You are correct, I'm using DNSSRV. 

imho it's a bug when FS is not using the same nonce in the response as it received in the request. It might be a design flaw only that only appears when running against multiple servers through DNSSRV, but it's still a bug.

I'm sure it's easy to fix for Anthony with his m4d sk1llz ;)

Your problem is not a bug. The problem is that your SIP provider has two
proxies (that you probably find via SRV). Instead of using one gateway
profile that selects either of them, you have to configure both gateways
as separate elements. That way FS will use the nonce it gets in the 407,
instead of mixing them up between the two proxies (who don't have state).

You either use one gateway for outbound and the other one as failover in
the bridge app, or you use mod_distribute to distribute.
