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 figure.

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)
• Define NAT for the internal phones

VoIP rule for this scenario:

Source	Destination	Service	Action
MGCP_Call_Agent Net_A	Net_A MGCP_Call_Agent	mgcp_CA or mgcp_MG or mgcp_dynamic_ports	Accept

Defining an MGCP Rule for a Call Agent in the External Network

1. Define 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 figure, these are Net_A and Net_B.

2. Define the network object for the Call Agent (MGCP_Call_Agent).
3. Configure the VoIP rule.

   To define Hide NAT (or Static NAT) for the phones in the internal network, edit the network object for Net_A.

   1. On the NAT tab, select Add Automatic Address Translation Rules.
   2. Select the Translation method (Hide or Static).
4. Install the security policy.
