title: SIP Registration on asterisk
body: <p>Remote computer with static ip trying to register on my asterisk(1.8).
  peer settings:</p>
  
  <pre><code>[remotepeer]
  type = peer
  host = dynamic
  insecure = port,invite
  context = remotepeer-Inbound
  directmedia = no
  dtmfmode = rfc2833
  callcounter = yes
  nat = no
  contactpermit=1.1.1.1/32
  permit=1.1.1.0/24
  username = remotepeer
  secret = remotepeerpass
  </code></pre>
  
  <p>When the peer is registering i got:</p>
  
  <pre><code>[Apr 13 10:15:55] WARNING[23037]: chan_sip.c:14609 parse_register_contact: Domain '1.1.1.1:5060' disallowed by contact ACL (violating IP 1.1.1.1)
  [Apr 13 10:15:55] WARNING[23037]: chan_sip.c:15394 register_verify: Registration denied because of contact ACL`
  </code></pre>
  
  <p>When I set <code>dynamic_exclude_static = no</code> the peer is registering.<br>
  I dont want to allow registration from any IP.<br>
  How to set <code>dynamic_exclude_static = yes</code> and allow the registration for peer(ip of that peer is fixed)?</p>
