VoIP Provider is Asterisk and get 405 Method Not Allowed

[meshuga]

It works great, but I'm flooded with:
[Jul 1 17:04:12] -- Got SIP response 405 "Method Not Allowed" back from 192.168.108.10
[Jul 1 17:04:12] -- Got SIP response 405 "Method Not Allowed" back from 192.168.108.10

For every extension. I am unaware of any keepalive on the Asterisk side I need to turn off. Is there anything I can turn off in 3CX to make these go away?

I'm having the same issue... Is there any solution ?
