How to start a phone call

[Raccoon29]

Hi everyone!

I just have to start a Skype call when clicking on the PushButton related to a VoIP number.
The question is:
How is possible to achieve this?
Could be to post a 'callto' an idea? If yes, how could I do it? If no...well, sorry
Any suggestion is well accepted!

Thank you in advance to everyone will help or not!

Maybe QDesktopServices can help you with this.
Otherwise, maybe you can use QProcess and start/pass a parameter to Skype to start a call. If Skype doesn't allow multiple instances, then trying to open a new instance causes all the params passed to the new instance to be passed to the old instance. I guess you should document first on skype command line parameters.

Did you check the skype SDK? Maybe there is something as easy as calling a function
Check out their site, there must be a link there somewhere with the documentation.

Thank you for answer!

I am going to check both of your hints, anyway some people told me that all I need is to send a "callto:+390123456789" to a browser in order to obtain an internet call that automatically uses skype to call it.
So while I check your suggestions, could you please tell me how to post this sort of messages? (I refer to the callto ,or mailto , is the same )

Thank you so much!

QDesktopServices:: openUrl("callto:+390123456789");

Ehm, sorry marcel,
but QDesktopServices has been introduced in Qt 4.2 and I am using Qt 3 (as the thread says) ...
so, are there other ways to achieve this callto ?

Sorry about that. I always miss it.

The correct form of the URL is : "callto://{phonenumber}", like "callto://123456789".
When you install Skype on Windows you have the option to associate it with the "callto://" protocol.

To make a call, just use( not tested )

ShellExecute(0, 0, "callto://123456789", 0, 0, SW_SHOWNORMAL);

ShellExecute(0, 0, "callto://123456789", 0, 0, SW_SHOWNORMAL);

To copy to clipboard, switch view to plain text mode

Thank you, always so kind

I'm going to test it and report soon.

Sorry but ShellExecute results undefined...
so where is it defined?

PS: I tried to include shellapi.h ,as suggested on the microsoft msdn site, and the compiler gave me something like over 100 errors inside "shellapi.h"... so I thougth smartly to have missed something...

[marcel]

Have you linked with shell32.dll?
If you're using Visual Studio you have to import shell32.lib.

But anyway, you can post the errors you get.

[Raccoon29]

Have you linked with shell32.dll?

No, I have not, because I'm not able to, I never linked a dll...

If you're using Visual Studio you have to import shell32.lib.

I'm using compiler Microsoft Visual C++ 2005 Express

But anyway, you can post the errors you get.

I don't think it could help: at 100 errors compiler stopped saying they were too much, and analysing the errors given they seems to say that that "shellapi.h" is written in some language else c++, a lot of undefined symbols and messages like:
''default-int'' is no longer accepted in C++ or sim.

In this post I can't, but if you want I could post the errors in the next message.

Thank you for your time

Include these instead of shellapi:

#include <windows.h>
#include <shlobj.h>

#include <windows.h>
#include <shlobj.h>

To copy to clipboard, switch view to plain text mode 

[Raccoon29]

It works!

Thank you marcel!

Just one note for those will follow this thread: there is needed an "L" before the number to pass, that should make it compatible with the LPCWSTR Windows type.
Code is:

#include <windows.h>
#include <shlobj.h>
 
void callVoip()
{
     ShellExecute(0,0,L"callto://+390123456789",0,0,SW_SHOWNORMAL);
}

#include <windows.h>
#include <shlobj.h>

void callVoip()
{
     ShellExecute(0,0,L"callto://+390123456789",0,0,SW_SHOWNORMAL);
}

To copy to clipboard, switch view to plain text mode 

this will automatically start the voip client making this call (if configured to do it).

Thank you all again!
