MGCP Rules for a Call Agent in the External Network

An MGCP topology with a Call Agent in the external network is shown in the image. You can configure Hide or Static NAT for the phones in the internal network.

In this image, the IP phones use a Call Agent on the external side of the gateway. This topology enables the a Call Agent that is maintained by another organization. It is possible to configure Hide NAT, Static NAT or no-NAT for the phones on the internal side of the gateway.

This procedure shows how to:

• Allow bidirectional calls between the MGCP phones in the internal network (Net_A) and phones in an external network (Net_B)
• Configure NAT for the internal phones

VoIP rule for this scenario:

1. Configure the Network Objects (nodes or networks) for IP phones managed by the MGCP Call Agent and their calls, subject to gateway inspection.

   For the example in the image, these are Net_A and Net_B.

2. Configure the Network Object for the Call Agent (MGCP_Call_Agent).
3. Configure the VoIP rule.
4. Configure Hide NAT or Static NAT for the phones in the internal network. Do this by editing the Network Object. See Setting up your network for Network Address Translation.
5. Install Policy.
