I just changed extensions.conf to read:

/etc/asterisk/extensions.conf
[incoming]
include => sip-phones
exten => _5551212,1,Answer
exten => _5551212,2,Dial(SIP/6710,12,tr)
exten => _5551212,3,Dial(SIP/6710&SIP/6711&SIP/6712&SIP/6713,20,tr)
exten => _5551212,4,Voicemail2(u6710)
exten => _5551212,5,Hangup
exten => _5551212,104,Voicemail2(b6710)
exten => _5551212,105,Hangup

and restarted asterisk for good measure. I am still not getting any ring on the calling end.  Anything else I should check?
