Dialog-related information such as tags, contacts, and CSeq in the SIP messages 
are handled automatically.

■

On outgoing requests, OCMS performs DNS lookups and supports NAPTR-, 
SRV-, and A-records (according to RFC 3263).

The SIP Servlet API enables data to be stored as session attributes. Session attributes 
can be used to store session specific data to be used in responses and subsequent 
requests or from a listener class. The attributes are stored and accessed through setters 
and getters directly on the session object. The session can be either a SipSession or a 
SipApplicationSession

. An attribute can only be retrieved from the same session 

it was set. For example:

session.setAttribute("key", "value");

session.getAttribute("key"); // Will return "value"

session.removeAttribute("key");

Although the session attributes can store any object, the attributes and their keys must 
be serializable for applications that are distributable (for High Availability). Use the 
getAttributeNames

 method to retrieve all of the set attributes. For example:

Enumeration attributes = session.getAttributeNames();

String attributeName = null;

while (attributes.hasMoreElements())

{

  attributeName = (String) attributes.nextElement();

  Object attribute = session.getAttribute(attributeName);

  log (attribute.toString());

}

A servlet can be configured by adding parameters to the <servlet> section in the SIP 
Servlet application descriptor (sip.xml). The servlet can then access these parameters 
through the getInitParameter method. 

 illustrates how to configure 

the response code.

package com.mydomain.test;

import javax.servlet.sip.SipServlet;

import javax.servlet.sip.SipServletRequest;

import javax.servlet.sip.SipServletResponse;

import java.io.IOException;

public class MySipServlet extends SipServlet

{

  protected void doRequest(SipServletRequest req) throws IOException 

  { 

    int responseCode = Integer.parseInt(getInitParameter("responseCode"));

    SipServletResponse resp = req.createResponse(responseCode);

    resp.send();

  }

}
