Configure Asterisk trunk

Hello, I have a "friend" account on a server "A" for which I need to configure inbound and outbound calls from my own Asterisk server ("B") (trunk). I need Server B's both SIP and IAX2 configurations so that B registers on A and start sending and receiving calls from a SIP softphone registered on it. I actually only need the proper [login to view URL] and [login to view URL] specific configurations from server B + the specific inbound context for extensions.conf. You will not have access to the servers so you need to be able to test it by yourself. I will only provide the account info for proper registration on server A. It needs be tested this way: - SIP softphone registers on B and make a SIP outbound call through A - SIP softphone registers on B and make an IAX2 outbound call through A - Will call account on A so that calls transfers to B via SIP and make SIP phone rings - Will call account on A so that calls transfers to B via IAXs and make SIP phone rings Account info provided when project is awarded Thanks
