Incoming call comes in twice

Newbie to FreePBX and Asterisk. I have a test system with two SIP trunks coming in. I can dial out fine. I have an incoming route setup to go directly to my extension. When I call the DID, the call come in, I can answer it, and while in the call (or if I hang up), after a few moments of the original call coming in the same call will come in again.

I’m calling in on my cell phone to myself basically. The call comes in, I pick it up, I can talk/hear both directions, but after a few moments, the same call comes in again, me from my cell phone.

Any ideas? I’m happy to post any config info, I’m just not sure what to post. Thanks.
