I am having trouble registering a snom m9 (not the softphone) on the pbxnsip cs410. I now get a message about a password being incorrect (was previously getting 404 not found), but cannot figure out what it is using to try to authenticate (and don't really understand why this is required for the m9 when it wasn't for the 300, 320, etc.). The latest registration log is below. Any help would be appreciated.
