I cannot register Device

• Make sure settings are correct (server IP/username/password)
  • Try to register with empty password (Portech device had this issue - did not wanted to register with simplest password).
• Make sure UDP ports 4569, 5060, 10000-20000 are open. You can use command "iptables -F" to disable firewall temporary.
• In file /etc/asterisk/sip.conf enter correct IP for value bindaddr, correct IP = IP to which your devices are registering. Restart Asterisk
• In file /etc/asterisk/sip.conf enter correct IP for value: realm=xxx.xxx.xx.xxx ;your Asterisk IP. Restart Asterisk

• Check Asterisk CLI when trying to register with command sip debug or iax2 debug.
  • If no output at all - ports are closed
  • If some output - follow error messages, e.g. SIP 2.0/404 Not found or similar.
  • Registration from 'SOME DEVICE' failed for 'IP' - Not a local domain
  • Unable to find key 'XXX' in family 'SIP/Registry'
  • Registration from 'sip:XXX@23.45.67.89' failed for '34.56.67.89' - No matching peer found
  • Peer is trying to register, but not configured as host=dynamic

DEBUG[1534]: chan_sip.c:26128 handle_request_do: Invalid SIP message - rejected , no callid, len 405

With core set debug 4 if such error message is visible, go to /etc/asterisk/sip.conf and change

;pedantic=no 

to

pedantic=no

reload Asterisk
