Initial build of source on VS 2008
by Chuck Tharp 13 Mar '09

13 Mar '09

Hello, I'm new to FS and trying to build from the source tarball using VS 2008 Express on Windows Vista. Most of the FreeSwitch solution builds successfully, except for some of the sofia support modules. There are many errors, which leads me to believe that I have a missing compiler switch or some other setting. I started by opening the solution file Freeswitch.express.2008.sln. The first few errors are related to the MSG_HEADER_CLASS macro, being called from the sip_basic.c file: ..\..\sofia-sip\libsofia-sip-ua\sip\sip_basic.c(121) : error C2065: 'sip_request_hash' : undeclared identifier ..\..\sofia-sip\libsofia-sip-ua\sip\sip_basic.c(121) : error C2099: initializer is not a constant ..\..\sofia-sip\libsofia-sip-ua\sip\sip_basic.c(121) : error C2065: 'sip_request_d' : undeclared identifier ..\..\sofia-sip\libsofia-sip-ua\sip\sip_basic.c(121) : error C2099: initializer is not a constant ..\..\sofia-sip\libsofia-sip-ua\sip\sip_basic.c(121) : error C2065: 'sip_request_e' : undeclared identifier ..\..\sofia-sip\libsofia-sip-ua\sip\sip_basic.c(121) : error C2099: initializer is not a constant There are many other errors from different source files, but I would guess that they are all related to some setting that I am missing. Thanks, and sorry for the newbie question. Chuck

iptables and traffic control/shaping
by Frank ＠ Impact 12 Mar '09

12 Mar '09

Can anyone point me to any freelancers to do some work on traffic shaping on our linux firewall so we can get our FS voip traffic to flow properly and not compete with our email/web traffic? I have been banging my head and have followed all the details I can find on the FS wiki on this (and about every other web page how to I can find). Still I cannot seem to get it done correctly. Thanks

Does anybody recognize similar things?

12 Mar '09

Dial into a conference, heard announcement 'you are currently the only person in this conference' blah blah Now, in FS console, type conference <conf_name> kick all FS cored immediately. Is that the 'kick all' command shouldn't be used in this way?

C API session and channels questions]
by Chris Danielson 11 Mar '09

11 Mar '09

**this is a repost from the freeswitch-users group. Just wanted to work it out in the dev group. Hello Guys, I have a question regarding how I can do the following within the FS C API. What API can I use to list the current channels and sessions? What I have already in place is a generic FS module capable of serializing any sort of C data and storing it onto another device or caching server. I then have the ability to deserialize and operate on these generic objects already in my module. What I anticipate doing is finding a path to load up the FreeSWITCH (session and channel) objects and deserialize them into a freshly started FreeSWITCH instance. Any ideas on what switch_core_session.c methods, etc. I should use and any pitfalls? My primary focus for my company is conference calling, but I'd like to make this a means to work with everything that I possibly can. As soon as I get my basic testing and instances working I'll offer up the code to bkw, mikej and anthm for review. As-is, I'm not even sure if what I'm asking is even feasible, but I think having a module like this would be a good start to fill my needs and perhaps those of the community. So again, my two questions are as follows: 1) What API can I use to enumerate through the current channels and sessions initialized and running in memory? (I'm looking to clone and serialize them and store them on a separate server). 2) Any helper methods or ways that I can re-construct the channels and sessions into memory on a freshly started instance of FreeSWITCH? Kind Regards, Chris Danielson (aka. danchris)

Why does Freeswitch send Bye to sipp(uac and uas) when doing performance test?
by congxin zhao 10 Mar '09

10 Mar '09

Hi, I use sipp to performance test on freeswitch. The test environment is as following, sipp(uac 10.51.50.5 ) <->(10.51.50.4) freeswitch(10.51.51.4) <-> sipp(uas10.51.51.5 ) But when the new call rate reaches 150 new call per second, after a little while the sipp uas shows the following error. Is there something wrong with my test case? In what environment the freeswitch will send Bye to sipp(uac and uas) ?

CCXML/VXML module
by jonathan augenstine 06 Mar '09

06 Mar '09

I have a project that has a requirement for CCXML/VXML. I know this topic has popped up periodically on this list. My first question is, does anyone know of any development going on in this area on Freeswitch? I am considering writing a CCXML/VXML module, but I do not want to reinvent the wheel. If there is no current development going on, then I have some additional questions. I am looking at developing a module. I am familiar with the architecture of Freeswitch, but have not been in the core code a lot. I was considering using the XML-RPC module as a template for a CCMXL/VXML module, and I was considering using expat for XML parsing. Any comments or thoughts? Jonathan

Is there an Opp for FS here in the future?
by EdPimentl 05 Mar '09

05 Mar '09

FYI ------- by I lazaar ..Feb 27, 2009 Back in October of 2007 I authored a column for *Business Communications Review* that looked at Microsoft's entry into the VOIP market and asked whether Microsoft had entered the market after most enterprise organizations had already moved forward with alternate vendors for their VOIP plans, meaning Microsoft was too late to gain significant VOIP market share. At the time of writing, Nemertes Research indicated that 99% of organizations we had interviewed that year had already selected a VOIP vendor and were moving forward with at least a limited pilot, meaning that for Microsoft to succeed in the VOIP arena, it would have to convince potential customers to call a halt to existing plans and switch to Microsoft's Office Communications Server as a VOIP platform. Microsoft made this pitch by promising that it could cut the cost of VOIP in half when compared to its competitors. The customers for the most part didn't listen. The overwhelming majority of participants in our 2008 research interviews said that the only impact of Microsoft's entry into the VOIP space was to pay more attention to the ability to integrate their existing or planned voice systems with the Microsoft Office Communications server and client, enabling features such as "click-to-call" and presence awareness for desktop and Windows Mobile users. Now, about a year and a half later, Microsoft is stepping up its game with the release of OCS Release 2, adding a number of VOIP related features including single-number reachability and dial-in audio conferencing. Perhaps most importantly, OCS R2 adds support for SIP trunking; already Microsoft has announced a number of partnerships with service providers to bring SIP trunks to OCS installations. So with R2 is Microsoft back in the VOIP game? Not yet. Microsoft still faces some of the same issues we heard about in 2007. There's still no good option for remote site survivability nor is there an E-911 capability just yet. Integrating Microsoft into existing voice systems will typically require a mediation server (or multiple servers). Choices for stand-alone desktop phones are limited and most IT architects still don't trust software-based phones running on Windows as their primary means of communication. But maybe we're asking the wrong question? Sure, Microsoft is happy to offer OCS as a phone system replacement to those whose requirements fit Microsoft's capabilities. But perhaps more importantly, OCS is the trojan horse. Today, it offers desktop and mobile device control over communications services, Microsoft's and partners, along with a robust set of collaboration features such as instant messaging, persistent chat, audio, video, and web conferencing, and so on. It integrates presence into the full suite of Microsoft office products including Exchange/Outlook and Office. Web-based clients enable non-Windows users to become part of the Microsoft eco-system. And maybe, just maybe, as OCS's phone feature list grows, and as OCS deployments grow, perhaps with R3 Microsoft will begin to convince a growing number of its customers that they really don't need that old IP-PBX anymore when employees are already using OCS to make the majority of their calls. As we conduct our 2009 round of interviews we're continuing to gather data on the role of Microsoft in VOIP/UC planning. Stay tuned...
