H.248 Configuration

The simplest approach to configuring H.248 is to POST only attributes for which we want non-default values. The structure of the H.248 JSON object can be queried by getting the default values, explained later on on this page.


H.248 Stack addition

This example uses default values mostly, but for some attributes, we want specific values:

 POST /configurations/{NewCFG}/h248_stacks {
 "***meta***" : {
   "version" : "2.9.10"
 },
 "advanced_parameters" : {
   "serialize_null_context_commands" : true
 },
 "enabled" : true,
 "naps" : [
   "NAP_TDM",
   "RTP_NAP"
 ],
 "timers" : {
   "local_response_timer" : "4 seconds"
 },
 "transport_protocol" : {
   "ip_interface" : "TB0999999.SIG",
   "public_ip_address" : "10.1.0.254",
   "use_ip_interface" : true
 }
 }

Here it is assumed that the configuration NewCfg is already existing. TB0999999.SIG is the IP interface name to use for the H.248 signalling trafic. This name must be globally unique, and therefore the Unit serial number must be prepended to the IP interface name.

 ip_interface = Unit.IpInterfaceName

For example, here the ip_interface name is TB0999999.SIG

Getting the default values

To add a H.248 to a new configuration, it might be helpful to get the default values first. This can be done with a GET with using new as element name under the h248_stacks collection. The attribute values from the returned JSON object can then be modified before submitting the new element using the POST method.
