Asterisk newbie

please i need help. I am new to asterisk and i have configured it for internal use in the office. The problem is making calls to outside networks. I have tried the echo test and it responds but i still cannot make calls. I need help and fast. here is my iax2 config

[iaxfwd]
type=peer
context=fromiaxfwd
auth=rsa
inkeys=freeworlddialup

Thanks
Oge

what are you going to use for calling to outside networks? Like analog lines, T1 channels, …? Do you have any hardware boards, like TDM PCI cards?

For IAX and SIP you need some way to connect to PSTN network.
