Help with Setup

I am trying to setup a basic two user system with “followme”. I have configured some of the basic configs but I am getting hung up on certain areas such as trying to make outbound calls I get the error message:

-- Executing [1248XXXXXXXX@employee:1] Dial("SIP/200-00000071", "SIP/callcentric") in new stack
-- Called callcentric

[Dec 18 13:45:56] NOTICE[6212]: chan_sip.c:13027 handle_response_invite: Failed to authenticate on INVITE to ‘“Andrew” sip:1777XXXXXXX@callcentric.com;tag=as2f3a8219’
