No, You can use one but you could also install a hardware PSTN/ISDN card for receiving and making calls via your TelcoHello List!
I just read an article about asterisk, and i would like to ask a few questions to see if i understood the principle right. Reciving Calls: --------------- - To be able to recive calls, i need to have an VoIP-Provider.
If you want to receive calls via a VoIP provider it makes things easier if your address is static.- I need a Static IP, so that the VoIP-Provider can redirect the call to my office/asterisk server.- asterisk will then forward the call to my phone
Otherwise you need to register your address with the providers system each time it changes, I dont think this is an automated feature of asterisk.
See Above a Hardware interface can do the trick
Making Calls: --------------- - To be able to make calls, i need to have an VoIP-Provider.
- I need an account from a VoIP-ProviderIf you want them to take your traffic.
Yes, unless you have a hardware interface then it goes SoftPhone -> Asterisk -> Telco- A call from a Softphone/Office will be made to the asterisk server, which will then forward it to the VoIP Provider, which will then transfer it to the normal telephone network.
Correct to far?
Thanks, Mario
