    Thank you for taking the time to review my profile! If you are looking for a consultant whom lives, breathes, and sleeps Vicidial, you found him. Ask me just about anything. I’m a walking talking Vicidial manual! I stand by the software, and I firmly believe that it is an excellent, if not the best choice for your needs with a free and open source outbound predictive dialer, or inbound call menu operations. I will guide you through your Vicidial system, or just get in there and get the job done if that’s what you need. If you are looking for assistance configuring the VICIdial API, settings up custom fields, or integrating with CRM systems, I can certainly help you with that as well. Since 2008, I have worked with Vicidial on almost a daily basis for all types of organizations from all over the world. I love working with people! So having the opportunity to work for such a wide range of organizations within a global community is an honor for me. Therefore I’m committed to going above and beyond the call of duty to ensure that my clients receive the best possible service. I had years of Customer Service and Call Center Management experience under my belt before becoming acquainted with Vicidial, so having a passion for putting the customers first while providing clear and concise answers or solutions has been a part of the way I work since early in my telecommunications career. I really enjoy opening new doors for my clients with all the great features that may not be in their Vicidial manual. Nothing puts a bigger smile on my face than exceeding my client’s expectations with additional solutions. Please feel free to reach out to me. I have plenty of references available. I hope to have the opportunity to connect with you in the future. Thank you Sincerely, Jameson S. VICIdial Expert

    Hi, I'm Bucky. I'm a consultant specializing in all manner of VoIP services. My experience is mostly on the backend, building solutions around primarily open-source VoIP technologies (Asterisk, FreeSwitch, Kamailio) and cloud provider APIs (e.g. Twilio, Telnyx, and Signalwire) with a sprinkling of proprietary Cisco and Oracle/Acme knowledge thrown in for good measure. I'm happy to handle simple stuff like account provisioning or troubleshooting call quality issues, but I'm also more than capable of taking on high-complexity projects up to full carrier environment setups. One thing that sets me apart from a lot of other freelancers is that this is not a "side-hustle" for me -- this is my full time job. I have an office and a desk phone, and am basically always within 10 steps of a PC. If you hire me for a project (whether it's a short-term endeavor or long term recurring contract), you'll get access to my contact info, and the peace of mind that you've got an on-call telecom expert for emergencies. Before I ventured into consulting, I spent a good chunk of my career working in the telecom industry for "large" competitive local exchange carriers and enterprises. I enjoyed the work but could never find the "value" in what I was doing, so I ultimately made the switch. Honestly, while it's not as profitable for me to help smaller carriers and businesses, helping the little guy and seeing the direct result is a lot more rewarding to me.

Over the years, I've developed the skills and experience necessary to succeed in any IT role. Examples of my relevant experience include leading the corporate initiative to commence delivery of managed IT services through co-located servers and virtualization, configuring ESXi, vCenter & Hyper-V servers, VPN, firewalls and VLANs for multi-tenant virtual environments, which has been successfully operated for more than 4 years from datacenters in Europe, USA and Canada. I have a strong experience with Asterisk (elastix & FreePBX), Sangoma, PSTN & SIP Trunk implementation for IP Telephony, which I have implemented on several counts for small, medium and large enterprises across local and international borders. I facilitated the deployment of SharePoint 2013 accessed by over 300 staff on Windows Server 2012 by configuring the Active Directory and Microsoft SQL Server for the SharePoint implementation project. I am also known for my resourcefulness, strong analytical, troubleshooting & problem-solving skills as well as research ability, which generate a lot of consultancy and support requests for me on and off the job. I've successfully led or been part of teams on many projects one of which is a pilot document management project for a university which set in motion their paperless operation. I am confident that I would be an excellent match for any project you have.
