The issue you are having is your outbound nat type. The outbound mac should
be automatic for the entire network with the exception of the sip server.
Siproxd Will only make things worse. Your outbound nat type for the sip
server should be Manual But not for the whole subnet Which should be
automatic.

I have never had a problem Registering multiple trunks to the same Provider
Or using multiple providers in this fashion. And yes, I use pfsense quite a
bit in this method.
