Re: [Users] WeSIP API

Hi, yes ! :-) WeSIP implements an standard API for SIP programming which is the SipServlet API. You can find information in many sites but for your convenience I have added a SIP Servlet javadoc section (http:// www.wesip.com/mediawiki/API/index.html) as well as the API especification (http://www.wesip.com/mediawiki/API/sipservlet-1.0- fcs.pdf). I strongly recommend as well that you read the tutorial as an introduction (http://www.wesip.com/mediawiki/index.php/ Tutorial:SIP_Servlet_Programming_model) Yes indeed, you can program b2bua with it. Please have a look at the demo applications (http://www.wesip.com/mediawiki/index.php/ ApplicationsIndex). In the SIPServlet API each SIP dialog is abstracted through the SipSession Interface (http://www.wesip.com/ mediawiki/API/javax/servlet/sip/SipSession.html). A b2bua application has two dialogs which are represented by two SIPSessions. The two SipSessions are contained in an ApplicationSession which is the representation of the application itself The SipFactory interface in the SipServlet API (http://www.wesip.com/ mediawiki/API/javax/servlet/sip/SipFactory.html) offers a method to create a new leg (SIP Session 2) when an incoming INVITE arrives (SIPSession1). The method is public SipServletRequest createRequest(SipServletRequest origRequest,boolean sameCallId) which creates the two call legs with the two SIP sessions contained in the application session ApplicationSession | ______________________________ | | SIPSession 1 SIPSession 2 UAC<------------------>B2BUA SIP SERVLET<------------------> UAS Regarding NAT configuration it is supported by OpenSER itself. Read the configuration section (http://www.wesip.com/mediawiki/index.php/ Configuration), there you'll find an explanation on how you can combine OpenSER features with WeSIP. Hope it helps! Gines
