We are seeking the highest level VOIP, SIP, WebRTC, Asterisk Expert. Only the best please apply. Price is no issue if you are the best. We have an immediate voice quality problem with our Asterisk PHP cloud-based software. Our current problem is as follows: Based in Tokyo Japan. We connect to KDDI via our voip service through our data center. 1) We have been running our software for several years and generally the voice quality is acceptable although not perfect. 2) However we recently made two (2) installations and those same (2) installations have proven to be a disaster. The both have the same exact problem. 1) During at approximately the same time of day, various customers talking to customer sales agents cannot hear the agent. The result is the customer hangs up. 2) We have had various incidents every single day and cannot understand the reason. 3) No packet losses are being seen here. 4) Recently tested a codec called OPUS which helped a little but still causes repeated problems which are slightly different but in less frequency meaning the root problem is still there. 5) With OPUS we now have agent or customer or both not being able to hear each other. Again with less frequency but it is still a major issue. We need a high level problem solver and expert to help us identify the root cause and solve this issue quickly. We need you to start today until the job is accomplished. To apply, please write this in your application so I can ensure I do not have to read auto-response applications. ================================= Mr. Burns, I am highly qualified to help you fix your VOIP problem. I am available to start immediately. I am willing to take a paid test to verify my qualifications. Once you apply, my staff members Karen and or Cheza will immediately respond to you and get you started. Thank you.
