> Unwanted sip INVITES to my asterisk 13 go to the default context [default] where I do just Hangup. Asterisk then sends Trying and Decline, but asterisk also temporarily opens rtp ports. As a consequence, if I get N unwanted invites within a short time and I have less than 2N ports available, then for a short time all ports will be blocked, so that the next legitimate invite will get rejected.
> Is there a way around this? I may have misunderstood parts of this process; if so please correct me.
