Elastix T1 outgoing call not ringing

That would make me think that you have the r option on the "Asterisk outbound dial command option" (PBX -> General Settings),

 By using r on Dial, you are forcing the sending of AST_CONTROL_RINGING, and therefore 180 Ringing, even though no out of band ringing indication has arrived. This will cause the actual SIP phone to generate ring back tone.

What I'm suggesting is that using Progress will force the use of early media on the caller's side, which will, hopefully allow it to hear the actual ring back tone arriving from the public network.

Thank to: http://www.msserverpro.com This process of removing data in AD DS is known as Metadata Cleanup. NTDSUTIL is used to clean up domain controller metadata.
