I’m not very familiar with VoIP telephoning.
I want to make a simple call to a phone number in my country (Bulgaria, +359) and play some music.
Until now I used a SIP accont from Flowroute (using sip.conf configuration).
Everything works, but now I want to be my own SIP provider.
Is it possible?
Can I just attach some VoIP device to my linux server and start making calls?
