<p>Hi,</p>
<p>Got a problem with a handset that doesn't seem to be registering
on our Freeswitch server. The diagnostics from a member of Cisco
support said...</p>
<p>"<span class="mediumtext">At packet 422 we see the phone
<a class="moz-txt-link-rfc2396E" href="mailto:0_4147057716@192.168.40.26">"0_4147057716@192.168.40.26"</a> send a registration request to
5.9.36.113:5060 from 175.159.77.82:32060 - We do not see a reply
to this from the SIP provider.<br>

We responses to requests from <a
href="mailto:0_359240637@192.168.40.26">0_359240637@192.168.40.26</a>
with source port 5060, which suggests to me that the SIP
provider is not replying to the high UDP port requests. As the
MX is a NAT device, subsequent SIP requests will always have a
high UDP port."</span></p>
<p><span class="mediumtext">I'm not sure where we might configure
acceptable ranges of SIP source or if it's something else.</span></p>
<p><span class="mediumtext">Thanks for any suggestions...</span></p>
