I am new to VOIP and more specifically SIP. I want to sell phone and just use my laptop for communications using a softphone eg. Linphone. I still want to make and receive calls, SMS etc.
I travel a lot so I was thinking that i could get a virtual number that redirects to SIP provider that i could connect to via VPN using a softphone.
If this how it works, does anybody know of any good Swiss based SIP providers that support encrypted communications for example SRTP and SIPS ?
I have a feeling that it is not that simple so please please correct any misunderstanding i might have about the technology.
