Project : [http://http](http://http)://rubyforge.org/frs/?group\_id=7001 Homepage : [http://sipper.agnity.com](http://sipper.agnity.com) June 23, 2009 # Overview The downloads are available from Rubyforge Sipper project website for 2.0. The downlaods are in the form of platform specific gems for RH Linux, Windows and Solaris. This is so because there is a native library that is not bundled as a native extension to leverage multi-core, multi-cpu boxes that are so prevalent in telecom labs. If your platform is not listed above then you can check out the source from SVN and build SipperMedia binary under /media/ and copy the binary to /bin. Then build the gem using “gem build sipper.gemspec” or rake task # Installation The installation is just a gem installation. “gem install SipperXXXX.gem” where the gem file is your platform gem file. If you are using an older version of SIPr you can safely uninstall older version using “gem uninstall Sipper” and also remove any Sipper installation from windows using \programFiles\Sipper\uninstall.exe Please refer to the latest Sipper book from [http://sipper.agnity.com/http://sipper.agnity.com/documents.php](http://sipper.agnity.com/http://sipper.agnity.com/documents.php) # Changes since last release 1. Feature to pause and resume the load on Linux is added. CTRL^z is the key used to pause and resume the load.[June 23 2009] 2. The default log directory for non project executables like ssmoke etc has been shifted to a temporary file 3. If Session is attached to a transport, IP and Port (created using the right Session type and IP and Port provided e.g create\_udp\_session(ip, port)) then it (the transport/ip/port tuple) is used for all purposes and never changed unless user changes IP and Port from the controller. If the session is detached (e.g create\_session() or create\_udp\_session()) then the destination is ascertained by normal SIP rules taking into account SIP URI, pre existing routes, Route headers etc and is also changed/modified as a result of SIP signaling like remote target update during the call establishment or subsequent to call establishment. [June 12 2009] 4. Changes done to simplify SIPr installation. Now SIPr is just one gem install. [June 9 2009] Note the details below. 5. For new projects after the gem install it works out of the box **.For old projects (backwards compatibility), just copy the new Rakefile in the project directory root and everything should work fine. (To get the new Rakefile, just create a blank new project and copy the Rakefile).** **-** **For running from the source directly. (Developers only), assuming no Sipper gem installed on that machine, just Rubyforge SVN checked out and also no sipper in windows ProgramFiles. .You shall need the SIPPER\_HOME env var and point to the root of your SVN check out (one dir above “sipper” or “sipper\_test”) .Also need to copy the commands in your ruby/bin or /usr/local/bin for sgen, srun, sproj and ssmoke. Take the example for sgen as reference "ruby $SIPPER\_HOME/bin/sgen “$@” .Both old and new projects should work without any change with source installation.** **- Fix for –n 1 in bulk. In new scheme if rate was 1, with RunLoad option, controller was not running. [May 24 2009]** **- Modified SDP class. Added the ability to add media attributes other than “a”. So far using add\_media\_attribute\_at() function always added a=xxx parameter. Now for all media attribute functions add/remove/get media\_attribute(s)\_at functions we have an optional third argument that takes the type of attribute, one of :m, :i, :c, :b, :k, :a. The default is :a. So in order to add a “b” attribute on the first media line (index 0) you would do - sdp.add\_media\_attribute\_at(0, “AS:12600”, :b) [May 24 2009]** **- Bug fix for #22249. Recording name now rolls over while bulk testing [May 24 2009]** **- Fix for bug #23943. Added the bin dir in the gemspec. Also included /usr/local/bin in the search path for media (for backwards compatibility). [May 11 2009]** **- If protocol compliance is set to lax then early media can even be established with non reliable provisional response. Of course only answer will work here, offer cannot be made with non-reliable provisional response anyway. [May 11 2009]** **- emit\_console is also made a controller directive now. So you can set “emit\_console true” in the controller and ALL messages will be printed. This is useful for UAS case when setting on session could be done only when first message was received and so it was not printed. [May 11 2009]** **- Simplified load testing without any modification to the test or controller. In order to run the test in bulk mode, all you need is a new configuration option :RunLoad set to true, or alternatively have a –l (minus lowercase L) flag passed on to srun. You can optionally pass –b or –n option to srun in addition to –l as before to override the number of calls or call rate, otherwise the defaults are picked from configuration from :NumCalls and :CallRate [April 13 2009]** **- Fixed WaitForSignaling effect as the test was not exiting. [Mar 22 2009]** **- SIPr media API rehash to have simplified APIs for all media access. Also included the past work for voice activity detection. [Mar 17 2009]** **- Added ability to exit from srun (from within the controller code) using SIP::Locator[:Sipper].sipper\_exit will also need to require ‘util/locator’ in controller. This is in addition to -rf or run for option from srun commandline. [Mar 17 2009]** **- Added the ability to print messages as the test progresss. Using session.emit\_console = true for a particular session. [Mar 17 2009]** **- Added the ability to alter the SDP body (session-lines, owner-version, media-lines and media-attributes)after creating the offer or answer.[Mar 17 2009]** **- Feature #24328. The ACK to non failure response is now delivered to controller, such that it can clean up and perhaps more importantly finish the test in some cases. [Mar 15 2009]** **- Fix for bug #24327, not sending cnonce when no qop in challenge, also the ability to not send qop in the challenge. [Mar 12 2009]** **- Fix for bug #24439, ProxyController::create\_proxy\_request doesn’t handle Record-Route correctly. [Mar 12 2009]** **- Network Asserted Identity implemented as per RFC 3325. [Jan 05 2009]** **- Support for integrated webserver provided. Now the same controller can also act like Webserver and handle HTTP and SIP requests. The association of SIP and HTTP Sessions is automatic and seamless. A pattern similar to SIP handling has been used to have same look and feel in controllers. [Dec 24 2008]** **- Digest Server authentication added in SIPr. Earlier we just had Digest client support. Now users can also challenge a request from a UAS. Two levels of API added one purely directive based and other gives complete control over challenge creation and response matching. [Dec 21 2008]** **- PIDF generator implemented as per RFC 3863 and example test case as per RFC 3856 added.** **pidfdata = XmlDoc::PidfTuple.new(“open”, “sip:removed\_email\_address@domain.invalid”, “0.2”, “Welcome to SIPr World !!”)** **r.content = session.create\_pidf\_doc(“sip:removed\_email\_address@domain.invalid”,pidfdata, “Registration done !!”).to\_s** **[Dec 19 2008]** **1. SIP Registration Event - API to generate reginfo doc and example test case as per RFC 3680.** **r.content= session.create\_reginfo\_doc(‘sip:removed\_email\_address@domain.invalid’,0).to\_s** **[Dec 18 2008]** **1. Private header extensions implemented as per RFC 3455 [Dec 11 2008]** **2. Privacy mechanism implemented as per RFC 3323, 3325 & 4244. One can apply the complete privacy service by calling a simple API called “apply\_privacy()” in SIPr b2bua\_controller.** **request = apply\_privacy(request)** **[Dec 11 2008]** **1. Sipper Load balancer - a SIP UDP load balancer to scale up the Sipper load, implemented as external process [Dec 10 2008]** **2. Included support for TCP transport according to RFC 3261 [Dec 03 2008]** **3. Improved interface for verify\_call\_flow(), the direction is now optional [Dec 03 2008]** **[released as patch - 1.1.3.2 Sipper-1.1.3.2.gem Nov 11]** **1. Handling of new headers for PUBLISH method and example test case as per RFC-3903. [Nov 13 2008]** **2. Fix to speed up the recvfrom\_nonblock read from UDP socket on Windows platform. [Nov 11 2008]** **3. Service-Route Header implemented as Address Type header. Example test case as per RFC-3608 added. [Nov 11 2008]** **4. Helper methods for Replaces header creation and finding session based on Replaces Header value. Rejection of improper Request with replaces header as per RFC-3891 in strict mode. To create a replaces header for a session and find the session from the replaces header.** **request.replaces = session1.create\_replaces\_header** **session1 = session2.find\_session\_from\_replaces** **[Nov 10 2008]** **1. Session recorder file name fix to read the files in order of creation in platform independent way.[Nov 9 2008]** **2. Support for PATH Header (RFC-3327) [Nov 9 2008]** **3. Support for Media keepalive to keep NAT binding open for media channel when SDP negotiated to Inactive or RecvOnly state. [Nov 7 2008]** **4. NAT discovery and traversal code based on config and/or controller directive or session config, helper method for REGISTER [Nov 7 2008]** **5. Enhanced HTTP API to support - Basic authentication, PUT request, addition of custom header, arbitrary body [Nov 3 2008]** **[released as patch - 1.1.3.1 Sipper-1.1.3.gem Oct 21]** **1. Fix to add an empty header (without value) to a SIP message [Oct 21 2008]** ---
