This is the homepage of SEMSi [1], the SIP Express Media Server. SEMS is a free, high performance, extensible media server for SIP (RFC3261) based VoIPi [2] services.

News
   
  New version 1.0.0-RC1 is out:
  The first release candidate for 1.0 release is now out and ready for download [3]. If you want to participate to the testing, it is recommended to use the appropriate SVN branchi [4], where all the bugfixes for 1.0.0 will be available, as soon as they are published. This version is based on the last SVN version from May 16th 2008. Please post any noticed bug to the mailing list and, if it is confirmed, to the bugzilla, so that we can keep track of it.
   
  New binrpcctrl and sipctrl control plug-ins and binary debian packages:  
  SEMS has improved very much in usability and performance by these new developments. The binrpcctrl plug-in allows SEMS to be used with ser2, improving performance a lot and giving the advanced user the full power of the SIP Express Router 2 as SIP stack (more in this post [5]). The sipctrl plug-in, on the other hand, implements a proper SIP stack [6] (yes, you heard right!) for SEMS. Binary debian packages of 0.10 [7] and trunk versions [8] are now available for testing. These make installation of SEMS a one-liner.
   
  New codecs: speex, G726 (ADPCMi [9]) and L16
  New codecs are now available: speex, G.726i [10] in 16/24/32/40 kbit/s versions and L16. Speex is a free codec from the Xiph.org foundation and has quite good quality at comparatively low bandwidth and reasonable CPU usage. Though not a specially good codec, G726 can now be found in many SIP handsets, especially at 32kbit/s replacing G711 with half the used bandwidth at very little voice quality degradation.
   
  New applications: callgen and callback 
  Again two new applications are available in SVN: A simple call generator application, and a callback application. See the doc for callgen [11], for callback [12]
   
  New applications: Prepaid and Click2Dial 
  Two new applications are available in SVN: A prepaid application, and a click2dial application, contributed by sipwise [13]. See the doc for prepaid [14], for click2dial [15]
 
  SEMS 0.10.0 released 
  SEMS 0.10.0 (final) has been released. This release brings applications, improvements and features to simplify the creation of integrated VoIP services, many useful examples for application development, eases installation and fixes some issues related to stability.
