Getting constant "calls" from 100 and 10001

You have your Obi exposed to the "incoming" internet (Not good). As this has just started you probably made a change to your router, etc.
I did recently get a new router. UPnP was enabled. Could that have been it? I've since turned it off.

While checking "X_AcceptSipFromRegistrarOnly" can work, with some service providers it won't work. Some ITSP's send INVITE's from a different IP address than you are registered to and you won't get those calls. Another old fix for this has been around since the 100/110 days. Simply set Inbound call route to something like "{>1234567:ph},{?|@:}". Replace 1234567 with the user ID you have with your ITSP. Both the 200 & 202 have a check box specifically for this. If you have a 200 or 202 simply check X_EnforceRequestUserID. If the spammer doesn't know your sip user ID your phone won't ring.
*edited* If my memory serves me correctly, the user agent port for sp1 on the 100 series defaults to 5060 and sp2 defaults to 5061. I highly recommend changing both to another number [make sure both sp's use a different number]. I think this was corrected in the 200 series. Also, disable sp2-sp4 if they are not being used.
I looked through the settings and didn't see anything for user agent. Any idea where that might be? Also, in layman's terms, can you explain what its for?

Voice Services-->SPx Service-->X_UserAgentPort (change it to something between 20000 and 60000 making it more difficult for a SIP scanner to find and probe the particular port you are using)
User agent sends/receives SIP requests/packets. A user agent is your actual client: IP phone, OBi ATA, softphone, etc. X_UserAgentPort is the port number the SIP packets are actually transmitted/received on.
Quote
User-agent client (UAC)--A client application that initiates the SIP request
User-agent server (UAS)--A server application that contacts the user when a SIP request is received and that returns a response on behalf of the user.

That would have been a useful piece of information to include in your first post.
Go to the link below and proceed to Shields Up and probe ports 5060-5061 (must enter manually and hit Enter) on your public IP address. Status should be "Stealth."
You should also probe Common Ports or All Service Ports.
