• Hi Motty,

  Please, set Verbose to 3 and Debug to 3 At Asterisk CLI. Then “sip set debug on”.

  Now try to register again. At last, ” sip de debug off”.

  Examine tour console or full log file to find some clue ir send me back some trace.

  Cheers.

• Hello Victor,

  I did set debug on, but I don’t see any errors. I did tcpdump, client is trying to register: here is the header of a udp packet

  User Datagram Protocol, Src Port: 55300, Dst Port: 5060

  Session Initiation Protocol (REGISTER)

  Request-Line: REGISTER sip:pbx.mydomain.com:5060 SIP/2.0

  nat=yes

  Is NAT value set to yes OK? Servers is on public IP, client is on private network.

  Thanks, Motty

  any ideas?

• Ok.

  Please, note that 192.168.1.37 (I suspect) is the internal LAN address Of the Polycom hardphone. If this is true, then you have NAT issues.

  The REGISTER message are received by your PBX, but when respond, Asterisk send the next SIP message to the IP informed by the phone, that is the internal LAN address. The messages do not reach back to the hardphone.

  You need to setup a STUN server in the Polycom hardphone settings. Please, check the manual. Search in Google some public STUN server to put in the settings.

  Last, the idea behind the “sip set debug” command was view the complete SIP
  messages conversation, not search for an error.

  On NAT escenarios, remember:

  * The NATed phones need to know the public IP of the NATing router. Either by manual setting or by STUN protocol.

  * Reduce the time between REGISTERs attempt, if the client have a dynamic IP connection.

  * Use the “localnet” SIP settings in Asterisk, so the PBX can distingish what Network need contacted via NAT and what not.

  Cheers.

• Thank you for your help! CentOS 7 firewall was enable.

  systemctl stop firewalld

  issue fixed.

  Thanks,
