Hey guys, We have a brand new Dell Poweredge 1850, Single Proc 3Ghz, 2GB RAM, 15K RPM HD's RAID 1. We also have a Sangoma 4 port T1/PRI card. We are not using G729. Everything is G711. Every call is PRI -> Asterisk G711 -> Sip Carrier We just filled up 2 PRI's and reached a CPU usage of 70%. There's no way we can do 4 PRI's worth of traffic. Will a 2nd CPU

Is it possible to include a factor in an nls formula? I've searched the help pages without any luck so I guess it is not feasible. I've given it a few attempts without luck getting the message: + not meaningful for factors in: Ops.factor(independ^EE, a) This is a toy example, my realworld case is much more complicated (and can not be solved linearizing an using lm) a<-as.factor(c(rep(1,50),rep(0,50))) independ<-rnorm(100) respo<-rep(NA,100) respo[a==1]<-(independ[a==1]^2.3)+2 respo[a==0]<-(independ[a==0]^2.1)+3 nls(respo~independ^EE+a,start=list(EE=1.8),trace=TRUE) A...

...ually use virtual machines a lot for isolation and easy backups and migration (when a hardware node is underpowered, it is easy to migrate one or more virtual machines to another hardware node easily). I have looked at iSCSI and drbd for high-availability of the storage: http://www.pcpro.co.uk/realworld/82284/san-on-the-cheap/page1.html. This looks like it should be doing a great job of high availability storage. For mail server, I guess I should look at an MTA and IMAP/POP server that supports LDAP and/or MySQL for users. Postfix should be a good choice for MTA, as I know it (at least a lit...

This is so frustrating. Is RoR that easy to learn or is it hype or is it just me? I wonder how many newbies like me are surfing the docs trying to get a clue of the basics. Every tutorial I find is much the same, and seems to skip the fundmental parts. How should you understand the Ruby API http://api.rubyonrails.org/? What is < ActionController::Base? Can''t I set a cookie under

Hello r-proffessionals, this is not a special R-Question, but have anybody a good reason for nonstatistican's why the interpretation of correlations with cases under 20-30 are dangerous !? ...i have got problems explain this without formula's and perhaps anybody know a realworld example what point this problem !? thanks for any suggestion or url/doc etc. Christian Schulz -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or...

Hey guys, I'm looking for some realworld specs on somebodys machine that will work with the Digium 4-port T1/PRI card and that will support 96 simultaneous calls. Dell is soon to release the PowerEdge 1850: 2U, Dual 3.6Ghz Xenon, 1Gb DDR2 RAM, Dual 36GB Ultra320 SCSI RAID, Hot swap Powersupply, one 64bit 133Mhz PCI and one 64bit 100Mhz P...

...ter and this combination fits my budget. Has anyone else used colomachine with asterisk? how has it performed? I plan to run the latest trixbox on it with the RAM upgrade to 1GB. Should I go to the 2GB RAM? Will this combination handle all 4 spans at full load? I'm mostly intrested in realworld experiences. I hear a lot of "don't trust because of the cheap price" but when I talk to actual users they seem quite happy with these servers. Your opnions please. Mark C.

Hi, I'm coming up with ideas about building a cluster of asterisk servers, and am exploring the virtualization option. I'm curious to know some real-world data about how many extensions a VMWare install on good hardware could support. I've seen stories about how the hypervisor timeslicing can wreak havoc on call quality at some point. Is this really the case? If so, what's a

Hi List, I am trying to plot a grid with an overlayed height. I have a dataframe with four variables: x,y,gridvalue,height. The dataframe has 2.5mio observations (ie grid points), I assign colors through the gridvalue using map_color_gradient thus producing: x,y,gridvalue,height,gridcol as variables of the dataframe. The grid dimensions are 1253 x 2001 (=2507253 data points). My attempts with

Nothing special, just my first plugin. it came out of a request I saw on the list from someone who wanted to be able to tell if a model''s attributes had changed prior to being saved. Well, this plugin does just that (at least I hope it does). http://rubyforge.org/projects/actsasmodified/ Please see the README for details. Constructive comments and criticisms are appreciated.

...t their _external_ (64.x) IP''s from internal hosts, on the DMZ _and_ the LAN. (Is this correct? I don''t believe I''ve messed up so far, but I''m not certain.) This is important, so that people on the lan can access their mailserver (in the dmz) by it''s realworld IP address. Thats part of what I''m having trouble with though (more on that in a bit). Next, I''ve got some ports forwarded, from yet another external IP, to a couple internal hosts. Here are the relevant lines from my /etc/shorewall/rules (there are many more, but they are all...
