What you need is an FXO card for your PC. This is a PCI card with a phone socket in it, and it effectively works as a PSTN (public switched telephone network) phone on a card. You plug this into your wall socket just as you would a telephone. Then you use PBX software (such as Asterisk) to mediate the calls. You would need a way to interact with the PBX, ...

I'd like to say, this does not answer your question directly, but I think you're looking at the problem the wrong way. Do you really want a 400 Watt computer running all day just to screen a couple phone calls? I think Both "what do I do with a Pentium I" and "How do I screen calls" are both excellent questions, but IMHO I think you should split these. Im ...

Yes, there is a software/hardware that can achieve this, and relatively cheaply. Asterisk is an open-source (free) PBX software, that can do what you need, and more. Asterisk is usually used on linux, although there are pre-packaged virtual machine appliances available. There are also lots of Asterisk-derivatives, like PbxInAFlash, TrixBox, and others, that ...

The simple answer is no, you cannot make a typical computer into a PSTN-connected PBX without a new piece of hardware: an "FXO card". An analog modem cannot perform as a voice-service FXO as they are designed only to process data bits asynchronously (i.e., V.92 protocol) – that's why modems are much cheaper and more common than FXO cards. A LAN card's port ...

If you use Chrome as your browser, then you can get a Google Voice account and the Google Voice extension. Then you'll be able to click on a number and it will route it to your phone.

While not a direct answer to your question, someone has accomplished something similar to this using a Raspberry Pi. Their full article can be found here but the summary is that they've used a phone to Ethernet adaptor (like the one @Rich Homolka mentions in his answer) wired in to the Pi and a couple of scripts to make sure that the caller is a person or ...

According to airplane security regulations, you are not allowed to use cellular connections on an airplane. As far as I know, it is technically possible to make phone calls (via the 2G network). 3G has lower range, so it could be impossible to connect from that altitude.

You can listen to the line using Hayes A.T. commands: Open up Hyperterminal (if running Windows) and connect to your modem's COM port (usually COM3). Type ATM2 and hit enter. This will enable the speaker. Enter ATH0 and hit enter to 'take the phone off the hook'. You should hear a dial-tone. This should work if you are being called. I know how to dial ...

You could try going into the Device Manager and setting the device to disabled.

Check out iCall. You must call within the US or Canada to use it free.

You can plug standard "square" RJ14 cables into a RJ45 jack, as long as the port is wired to your phone line. It should click in. You need to figure out which ports are wired where.

Sure you can do this. Hook the modem up to the phone line. You will need a terminal program to control the modem. Granted, I havent seen one in years and MS doesnt include one with Windows anymore, but Im sure if you google it, you can find one. You might even be able to pipe the command "ATA" to the COM port in command window. FYI "ATA" is the Hayes ...

In a past, evil life I worked on the technical side of the telemarketing industry. I'm sorry. Something that works very well is to quickly stop the caller in their tracks and say, "Please add me to your do-not-call list." By law they have to stop what they're doing and add you to the list. Sometimes they'll ask if you're sure, but that's about it. Just ...

Allow me to answer your question from a purely technical point of view. This is what I would do if I was in your position and sharing your motivations: Google the modem and download the technical info - if you can't find any then it's probably too much hassle. While you are at it download the reference on the Hayes command set (AT commands, etc) blow away ...

Look at the SKINNY (SCCP) protocol: http://en.wikipedia.org/wiki/Skinny_Call_Control_Protocol. It is a binary protocol (as you can see in your Wireshark captures), so you can't use PuTTY to command your phone with AT-like commands. Typing hex digits in PuTTY is useless, as the data that is transmitted in the packets is not the hexadecimal digits, but the ...

You might try running Asterisk, which is: Asterisk is an open source framework for building communications applications. Asterisk turns an ordinary computer into a communications server. Asterisk powers IP PBX systems, VoIP gateways, conference servers and more. It is used by small businesses, large businesses, call centers, carriers and ...

Asterisk is free and a simple FXO/FXS adapter with 1 port like you need won't cost $400. Try looking for linksys SPA3102 for example and an example config. You don't need to buy expensive multi-ports internal cards. Why don't you go SIP and need no adaptor, only the internet conection your BOX delivers? With Sip, you will receive the call for free if you ...

Resolved! In order to avoid this: I emailed a professor that I know, and he has resolved the issue - sad to say, e220 does not support voice calls. As per http://bit.ly/wSDoGW, I was able to check for voice compatibility in minicom: AT+FCLASS=? +FCLASS: (0-1) OK For voice support, the list of numbers returned by FCLASS must include 8 - thus, this ...

Every protocol has overhead. The "LAN" copy you're talking about it most likely SMB/CIFS. CIFS is quite prone to being badly configured(and thus slow) and overall has more overhead than FTP. FTP is a very simplistic protocol. It's hard to get it wrong. CIFS is a complex protocol, most likely the implementation on the phone is either limited or slightly ...

As emddudley said, it should plug right in. Just make sure you get the wiring correct. Plugging a phone into a jack wired for ethernet probably won't be a problem. Plugging a network device into a jack wired into the phone system is bad. Phones ring by having a voltage sent down the line, enough to ring a physical bell on old rotary phones. Network ...

I don't know much about the subject in question but i know that THE open source software to do this is Asterisk, it can do what you want and more, i'd search for compatible hardware for it.

You could use two modems with a Dual-WAN router, although load-balancing would be rather pointless in a home, in my opinion. Why pay for two broadband contracts?

It's possible to do what you want but so complicated it's probably not worth it and you are limited to 10/100 speeds on your LAN. 100Mbit Ethernet only uses 4 of the 8 wires in a Cat5 cable. They make "splitters" that give you two RJ45 ("Ethernet") jacks - one jack uses the first 4 wires, the other jack uses the second 4 wires. Put one on the other side ...

No additional hardware is no problem if your computer (modern notebook?) has a microphone and speaker. However, to reduce or avoid crosstalk, an earphone plugged into the audio out connector would help. There is plenty of software that can connect your microphone and speaker to asterisk, e.g.: Ekiga, Linphone. You don't like VoIP, but you call over voip ...

I've got a Linksys PAP2 which I use for British Telecom SIP VoIP. You could use one with Vonage, without having to need to turn your computer on. They are very cheap on eBay. There are also various Skype phones available on their website. I can only seem to link to the UK site here.

Have you tested all the ports? Are you sure there isn't an issue with a cable from the junction box to the punchdowns? You really need to isolate one piece at a time for a wiring issue like this. Think of the setup in individual components: Modem Cable from Modem to Junction box Junction box Cable in wall Jack/Punchdown at other end Cable from ...

I've seen devices at Radio Shack that allow you to record phone conversations--they just plug into the POTS handset and provide audio signal over a 1/4" stereo mini jack. You could plug that into the microphone or line in port of your sound card. Don't forget you need permission to do this depending on where you live.

You could try dialing in to the call using skype and recording the sound via your PC's Sound Recorder application.

Talk to your IT staff - apparently the same ip address is being given to more than one system - this could indicate that someone has your IP address set statically or DHCP is having issues. If its an issue, its with connectivity with your system as a whole, and is something your admin would need to look into - it WOULD explain the client not working, but ...
