Anthony, Could you elaborate a little on what led to your selection of Sofia-SIP for SIP trunking in FreeSwitch? What did you like about Sofia-SIP? What didn't you like about the alternatives? Do you know of any online comparison of features, strengths and weaknesses, for the several SIP stack alternatives? Thanks.

This is a requirement if you're following trunk: svn update make sofia-reconf current vm-sync Please issue that command if you encounter any strange issues or crashes. This should take care of it. Thanks, Brian West sip:brian@freeswitch.org 1000*543 (freenum)

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.”

[Freeswitch-dev] 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
