming SIP request
    text
    copied!<p>I am trying to run my SIP client on Azure VM for the first time. I have added endpoints to the VM to allow SIP traffic (UDP 5060). I have disabled the windows firewall on the Win2012 R2 VM. Even the ACL is set to 0.0.0.0/0 in the VM endpoints settings.</p> <p>When I send a SIP INVITE from Internet, I can see the INVITE on wireshark, but it never reaches the SIP client. I even tried eyeBeam client instead of my SIP application, same result. Wireshark can see the INVITE SIP packet, but it never reaches the application.</p> <p>Since wireshark can see the SIP packet, my Azure settings may be OK. But who is stopping the packets from reaching the SIP client?</p> <p>I tried tracert from the VM, it returns a blank, to any public IP. For example:</p> <pre><code>tracert www.microsoft.com Tracing route to lb1.www.ms.akadns.net [134.170.188.84] over a maximum of 30 hops: 1 * * * Request timed out. 2 * * * Request timed out. 3 * * * Request timed out. 4 * * * Request timed out. 5 * * * Request timed out. 6 * * * Request timed out. 7 * * * Request timed out. 8 * * * Request timed out. 9 * * * Request timed out. 10 * * * Request timed out. 11 * * * Request timed out. 12 * * * Request timed out. 13 * * * Request timed out. 14 * * * Request timed out. 15 * * * Request timed out. 16 * * * Request timed out. 17 * * * Request timed out. 18 * * * Request timed out. 19 * * * Request timed out. 20 * * * Request timed out. 21 * * * Request timed out. 22 * * * Request timed out. 23 * * * Request timed out. 24 * * * Request timed out. 25 * * * Request timed out. 26 * * * Request timed out. 27 * * * Request timed out. 28 * * * Request timed out. 29 * * * Request timed out. 30 * * * Request timed out. </code></pre>
