[asterisk-users] How to connect asterisk PBX to PSTN

[Jigar Joshi]

Thanks Gopalakrishnan ,Sebastian,Josef,

Actually My Requirement is :

I need a international number all network should be able to connect to it.
After ringing a ring call should be picked up. and should ask for a code.
code should come from mysql or any other DB
depending upon the code it should route the call to an application where it
converts SIP to my protocol and vica versa.

I am confused about the implementation. design is clear ,

Your help would be really helpful.
