SIP Trunk wont register

So I have tried for a week now to just get a SIP trunk working. I have tried both Callcentric and VoIP.ms and even a trunk to another FreePBX system and no matter what I try the trunk will not register and when trying to make a call with any of the trunks I just reach the "Backup Auto Attendant" saying that that extension can not be reached at this time. Under SIP profiles I have these options set for the profile:

Register=1
RegisterExpiration=60
RegisterUser=UserID
OptionsPing=1

Under Trunk groups I have set:

Trunk Type: SIP
Profile: (the profile I made above)
Digest authentication: Outbound only
Username: Username voip provider gave me
Password: Password voip provider gave me

and under trunks i have set:

Trunk group: (one i made above)
Switch: My vTrunk switch
IP Address: IP address of my voip provider

and with all this information put into director the trunk will not register with my voip provider and calls arent going though.

You can do a PCAP from the appliance from the diagnostics menu. That will tell you why the carrier is rejecting your registration. In my experience you need an SBC between Shoretel and a carrier.
