When skype is installed, you need to buy skype-out credit which allows you to call normal and mobile phones. This works great. – Vilmantas Baranauskas May 10 '11 at 13:40

SIP Clients

These all are SIP clients which means they all can be used to call each other and they just need a SIP address (like your mobile number) . You can also register to a commercial VoIP provider(which supports SIP) to place calls to normal phone line or cell phone .

You can get a free SIP address from here.

PC to Phone calls in ekiga .

Default provider

The default provider is Diamondcard Worldwide Communication Service, which offers these rates

  • To purchase the account, go in Tools -> PC-To-Phone Account. You absolutely need to purchase the account from the PC-To-Phone configuration window or it won't work.

  • Once you have opened an account, login to your account to look up your Account Number and PIN. Don't confuse these with your username and password! Enter the account number and PIN in the appropriate fields in the window and enable the PC-To-Phone service.

  • If you need to edit the account under Edit->Accounts, you should use account number and PIN here also, even though it says "user" and "password".

  • You are now ready to do PC-To-Phone calls at very low rates all over the world.

Link info about the PC-to-phone aspect. – Oxwivi Mar 10 '11 at 9:25
@Oxwivi SIP can do PC to Phone so there is no need to keep asking for links. – RolandiXor Mar 10 '11 at 15:21
@Roland, I know it can, but whose service do we use for it? – Oxwivi Mar 10 '11 at 15:29
@Oxwivi that's up to the user, since Yate supports more than one service, and most of them support that feature. – RolandiXor Mar 10 '11 at 15:34
@Roland, that's the thing, I did not find those services, and I'm asking for a link that tells me what services supporting yate are available. – Oxwivi Mar 10 '11 at 15:37

Skype works in Ubuntu, but it's not FOSS.

You can use G-mail as sagarchalise suggested, and you can make calls out of the U.S. for free if you download the Firefox add-on AnonymoX it helps with tricking your system into thinking it's in a different country.

That only seems to work on America, as far as I know. – Oxwivi Mar 7 '11 at 14:45
USA and Canada can be called for free. Other countries list with rates are here – sagarchalise Mar 7 '11 at 14:57
You cannot use it outside of the US/Canada. – RolandiXor Mar 7 '11 at 16:21

The can install something called a "softphone" and then you can connect over "sip" to termination services (such as google voice) which act as the gateway form internet to phone networks so you can connect w/ real phones.
