Management Interface (MI), the old line-based text protocol interface to interact with Kamailio is going to be removed in the near future. It was declared obsolete several years ago, when we introduced the RPC interface. With upcoming version 5.0 already having the code source tree restructured, this step makes a better and slimmer foundation for next generation of releases.
The default configuration file is now shipping with jsonrpcs module and kamctl tool is using the RPC interface via jsonrpcs. The command line parameters for kamctl should be the same like for the past releases, but the output is now in jsonrpc format.
The RPC interface is implemented by the following modules:
- ctl – binary rpc protocol – with transport layers for FIFO file, unix sockets and IP sockets (both datagram and stream). It is the module used by the kamcmd tool.
- jsonrpcs – jsonrpc protocol – with transport layers for FIFO file, unix and IP sockets (datagram) and HTTP via xhttp module. It is the module used by kamctl and kamcli tools.
- xmlrpc – xmlrpc protocol – with transport layer for HTTP
If you were using mi_fifo or mi_datagram modules, then you can switch to jsonrpcs module (it offers the transports for the two mi modules). If you were using mi_xmlrpc, then you can switch to xmlrpc module.
Thanks for flying Kamailio!
