Looking for someone experienced in mainly Mirta PBX or Asterisk by itself is less preferred but might be an option.. you would likely be a voice Engineer and will need to train people in use of and maintenance the PBX.
Hi mate,
I've worked with Asterisk for a long time - from design and deployment to extension module development. Also worked with some PBX derived from Asterisk. Will be happy to help with your tasks.
Cheers,
