Chapter . Getting a Gateway Up and Running with H.323

To set up a functional GW with GK support, follow these steps:

  1. Set up GK and GW registration:

    GW1(config)# gateway

  2. Create the H.323 interface:

    GW1(config-if)#  h323-gateway voip  interface **under interface configuration mode

  3. Create the H.323 ID:

    GW1(config-if)#  h323-gateway voip h323-id

    This command assigns a unique H.323 ID for the device. This ID is used on the network for identification and connectivity.

  4. Manually configure GK information (optional):

    GW1(config-if)#  h323-gateway voip id (name) ipaddr IP address port

    This command manually sets up connections to other control devices (GW or GK). You may leave out this command if you need only a basic GW.

Example . Example: Gateway Interface Configuration

interface FastEthernet0/0
 ip address 5.5.5.98 255.255.255.128
h323-gateway voip interface
 h323-gateway voip id Gk-Infantry ipaddr 75.75.50.1 1719
 h323-gateway voip h323-id GW-1

Configuring SIP User Agents

Setting up SIP is extremely easy:

  1. Enable SIP.

  2. Set up alternate SIP servers (optional).

  3. Set up dial peers.

sip-ua
sip-server ipv4:75.1.1.69

or

sip-server dns:my-sip.com


Dial-peer voice 12 voip
Session target sip-server
