Thanks, I am seeing the same behaviour in sngrep. The second INVITE with auth has incorrect SDP.
Initial INVITE sent to Supplier has correct SDP but no auth as expected.
Second INVITE sent to Supplier has reverted to the original SDP as sent from my phone, but has got the valid auth. I expect to see the SDP "fixed" and same as the first INVITE.
