NAT and/or PAT When a network host A sends a request to another network host B, it will be expecting a reply to the request. When both network hosts reside on a Public IP Address, the exchange is direct, and simple enough. If one of the network hosts resides on a Private IP Address, however, things start to be come more complex, because the network environment is a NAT/PAT environment. If network host A is in a NAT/PAT environment, when it sends a request to network host B, it will build its request using the only IP Address it knows – its private IP Address

Some SMTP servers may be configured to allow only TLS or SSL exchange. You can achieve this using the following procedure: On the 3CX machine you will need to install the SMTP Server available as part of the IIS installation procedure. This is done from the Control Panel > Add/Remove Program > Windows Components. Under the ‘Internet Information Services’ enable the ‘Simple Mail Transfer Protocol’ checkbox.

The main reason for this is NAT. Therefore some tweaks need to be made to the 3CX Fax Service Configuration Files. IMPORTANT: VoIP Provider testing of the 3CX Fax Server was performed in March 2010 and this document was updated with the new information. The NAT changes described in this document apply for the following VoIP Providers: Inphonex, and Actiopl Some VoIP Providers do not need this setting but others will not work without it. The best thing to do is to leave the configuration unchanged and try with the default configuration files as shipped by 3CX

A caller can call a callee from either a stand alone SIP phone which is not registered to any SIP server, to a VoIP provider, or from a SIP phone registered to an IP PBX, which supports direct SIP. If a user calls “robert@voipproducts.org” from a stand alone SIP phone, the caller’s soft phone makes appropriate DNS queries to resolve the address of the SIP server responsible for SIP based VoIP calls to voipproducts.org. Once the SIP server’s IP Address is resolved, the caller’s soft phone initiates a SIP session with the SIP server responsible for the domain voipproducts.org.

This simple concept allows us to exploit the SIP Proxy Tunnel to overcome difficult situations, or to simplify a network scenario. The SIP Proxy Tunnel can be used for the following reasons: Resolve issues of NAT Traversal at both the remote and the PBX location Simplify Firewall configuration at both the remote and the PBX location Overcome difficulties with ISPs that block VoIP Traffic based on port numbers Allows VoIP-over-WiFi in some restricted locations, such as Hotel rooms “Fixes” Firewalls that cannot handle VoIP traffic correctly or which are very difficult or problematic to configure correctly, such as: Microsoft ISA Server SonicWall Typical Scenario The above diagram shows a typical scenario for implementing the SIP Proxy Tunnel in a remote location.
