The configuration described in
Single-Stage Dialing Through Any OBi Trunk will allow you to freely dial a number through any trunk of either OBi in either direction without using the Auto Attendant.
If you're wanting the telephone connected to the NJ OBi to be a hotline to a telephone number accessible from the FL OBi:
NJ OBi:
Physical Interfaces -> PHONE Port -> DigitMap : (<S0:**9200654321>)
where 200654321 is the OBiTALK number of the FL OBi.
FL OBi:
Voice Services -> OBiTALK Service -> InboundCallRoute : {200123456:li(12341234567)},{ph}
where 200123456 is the OBiTALK number of the NJ OBi and 12341234567 is the FL telephone number to be called.
As soon as you pick up the telephone connected to the NJ OBi, it will connect to the FL OBi which will immediately initiate a call to the FL telephone number using the LINE Port.
