<DIV><FONT size=2 face=Arial>My apologies in advance for sending this to the
Cisco VOIP list, since it's not, strictly speaking, a cisco issue, but I'm
hoping to find someone here who has worked with NEC DT700 voip phones, because
we are trying to get an answer to what should be a simple question, but no
amount of calling to NEC has yielded an answer, and multiple searches online
have proven useless.</FONT></DIV>
<DIV><FONT size=2 face=Arial></FONT> </DIV>
<DIV><FONT size=2 face=Arial>We are trying to figure out how to set the jitter
buffer in NEC DT700 phones to 160ms. Or set the buffer for 16 10ms packets. We
have a template config we found on NEC's site that contains all the parameters
that can be set for the phone, but no amount of begging NEC support through
several layers of escalation has yielded a simple answer to what exactly are the
config parameters we want. The section they are in is easy enough to identify;
it should be one or two of the following parameters --</FONT></DIV>

<DIV><FONT size=2 face=Arial>The codec we are using is G711, so it's probably
among the default values, rather than the values aimed specifically at g722 or
others.</FONT></DIV>

<DIV><FONT size=2 face=Arial>Again, my apologies for sending it here, I have
been very hesitant to do so for days, but we are out of other options, and at
this point are just hoping that there is either someone who knows DT700 phones
or knows VoIP in general enough that they can identify what we need to set for
160 ms (16 10ms packets) jitter buffer.</FONT></DIV>
