I finally gave up chan_sip for chan_pjsip and it was fine

At the same time, if you know the IP of the device (which you must if you are putting a match=IP) then why register. Just set it up as a static IP trunk and be done.

It’s a static DHCP assignment, so I could, but I’m a fan of registered trunk connections where possible. Nevertheless, it’s clearly a bug that’s trivial to fix yet it’s sat unassigned for 11 months.
