Configuring DMA for H323 Integration with VCS
On the DMA system, you need to configure an External Gatekeeper for VCS. This allows the
DMA system to route and receive H323 calls to devices registered to VCS.
Perform the following tasks:
• Task 1: Configuring an External Gatekeeper
• Task 2: Setting up a Dial Rule
Task 1: Configuring an External Gatekeeper
The following steps will configure the DMA System with an H.323 gatekeeper neighbor
relationship with VCS.
To configure an external gatekeeper:
1 Log into the DMA System.
2 Navigate to Network > External Gatekeeper.
3 In the Actions menu, click Add.
4 Click on the External Gatekeeper tab.
a Type a name and description for the SIP Peer.
b Ensure that the Enabled check box is selected.
c In the Address field, type the IP Address or DNS-resolvable name of the primary VCS
node.
d In the RAS Port field, enter the H323 Neighbor port to use. The default port is 1719.
e (Optional) In the Prefix Range field, enter the prefix associated with the VCS. If this
prefix should be stripped prior to sending a Location Request to VCS, select the Strip
prefix check box.
Associating a prefix with VCS depends on how you have set up dial plans and rules within
your DMA system. For detailed information, see the Polycom DMA System Operations
Guide.
Note: Prefix Range and Redundant Integrations
For redundant integrations, do not configure a Prefix Range directly on the DMA External
Gatekeeper.
