All,<br><br>I got a weird problem for Grand Stream 486 ATA registering on my ser server. Server in in US and ATA is registering from India. Here is ngrep trace. Every time the device tries to register the "Register" word get some extra characters. For example in this case REGISTER became <font size="2">R:50145EGISTER and ser replies with 404 User Not found. </font>
<br><br>Anyone faced this issue, any idea how to debug/fix this problem this. <br><pre><font size="4">U <a href="http://59.180.68.3:50145">59.180.68.3:50145</a> -> XXX.XXX.XXX.211:5060<br> <b>R:50145EGISTER</b> <a class="moz-txt-link-freetext" href="sip:XXX.XXX.XXX.211">sip:XXX.XXX.XXX.211</a> SIP/2.0..Via: SIP/2.0/UDP 59.180.68.3:50146;branch=z9hG4bKbd52be32ad52bf32..From: <a class="moz-txt-link-rfc2396E" href="sip:1004613554@XXX.XXX.XXX.211;user=phone"><sip:1004613554@XXX.XXX.XXX.211;user=phone></a>;ta<br>
