the application layer - which takes some time considering it is an embedded
system with a small CPU. That part should be ok.</FONT></SPAN></DIV>

color=#0000ff size=2>It the phone becomes choppy, that problem is probably
related to the RTP side. Maybe you have different packet sizes for incoming and
outgoing traffic. You can get an Ethereal trace from the web interface of the
phone which should show you the RTP jitter (PCAP trace). Or use a hub if you
don't trust that trace. 6.1 is the latest version if you want to try the latest

SIP ping time<BR></FONT><BR></DIV>

<DIV><FONT face=Arial size=2>I don't know everything that's going on as
someone else has been working on the project, but it hasn't really been going
anywhere, so I had some questions.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>We've got some Snom 320s with Asterisk 1.2.9.1 (I
believe). All was well (with a previous release), but the phones started
to get real choppy. We are also running a softphone at this location and
it was fine. The SIP qualify was returning ping times anywhere from 20
to 70 ms over a sparsely used LAN. Command prompt (ICMP) pings were
under 1 ms. No amount of different Asterisk versions or phone firmware
revisions seems to solve this. All was well, then (as far as we know)
without changes, it crapped out.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any ideas?</FONT></DIV>
