I just installed a Sipura SPA-1001 on my home network, which has a couple machines connected via a simple 4-port linksys router and DSL box to the internet. I was able to call PSTN numbers from the SPA-1001 but not the opposite. I tried the 1-747 number I got from them but could not reach it from my landline. What is needed in order for that to happen? Is this only possible nowadays via paid services? I hooked the sipura ata via sipphone.com and they seem to suggest that on their site
