I think the problem is some of the CPE can only handle static IP-to-IP 
SIP trunks - no UAC capable of answering 407 challenges or doing 
registration, which often go hand in hand.

Also, BYEs and CANCELs should not be authenticated;  that's silly, 
they're already anchored to dialogs for which there is known state. 
Only initial INVITEs.  Can you really not change that in the Metaswitch?
