Then please, contact us by emailing [Click Here to Email Your Resumé]. Be sure to note the position title that you are applying for. We asked all of our employees what they thought we should mention in our job postings. Here’s some of what they had to say: “This company would be a hot commodity in Silicon Valley, but having an opportunity to work for a company like this in Orlando is rare and a huge thing for folks who don't want to have to move out of state.” “I applied for a job here, but definitely got more than I bargained for, I found a place I can call home.” “The item that really hooked me in my job interview is the health benefits. That's a huge difference in Voxeo compared to other firms.” “One of the great points about working at Voxeo is the opportunity to work and learn directly with the company's top engineers and executives.” “Corporate culture is one of the perks that has kept us from being a ‘turn and burn’ company … a large factor in our hiring process is a good culture fit, we would be remiss if we didn't stress the fact that we are looking for cool people to work with.” “I think you should say that Voxeo provides all of the tools that allow you to perform the challenging work, including telephone, laptop and the software you need to excel at any position.” “To a lot of people in IT right now, the ‘MacBook Pro’ has become the ‘hot’ laptop to have and most people will never dream of getting one because they are stuck in a space where all they will ever see are Dell laptops of various vintages.” “The great thing here is the opportunity to learn. The chance to increase your skill set exponentially in a cutting edge field and to feel truly needed and satisfied at the end of the day. Hard to quantify that sort of job experience but it is invaluable.” “I think a key point that we are trying to capture is that everyone at Voxeo works hard but we love what are working on. I think if there is some way to put down that the entire company loves what they are doing and you don’t have dead wood around is a nice thing.” “Speaking as a relative Voxeonoob, the office was a definite selling point in coming here. The view and top-floor-prestige aside, you can't understate the importance of clean bathrooms.” “We definitely have a fun and fabulous group of people.” “Everyone that works here has such a great personality and makes you feel right at home. The employees at Voxeo are accountable and extremely intellectual individuals, but they also know how to enjoy the day and laugh at the lighter side of things.” “I think the 'can do' culture should be in there, every employee is empowered to help the customer and to create a better solution.” “The fact that the company and some of the people are Silicon Valley transplants has a certain appeal. We should consider mentioning that.” “For me, the best part about working at Voxeo is our team family, and the culture of voxeo. We are intensely technical, and we work very hard, and we don't take it all too seriously.” “I think Voxeo is a rarity for the Florida market. Opportunities to work with a successful, high-tech, industry-leading company are few and far between in this area.” “One of the most attractive benefits for many people is our 100% company paid health insurance. That benefit alone can be the deal breaker for a potential employee. I would put that at the top of the benefits list.” “One of the best things about being a Voxeon is that you have access to the highest level of management in an open and laid back setting. Often times people care more about who they work worth and enjoying coming to work each day then pay, benefits, etc.” “I like the ‘Teach a man to fish’ reference. I would find a way to emphasize that management is just as involved in the technology as the employees are.” “I think the all-hands and quarterly financial meetings are something that not all companies offer, and are seen as a benefit to many as they expose the insides of the company, show that Voxeo is very open about the state of the company, and allow the employees to participate in discussions that affect the company on the whole. “ “The fact that you (the CEO) are asking us (the employees) for input on this job posting should somehow be conveyed in there as well. And it's not just the job posting, you send out things like this all of the time, showing how much you value all of our input.”

H323 and Freeswitch
by Kinetix Tele.com Mailing Lists 13 May '08

13 May '08

Hi, I am interested in the topic of Freewitch supporting the h323 protocol. I have seen various attempts to achieve that since the beginning of the whole project. The Woomera approach is in suspended mode as I saw in the wiki. I am also aware of a separate Opal approach from Tuyan Ozipek. My technical director (Hatzistavrou Vlasis) exchanged some emails with Tuyan some time ago, but I don't know if the effort is still active. Could someone please inform me if there is an "official" (or something close to that) effort of enabling H323 support for Freeswitch, because we (as a company) are willing to participate and contribute (to the extend that we can) to such an effort. If someone has any information on the subject please respond to the mailing list. Kind Regards, Apostolos Pantsiopoulos, Kinetix Tele.com Int. R&D

Minor update: modules.conf.in for mod_lua, mod_perl
by Michael Collins 30 Apr '08

30 Apr '08

Guys, If I understand this all correctly then I believe we need to add a few lines to the modules.conf.in file: #languages/mod_lua #languages/mod_perl I added them manually (without the pound, of course) and was able to build just fine using make current. Thanks, MC

Weekly Wiki Cram Sessions proposal!
by Brian West 29 Apr '08

29 Apr '08

We are working on setting up a weekly or two time weekly hour long wiki cram session where we do documentation on the wiki about various features sets... Guess you could call it whack a mole for docs. The proposal is this: 1PM CST, Recorded session podcast for everyone to follow up with that couldn't make it. As we go along we can have everyone ask questions and we'll get answers to all the questions that can then be input into the wiki by people asking the questions and filling in the holes in the documentation. I feel that doing this is key. If you think this is a good idea please let me know... What days do you propose we do these calls on? You can also call me at the address below or via freenum at 1000*543 (its in the default config) The conferences would be held via SIP or PSTN http://conference.freeswitch.org EVERYONE is welcome even if you're not a developer because everyone can help out in one way or another and we welcome it. Brian West sip:brian@freeswitch.org PS: the time is not set in stone but anything close to that would be good.

BACKGROUND_JOB event
by Juan Jose Comellas 29 Apr '08

29 Apr '08

Whenever a call to a command is made using bgapi, a BACKGROUND_JOB event is sent by FreeSWITCH when the command is completed. A BACKGROUND_JOB event looks like this: -------------- cut -------------- Content-Length: 614 Content-Type: text/event-plain Job-UUID: d19f2410-1548-11dd-9eeb-0d886880e312 Job-Command: originate Job-Command-Arg: sofia/default/user2.comellas%40192.168.1.40%3A5061%202001 Event-Name: BACKGROUND_JOB Core-UUID: f17f3284-1543-11dd-9eeb-0d886880e312 FreeSWITCH-Hostname: comellas FreeSWITCH-IPv4: 192.168.1.38 FreeSWITCH-IPv6: 127.0.0.1 Event-Date-Local: 2008-04-28%2014%3A30%3A47 Event-Date-GMT: Mon,%2028%20Apr%202008%2017%3A30%3A47%20GMT Event-Date-timestamp: 1209403847575107 Event-Calling-File: mod_event_socket.c Event-Calling-Function: api_exec Event-Calling-Line-Number: 602 Content-Length: 41 +OK d19f45e4-1548-11dd-9eeb-0d886880e312 -------------- cut -------------- >From what MikeJ told me over IRC, the body of a BACKGROUND_JOB message is actually a serialized event containing the response to the original command. The problem is that the content-type of the message is the same as that used by any normal event. This makes it difficult to have a generic parser, because we have to analyze the body of the message to determine whether we are dealing with a normal event or a BACKGROUND_JOB. The other problem I see is that the body containing the serialized event does not have a content-type of its own. An example of a message with the above mentioned problems addressed could look like this: -------------- cut -------------- Content-Length: 643 Content-Type: text/background-response-wrapper-plain Job-UUID: d19f2410-1548-11dd-9eeb-0d886880e312 Job-Command: originate Job-Command-Arg: sofia/default/user2.comellas%40192.168.1.40%3A5061%202001 Event-Name: BACKGROUND_JOB Core-UUID: f17f3284-1543-11dd-9eeb-0d886880e312 FreeSWITCH-Hostname: comellas FreeSWITCH-IPv4: 192.168.1.38 FreeSWITCH-IPv6: 127.0.0.1 Event-Date-Local: 2008-04-28%2014%3A30%3A47 Event-Date-GMT: Mon,%2028%20Apr%202008%2017%3A30%3A47%20GMT Event-Date-timestamp: 1209403847575107 Event-Calling-File: mod_event_socket.c Event-Calling-Function: api_exec Event-Calling-Line-Number: 602 Content-Type: api/background-response Content-Length: 41 +OK d19f45e4-1548-11dd-9eeb-0d886880e312 -------------- cut -------------- What do you think? Is a change similar to what I propose feasible?
