[Asterisk-Users] RE: Snom high SIP ping time

[Mike Hammett]

Well, it wasn't so much of a command line ping on the SIP port, but the 
times reported under Status when qualify is set to yes.

It should be far less time than that as the time from that PBX up to my 
server out on the public Internet is only 10 ms away.  I have servers in 
other parts of the country that are only 55 ms away.

If you ping on the SIP port the message has to go through the
application layer - which takes some time considering it is an embedded
system with a small CPU. That part should be ok.

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 image (http://www.snom.com/wiki/index.php/Beta_Firmware).

Hope that helps, CS
