12222222222 & 13333333333 will be blocked. All other CallerIDs will ring the phone.
My suggestion above results in your OBi sending SIP message "486: Busy Here" back to your voip provider. FPL sees that message and diverts the call to your voicemail.
As Shale suggests, you could divert the call on to a free message line to annoy the caller so much that they give up calling you. This requires some setting up. I'm assuming that you have FPL on sp1 and sp2 is spare.
1. Set up sp2 as a "fake" provider:
Service Providers -> ITSP Profile B -> SIP -> ProxyServer : 127.0.0.1
Service Providers > ITSP Profile B > General > DigitMap: ([^*]@@.'@'@@.)
Voice Services -> SP2 Service -> Enable : (checked)
Voice Services -> SP2 Service -> AuthUserName : 12345678
Voice Services -> SP2 Service -> X_RegisterEnable : (unchecked)
Voice Services -> SP2 Service -> X_ServProvProfile : B
Voice Services -> SP2 Service -> X_UserAgentPort : 5471
Voice Services -> SP2 Service -> CallerIDName : Anything
2. Set up your InboundCallRoute:
Voice Services > SP1 Service > X_InboundCallRoute:
{(12222222222|13333333333):sp2(wbdemo@conf.zipdx.com)},{ph}
12222222222 & 13333333333 will be forwarded to
wbdemo@conf.zipdx.com. All other CallerIDs will ring the phone.
I picked
wbdemo@conf.zipdx.com because it's a long message about wideband calls. It goes on and on and on ...
