SIP Registrations being denied

I’ve got an asterisk server out on the cloud and one behind my routerboard. Using the exact same sip.conf I get registration on the cloud asterisk but not on the physical one.

I keep hearing references to the SIP helper service but cannot find a single reference to its use.

Please advise. Thanks in advance for any help. :smiley:

Do you have the local asterisk nat settings INSIDE ASTERISK (not Mikrotik) setup properly?

nope. I actually had all the settings correct. the problem was fixed as I rebooted the router. LAME
