...suck hugely. Unless echo is your goal, you are not going to be pleased. If you have to use 24 existing POTS lines, look into a channel bank and interface it to a T1 card. If you are planning new, just get a PRI T1 and be done with it.

Hi, Some days ago I am interested in detecting undefined behaviors in C programs based on Clang. After several days’ investigation, I think checking bounds overflow bugs is more interesting, because bounds overflow is one of the most frequently encountered errors in C programs. For example, performing pointer arithmetic without checking bounds can cause bounds overflow. To increase the accuracy of finding bugs, I want to write several passes, ba...

Hi, I have to recognize that i don't fully understand the aggregate function, but i think it should help me with what i want to do. xveg is a data.frame with location, species, and total for the species. Each location is repeated, once for every species present at that location. For each location i want to find out which species has the maximum total ... so i've tried different ways to

Hi, I am very new to Ruby, but I know I can express myself in writing pretty well. If it''s OK to contribute to the documentation of WXRuby, How do I do that? I signed up for a membership on Sourceforge, but was not sure what to do after that. Thanks.

Hi, I am just trying to figure out how to setup a TDM04B card for incoming/outgoing calls. I have 4 lines, which are provided as a rotary trunk group, currently hooked into a Nortel system, which asterisk will replace. I have setup a Dell 1800 (Tower) system with the TDM04B card, which seems to work. The question is how do I set it up that all 4 lines are part of a trunk group, such that

Hello, we're setting up a weird platform where every incoming email is passed from the MTA directly to a tool that then uses dovecot LMTP to deliver the message into the user mailbox. We are legally *not* allowed to run antispam on all the incoming messages, but only on some of them, as they are recognized by the aforementioned tool; but given that tool directly uses LMTP to delivers the

Dear colleagues, Saving a plot with pdf gives a very nice result: pdf("myplot.pdf") par(font=1,family='serif') plot(pressure) dev.off() Doing the very same with other formats (png, jpeg, tiff) gives far worse results. Is there anything to do to make a plot in some other format than pdf look like the pdf? Hardly any journal accepts pdf files for figures, and most do accept png

Hi All; Again, the Cisco IP Phones 7942G and using Skinny: I upgraded the firmware to version 8.5 (skinny) and I am using skinny channel (chan_skinny) and the skinny.conf file. The phones are registering, but when we use them to place a call, we only hear tooooooooooo in the handset and we do not hear voice (even when we dial the digits, we only hear toooooooo .. but it dials and destination

Hi, we are developing and operating an very critical application in the financial sector. Now our customer wants us to report performance data (roundtrip times of the messages routed). My idea is using dtrace to measure the times with the pid provider catching the timestamps on entry of the in and out functions of the processes. Now my questions ;-): 1) Is this an appropriate method to monitor

Hello, I suggest Darwin Steraming Server. Apple's Darwin Streaming Video Server is pretty good and open source...(It uses RTSP protocol and supports Linux,Mac,Windows) RealServer is not free(there is connection and year limitations....) but powerfull..(uses RTSP, supports Linux, Windows[memory eater :)) ]) Also there is Windows Media(uses HTTP(performance is very bad), supports only

Hello, Sorry but in the mails I have read I did not see any "shout" program comments. I have configured icecast and I am using "shout" to encode MP3s. Is the performance of shout bad or others are better then "shout"? I did not encounter any problems yet. Thank you for any comment.

Hello, Could the experienced people help me? 1:) Is it possible to start liveice in the background like icecast and shout?? 2:) If I insert another sound card to PC(it will have 2 or more sound cards). Is it enough to specify "SOUND_DEVICE" option to /dev/dspX in liveice.cfg and start another liveice session with that configuration file??? 3:) With many efforts I fail to start darkice
