Also a sip trunk account from any providers with  strong credentials will serve the purpose. Connecting to internet could be dynamic IP as provided by many dsl providers. This will not give any security risks as you will not open any inbound ports.<br>

Hi,<div><br><div>Considering the security aspect of SIP Trunk and the cost of dedicated TDM trunk, the cheapest option for you is to use your home PSTN line as TDM trunk.. </div><div><br></div><div>To do that buy a PCI FXO card for Asterisk and setup the routing in asterisk either directly to your lan SIP phone(Xlite) or via openser/kamailio to Xlite. You can route all calls from SIP to PSTN and Vice versa. You will be able to do international calls if your home pstn phone has international plan. </div>

<div><br></div><div>The disadvantage here is you can do only 1 incoming call. I believe you can do multiple outgoing call with FXO line. Good thing is you can test all your capabilities before making the decision for dedicated trunk from service provider.</div>
