Pbx Mantenimiento

I am in need of a freelancer with strong skills and experience in PBX maintenance. Specifically, I have a digital PBX system that requires attention. The main issues that I am experiencing are related to configuration problems, as well as the need to migrate to Freepbx and develop new applications. Ideally, the freelancer will be able to complete this work within 1-2 months, though there is some flexibility with the timeframe.

The ideal freelancer will have experience with digital PBX systems and be able to troubleshoot and solve configuration problems. Additionally, experience with Freepbx migration and application development would be highly valued.
