NAT Configuration Examples
When the network topology prevents direct connections between terminals and the server components, the streams need to be relayed using Network Address Translation (NAT).

- Prompts
  Prompts are messages that customers hear and receive in various situations, for example, they inform the customer about the position in a queue and about the service times.

NAT Locations with Trunks

NAT location can also be defined for SIP trunks (gateways). Define the location content with options Network Elements, IP range or IP Subnet.

Locations may contain both users and trunks, so it is possible to use direct RTP between agents and trunk when a local trunk exists in the user network.

In some cases, the network topology requires streams to be routed via two MRS components – for example if the user and trunk are both in different parts of the network, and both sides require NAT. In this case, the system routes the RTP stream from the user to the MRS serving the user location, from there towards the MRS serving the trunk location and finally towards the trunk. However, this kind of configuration should be used only when it is absolutely necessary since each additional MRS route point introduces some delay.
