 Posted: Thu Feb 18, 2016 3:09 pm Post subject: NAT server only |
 |
|
1. Brekeke Product Name and Version: SIP Server 3.5.5.2
2. Java version:8
3. OS type and the version: Windows 10
4. UA (phone), gateway or other hardware/software involved: NEC SV8100
5. Your problem:
I am new to this and I am trying to set up the SIP server to only be a NAT transversal server. Basically I want the SIP server to do the NAT but the registration and audio will come from the NEC server.

The IP phone will be behind NAT coming to the SIP Server.
SIP Server will be behind firewall with all ports needed forwarded. |

so.. IP Phone and SIP Server are located on the same private LAN behind a router?
Is NEC server running on a public IP address? |

Sorry, I will try to explain better.
I am trying to use the SIP Server to do all NAT translations for my hosted PBX.
All the IP phones will be remote behind firewalls.
The PBX (172.16.2.10) will be at my office behind my firewall (98.x.x.x).
I want to use the SIP Server to be the NAT server between the phones and the PBX. I currently have it behind my firewall with the ports 5060,5070(port the PBX uses) and 10000-29999 open to the SIP server.
When the IP phone tries to connect to the SIP Server the SIP server should do the NAT translations between the PBX and the phone. I want to use the authentication on the PBX. |

| Also, I forgot to add that the NEC system uses port 5070 to register SIP phones instead of 5060 if that makes a difference. |

Or...
IP Phone -- router1 -- INTERNET - router2 -- SIP Server -- NEC Server

Got it.
Does the NEC server need to receive phone's REGISTER?
If so, the NEC server works as a registrar.
or you can use Brekeke SIP Server as a registrar.
If so, you need to tune NEC server's settings to define Brekeke SIP Server's IP address as a SIP trunk. |

Set [Upper Registration]=on in [Configuration]->[SIP] page, and set the NEC Server's IP address at [Register Server]. You may need to specify :5070 with the IP address.
Disable Authentication for INVITE and REGISTER in the same page.
Configure the router for Port-forwaring UDP:5060 for SIP and the UDP port range for RTP. |
