[Linphone-users] linphone setup to call a phone number!

[Raja M.]

Dear ALL,
                                                                                                                            
I have installed new release of linphone-1.2.0, libosip2-2.2., speex-1.1.11-1, etc sucessfully.
                                                                                                                            
My .gnome2/libphone config file is shown below:
                                                                                                                            
My objective: is to use desktop "libphone" to call any phone number.
                                                                                                                            
I have registered tp www.voipuser.org and provided a US based number to call which is my branch office in US.
My linphone is istalled in Fedora 2  which is behind NAT with IP:192.168.200.40 and my NAT(203.197.12.30) has all port connections outgoing for 192.168.200.40. Incoming for port 5060(SIP, user agent) and 7078(RTP, audio) is enabled for 192.168.200.40 also.
                                                                                                                            
when I connect through Gnome applet, I get registration sucessfull , but How do I know that call is forwarded to my US office.
                                                                                                                            
Is that in DTMF, I have to enter the phone number?
                                                                                                                            
Pl, let me know that is this the way to connect to other phone device?
I need some help as I am new to this ..
                                                                                                                            
                                                                                                                            
Regards
Raja
