When I bought two Polycom 501 SIP phones, I naively thought they were Power-over-Ethernet (IEEE 802.3af) because they were "powered over ethernet." Silly me. Polycom must have some odd voltage or funny way of injecting the power, because the POE switch I bought for them (Netgear F@510P) won't power them, though if I use the Polycom-supplied AC adapter and ethernet power

if I want to specify y-coordinates for the heights of horizontal lines to go across a plot. x <- c(1,2,3,6,4,8,4,7) y <- c(3,2,7,4,5,4,5,6) h <- c(3,5,7) plot(x,y) abline(y=h) However I got error message: Warning message: parameter "y" couldn't be set in high-level plot() function (I tried abline(h=y) , it;s not what I want also) Do u know why?

I was just getting to work on fax for my * system, so I thought I would bring everything up to date since there would be some new compilations involved. yum update gave me kernel-2.6.16-1.2069_FC4 but after recompiling zaptel, I kept getting "FATAL module zaptel not found" Chased this for an hour with multiple recompiles and reboots. Finally dropped back to 2.6.15-1.1833_FC4,

Hi, I'm try to compute the minimum sample size needed to have at least an 80% of power, with alpha=0.05. The problem is that empirical proportions are really small: 0.00154 in one case and 0.00234. These are the estimated failure proportion of two medical treatments. Thomas and Conlon (1992) suggested Fisher's exact test and proposed a computational method, which according to their table gives a sample size of roughly 20000. Unfortunately I cannot find any software applying their method. -Does anyone know how to estimate sample size on Fisher's exact test by using R? -Ev...

..., but FTP does the job. Check the docs for supported FTP servers -- many of the stock Linux FTP servers will give the exact problem you discussed, below. I should know -- took me almost a week before trying proftpd, and WHAMMO, worked like a champ. -Ken On Tue, March 7, 2006 12:37 pm, William M Conlon wrote: > I spent a weekend battling similar issues with 501s, using FC4/ > proftpd.

Hello, I was trying to import data from an Excel file. After I imported the data, I was trying to make a scatter plot. The X axes variable is a time variable, which occupies two columns, one is date, another one is time. Example 21-Apr-03, 4:10 PM. My qestion is: 1. How can I access the data of certain column? I mean how can I refer it in R? 2. How can I make the two column character

...tem rsync can cope with? Or the length of the filename? If so, how can I increase it or simply have rsync ignore paths or depths greater than the maximum, rather than just exiting? If there is no limit, how can I overcome this problem? Many thanks for your help in advance. Kind Regards, Daniel Conlon

Hi listers, I am looking for people who have used Power over Ethernet switches, primarily in conjunction with Polycom IP 501's. I've been looking at the Linksys SRW224P, since I've had good luck with the SRW224 in our office. However, Nortel, Cisco, Adtran, etc. all have an offering, all of which vary in price. I would appreciate any input people have to offer. Thanks, James

How can I deal with missing values in the excel file? I used read.csv to imports data, how ever there are missing values in the csv file. When I use names(), it turns out a error message: " names attribute must be the same length as the vector" What can i do with the missing values? Thanks --------------------------------- [[alternative HTML version deleted]]

I've got two Polycom 501s in an Asterisk 1.2.6/zaptel 1.2.5 with Digium connected to POTS. My legacy key system is still running in parallel. Today my 501 didn't ring on an inbound call, nor could I call out. sip show peers showed no ip address for my 501. Rebooted the phone and it's ok now. There wasn't anything enlightening in /var/log/asterisk/messages. Has anyone

Hello, I have started having a strange problem. Asterisk is connected via 4 analog lines to PSTN and we have SIP phones internally. All was working fine but recently each time a user calls from PSTN and when he is leaving a voicemail for someone, the caller gets disconnected after 30 secs. We have AMP installed. This is reproducible and is happening always. It seems that Asterisk is disconnecting

Hello everyone, Please forgive the exclamation points but I have been battling this one off and on for about four days now. Sorry for the cross post. It all started with a box of IP 501s. I contacted my reseller and obtained the latest BootRom and SIP firmware. Unzipped, configured, copied over to my FTP server (running AstLinux, of course). The phone booted, so far so good. Updated
