<DIV><FONT face=Arial color=#000080 size=2>Symptom: Phone after about 15mins
will stop functioning </FONT></DIV>
<DIV><FONT color=#000080>Problem: DHCP lease renewed but default route
dropped</FONT></DIV>
<DIV><FONT face=Arial color=#000080 size=2>Fix: Assign a static ip and problem
is resolved. Upgrade to new firmware once it is
released</FONT></DIV></FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>It turn's out that these phones have a few
issue in <FONT color=#000080>1.0.3.81 firmware. The phone may stop
transmitting packets if configured with DHCP, if DHCP is being provided by
certain devices. Netopia routers have been confirmed in this category. It
turns out that there is some differences btw the implementation of DHCP btw
different vendor and this is causing the phone to loose it default route and
stop transmitting packets approx 15mins after the phone receives it's lease
after reboot. GrandStream says this will be fixed in the next
release.</FONT></FONT></DIV>

<DIV><FONT face=Arial color=#000080 size=2>Stun and Budgetone: I have observed
odd behavior with the phone and various STUN server's. Leaving the phone
behind a given router and pointing the phone's stun server at
various versions of STUNd reporting different results to the phone. I
am not sure if this is a budgetone or stun server problem. but I do know
that it causes problems it certain environments.</FONT></DIV>
