Introduction Configuring the Dialogic Media Gateway

Multiple Media Gateways

If you require more than one media gateway to support the number of simultaneous calls for your

application, you must take into consideration the PBX hunting type. Hunting type refers to the ordering

technique (linear, circular, most-idle, etc.) the PBX uses to present incoming calls to NetVanta UC Server

and the specific sequence (ascending or descending) that the PBX uses to send calls to NetVanta UC

Server.

When configuring multiple media gateways, it is best to do the following:

1. Configure the media gateways to assign incoming calls (from the PBX) to media gateway ports in the

direction opposite the one used by NetVanta UC Server for outgoing calls. That is, incoming calls

should be assigned beginning on the first media gateway (non-primary) in a linear, ascending fashion

across all media gateways and outgoing calls assigned beginning on the last media gateway (primary)

in a linear, descending fashion. This reduces the possibility of collisions (glare) between incoming and

outgoing calls.

2. Configure as many ports on the primary media gateway as possible. That is, if the application requires

fewer ports than the total number of ports on the media gateways (for example, the application requires

12 ports but you have enough ports to configure 16), make sure that the last media gateway (primary)

has all ports provisioned.

Supported Features

The following features are supported by the integration of NetVanta UC Server with a Dialogic media

gateway:

• Call forwarding to personal greeting

- Busy

At a minimum, you must configure the incoming calls from the PBX to terminate on a

non-primary media gateway first.
