Before starting your v13 Installation you have to check the customer network and his requirements first.

You can install a v13 setup in different ways, so we will give you an overview and a best practice for your specific case.

This information applies to

  • v13

Scenarios

Decision Matrix

On the left side you can choose the needs and conditions of your customer. Then you will see which solutions are possible or recommended.

Some information to understand the conditions in the table:

Reverse Proxy
Needed if you want connect with external phones (e.g. Smartphones or HomeOffices) to your internal PBX or Application Platform. The requirements are an official domain and access to the router configuration to configure port forwardings. If you do not have a domain, you have to rent one. If you do not have access to the router, your customer must use a Cloud Solution.
Local DNS server
All applications can work with DNS Names. You have to configure some internal subdomains with the private IP addresses of your gateways
Example PBX: pbx.domanin.tld => 192.168.2.10
Example Ap Platform: ap.domanin.tld => 192.168.2.11
External DNS server
In combination with the reverse proxy you can offer some subdomains from your external domain name with the external IP or the NAT-IP of your Reverse Proxy
Example PBX: pbx.domanin.tld => 1.2.3.4
Example Ap Platform: ap.domanin.tld => 1.2.3.4

Reverse Proxy is needed

Please check on the vertical lines the starting conditions on your customer site. After that you can check on the right columns possible scenarios for your customer.

Reverse Proxy is not needed

 • no local DNS server exists ✔✔✔ X ✔✔


  • ✔✔✔ means that we recommend it
  • ✔✔ means that you can do it, and it works fine
  • means that you can do it, it works fine but you should do some local network adjustment
  • O means that you can do it, but we don't recommended it
  • X means that you should not do it, otherwise you may run into problems


Don't forget to have a look into our training books to decide how to setup the whole network:

Scenario - innovaphone Cloud

Scenario - internal DNS Server

You can use your existing DNS Server to setup your DNS names to resolv it to the correct internal IP addresses.

Example:

  • pbx.example.com => 192.168.2.10
  • apps.example.com => 192.168.2.11

Scenario - external NAT Hairpinning

If you have no internal DNS Server and your NAT router support Hairpinning you can use external DNS entries with a record to your external IP-Address.

Your internal client should resolve pbx.example.com to your public IP address of your own router. If you configure needed NAT rules to your internal IP, your router will accept the package from inside and forward it back to the internal IP from your NAT rule.

In this scenario no separate internal dns server are required and your internal client (eg. 192.168.3.5) can talk with your PBX (eg. pbx.example.com -> 1.2.3.4) with a mapping to the internal IP (eg. 192.168.3.10)

The most used NAT Rules are:

// H.323/TLS 
[from outside] tcp/1300     => [internal IP of your Reverse Proxy] 

// LDAPS
[from outside] tcp/636      => [internal IP of your Reverse Proxy] 

// HTTPS
[from outside] tcp/443      => [internal IP of your Reverse Proxy] 

// TURN
[from outside] tcp/udp/3478 => [internal IP of your Reverse Proxy]


During the install process you have to set up a temporary internal DNS first and to configure your PC and the innovaphone Gateway to use them, which provides the local addresses. Only during the install you have to distribute the internal DNS by DHCP in your router to the Clients. If everything is finished, you can turn off the local DNS.

If you have no Hardware/Software for a temporary DNS Server you can use a innovaphone Box which is described [1].

Scenario - new DNS Server with a innovaphone Box

If you decided to setup an internal DNS than you can do that as described here:

First choose Manual Installation

Than enable the DNS Server and create A Records

Afterwards it looks like that:

In the next step you should provide the IP of this box as DNS server to all of you phones. Therefore you could use your own DHCP Server.

Now you can go back to the normal installation process of the box. Therefore just ....

Scenario - use only IP addresses

You can use static IP addresses in the installations process. So no DNS is needed.

Example:

  • PBX DNS Name => 192.168.2.10
  • AP DNS Name => 192.168.2.11
