Chapter1.Admin Guide


This module is a gateway for presence between SIP and XMPP.

It translates one format into another and uses xmpp, pua and presence modules to manage the transmition of presence state information.


1.2.1.OpenSIPS Modules

The following modules must be loaded before this module:

  • presence.

  • pua.

  • xmpp.

1.2.2.External Libraries or Applications

The following libraries or applications must be installed before running OpenSIPS with this module loaded:

  • libxml.

1.3.Exported Parameters


The IP address of the server.

Example1.1.Set server_address parameter

modparam("pua_xmpp", "server_address", "")

1.3.2.presence_server (str)

The the address of the presence server. If set, it will be used as outbound proxy when sending PUBLISH requests.

Example1.2.Set presence_server parameter

modparam("pua_xmpp", "presence_server", "")

1.4.Exported Functions

Functions exported to be used in configuration file.

1.4.1. pua_xmpp_notify()

Function that handles Notify messages addressed to a user from an xmpp domain. It requires filtering after method and domain in configuration file. If the function is successful, a 2xx reply must be sent.

This function can be used from REQUEST_ROUTE.

Example1.3.Notify2Xmpp usage

	if( is_method("NOTIFY") && uri=~"")
			t_reply("200", "OK");

1.4.2. pua_xmpp_req_winfo(char* request_uri, char* expires)

Function called when a Subscribe addressed to a user from a xmpp domain is received. It calls sending a Subscribe for winfo for the user, and the following Notify with dialog-info is translated into a subscription in xmpp. It also requires filtering in configuration file, after method, domain and event(only for presence).

It takes 2 parameters: request_uri and the value of Expires header field in received Subscribe.

This function can be used from REQUEST_ROUTE.

Example1.4.xmpp_send_winfo usage

	if( is_method("SUBSCRIBE"))
		if(uri=~"" && $hdr(Event)== "presence")
			pua_xmpp_req_winfo("$ruri", "$hdr(Expires)");


1.5. Filtering

Instead of "" in the example you should use the value set for the xmpp module parameter named 'gateway_domain'.

Chapter2.Developer Guide

The module provides no function to be used in other OpenSIPS modules.
