H.323 Signaling Interface Settings

You can set the following parameters to define basic settings for your H.323 interface. This is where you set the IPv4 address for opening sockets, the RAS and Q.931 ports, and the maximum number of Q.931 calls that you want to allow.

This is also where you establish Annex E alternate transport. Annex E supports multiplexed call signaling over UDP so that call volume and performance are potentially enhanced. If you do not configure Annex E support, then this H.323 interface does not listen for Annex E requests.

To configure H.323 interface settings:

local-ip—Enter the IPv4 address that the H.323 interface uses when opening sockets; this is the default H.323 interface IPv4 address. You must use a valid IPv4 address. For example: 192.168.2.5. The default value is 0.0.0.0.
ras-port—Enter the number of the port on the local IPv4 address (local-ip) on which the Oracle® Enterprise Session Border Controller listens for RAS requests. We recommend that you set this parameter to its default, the well-known port 1719. The valid range is:
- Minimum—0
- Maximum—65535
  
  If you set this parameter to 0, the Oracle® Enterprise Session Border Controller uses a port assigned by the operating system.
q931-port—Enter the number for the port on the local IP address for the Q.931 call signaling port. We recommend that you leave this parameter set to its default, 1720. The valid range is:
- Minimum—0
- Maximum—65535
q931-max-calls—Enter the maximum number of concurrent Q.931 calls you want to allow. The default value is 200; however, this value should be less than the maximum number of calls you set when configuring H.323 features. The valid range is:
- Minimum—0
- Maximum—65535
  
  If the number of received Q.931 calls exceeds this number, the H.323 interface returns a busy state.
alternate-transport—Enter a list of one or more Annex E IPv4 address and port combinations for alternate transport. If you do not configure this list, then the Oracle® Enterprise Session Border Controller does not listen for incoming Annex E requests. You must enter the IPv4 address and port combination in the following format, where the two are separated by a colon: IPv4Address:Port.
