I have an Asterisk/FreePBX/A2Billing system in place that needs to be fine tuned to suit our needs. I need someone for day-to day troubleshooting, support, and security maintenance. I am looking for someone who understands how to fix problems with DTMF and international mobile calls where the recipient of the call is required to dial a number to accept the call. This person must speak English well and be available during the Eastern Standard Time hours.
