As a word of advice.

You will have to pay someone for the mobile or PSTN calls. It is very unsafe to open your system to the public without very good security, especially very strong user passwords.

There are constant attacks by robots that attempt to break into systems and get free (for them) calls. If they succeed it will be at your cost.

Hi,

I think you want asterisk help ! or is it related to iptel sip trunk ? Anyway here are few simple answers.

1- For asterisk you can install a Digium or Sangoma Card to connect PSTN lines to your server and make calls out to India using those PSTN lines. 
OR
1- As you said you can buy a local SIP trunk from some provider and configure it on your asterisk and use that sip trunk to make calls out to other countries, if that carrier allows you to.(mostly they do)

2 - To make your server public you need to assign a Public IP on it and your serevr will be directly on Internet.

Thanks,
Sammy

Dear Admin,

My name is Ameneh from India. I am new in SIP. I have installed asterisk 1.8 on my ubuntu system and could have registered the internal users in my LAN to talk over x-lite. 

Now my question is how can I make a call to a mobile in India or a PSTN number in another country that would require a public SIP I think. 
how can I make my SIP server as public? would you please help me? 

thanks and regards,
Ameneh
