This one is a longshot but I'll give it a try anyway.
I recently bought this USB Telbox device (AKA yealink USB-B2K). It's a device that connects to a PC over USB and to the PSTN (home telephony) and regular phone device over RJ11 cable. The device is used to direct incoming PSTN calls to the skype client running on the PC and to make calls over skype by simply dialing the keypad on the regular phone device.
This is all nice, but I was wondering if it would be somehow possible to use this device to make calls from the PC over PSTN. Now, the device can make PSTN calls when dialing on the regular phone's keypad (hitting '*' on the phone's keypad make it switch from calling over skype to calling over PSTN). My question is whether it would be possible to control the device from the PC over USB and make it make a call on the PSTN.
Asterisk has a usbb2k module that has been reported to work. (You do realize that Skype has security issues, such as punching holes through your firewall, right?)

I haven't tried ModemManager yet, but it seems to me that it won't work with a phone plugged into the laptop, unless there is some software running on the phone that acts as a middle-man between ModemManager and the phone's modem.
If the phone is plugged in a laptop it may happen that it already exposes an "already connected" eth over usb (and therefore ModemManager won't be used) or instead an AT-capable serial port (which ModemManager can use to get a connection).
I've been asked to work on a project for Windows 8 where I have to detect:
Type of device inserted to USB port (mass storage drive or android phone or windows phone etc.)
Port in which device was inserted. (if I have 4 USB ports in PC then identify which port received new device)
Detect when the device was ejected from the PC
Are there some managed C# API's that can be used to query or if there are some callbacks that can be subscribes to.
Any help or direction will be very useful.
Thanks
You don't specify whether you are writing a desktop app, or a Modern UI app. If it is the latter, I'm afraid you are going to be out of luck as this level of information is simply not passed down to the app's sandbox.
You may have better luck with a desktop app. I don't have any direct experience of doing what you ask for, but I do remember having read that it may be possible through .NET.
This is technical question to check the possibilities of the scenario. Is it possible to use Nokia phone's (Lumia, N9, symbain phone, S40) 3G data connection with a Android tablet pc?
Or any way to use phone's 3G data connection with tablet pc?
I have a unlimited data connection for my phone. But I don't use it that much. So I'm planning to use it with the tablet pc.
yep its possible easily if :
1. your tab is rooted
2. your tab supports usb host mode or otg mode (you could either check it on net or download usb host diagnostics) (just click start diagnostic)
procedure
Downoad ppp widget
configure your apn according to pc suite settings
then plug in your phone via usb on nokia pc suite mode
now wait 10s and click connect
you are now done
(pls switch your wifi off as ppp widget creates virual wifi for your tab)
any inquiries contsct rld0989#gmail.com (don't be rest less I only check my gmail once a day)
Yes, it's possible to use your phone as a modem, connected to the tablet via a USB cable, as long as you have
(1) an APN from your network operator to make a data connection via their network, and
(2) suitable device drivers for the phone. On Windows, smartphones are plug and play, but I don't have any experience using them with Android.
On the tablet, you also need some software to control the modem - something like the Mobile Broadband Connect 3.0 application listed on here
You can write a simple connection app yourself using the Android Telephony Manager.
Alternatively, you could connect manually, using AT commands with a suitable AT command program (in Windows, it would be Hyperterminal). This thread describes a possible equivalent for Android.
Standard AT commands to make a data connection are described in the 3gpp TS27.007 specification.
There are a lot of variations for different manufacturers, but making a simple connect should be possible using the standard commands.
Preferably, this would be a computer connected via cable, but if there's a way to do it over wifi then this would also be useful. I'm wondering if it's possible to send messages between them?
Or if i had a mac app and an iPhone app, could I communicate between them over wifi or a usb connection, rather than using a server or something?
Connecting over WiFi is possible, cable connection however isn't possible (certainly not in the documented API) unless the phone is jailbroken.
For wifi you're just going to connect to a TCP/IP host/socket. Have a look at CocoaAsyncSocket. The computer would need to be hosting some sort of server software. This is how iTunes Remote and AirMouse work.
There are some "permitted" (non-cracked phone) ways to send data to the iPhone from a device that's physically plugged in. There are several barcode readers - like the Linēa-pro used in US Apple stores - and magstripe readers for credit cards (e.g., the Macally Quikswipe) that can send limited amounts of data to/from the iPhone.
If your computer is a small embedded device and your data requirements are meager, it may be possible.
I have a Nokia Symbian Series 60 3rd edition phone. I can use it as a GPRS / 3G modem either using Bluetooth, USB or IR.
Is there a way to programmatically detect when the phone is being used as a modem?
Please note I don't want to detect when a GPRS / 3G connection comes up (such as when you use the phone browser), but when a GPRS / 3G connection comes up that is the result of the phone being used as tethered modem via BT / IR / USB.
So the user has set up a dial up networking connection on their laptop, for instance, which uses the modem in the phone. They then launch that connection because they want to make a 3G wireless internet connection from their laptop via the phone. That's what I'd like to be able to detect from the phone.
I don't believe there's any public interface that you could use for this. You could probably use internal APIs to check what is creating the data connection, or more crudely check which processes are running when a data connection is created - probably quite easy to fool this method, depends why you want to know?
I can see network operators wanting to do this to block and/or charge extra for tethering usage. Easiest way to do that would be network side though, checking the browser UA header (also possible to fool, but not without harming your browsing experience a bit on the laptop).
