[asterisk-users] How to disable authorization during Incoming calls to asterisk

[Dmitry]

Hi, List

My SIP provider requires no authorization in incoming calls to my asterisk 11.1.0 box.

I was sure previously that "insecure=invite,port" disabled authorization request during incoming calls to asterisk.
But today I tried to connect to a provider (which has MERA MVTS) but could not disable auth requests in incoming calls from this provider with this option (insecure=invite,port).

I solved the problem allowing guests in the general section of sip.conf but I am sure it is not the best solution (it impose a certain security risk - I used the IPTABLES to protect me).

I do not want to allow any unwanted guests to my box.

So How can I make this option work for disabling auth requests (I mean "insecure=invite,port") without allowing guests?


Here is my peer configuration:
[73512123555]
directmedia=no
type=peer
host=my_provider_host
secret=password
username=2123555    
fromuser=73512123555    
insecure=port,invite
context=default
disallow=all
allow=alaw
allow=ulaw
qualify=yes
qualifyfreq=60
nat=force_rport,comedia
deny=0.0.0.0/0.0.0.0
permit=my_provider_host/255.255.255.252
