<span style="font-family:Calibri, Arial, Helvetica, sans-serif;font-size:11pt;color:black">This seems normall But tftp time is tied directly to latency delay as every packet is acked, and 512k max packet size.
<br>
<br>
Peer firmware sharing and load server could help.<br>
<br>
What exact version 8x to 9x?<br>
<br>
Hopefully the switch to https or is around the corner. Tftp is great with small files but not large phone loads. The VIP12/30 had smaller loads.<br>

<p class="MsoNormal">Hey guys,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are gradually upgrading our fleet of 7965G's to SCCP v9 software from v8.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We have found an issue at remote sites (higher latency) where phones (with any 9.x firmware) are taking upward of 10-20 minutes to register! This delay seems to only occur when a full power off / power on occurs.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Downgrade the phones back to v8.x and whola! No problem.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">We are going to try and simulate this in the lab with a WAN sim and then probably get TAC involved. I suspect it has something to do with the extra latency involved but as mentioned we have had no trouble with v8.x software.
<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Has anyone come across this problem? It seems a bit oddball I know.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Any hints or suggestions are most welcome.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks,<o:p></o:p></p>
