Hello,
I am Belgian, 34 years old, I have more than 15 years of IT professional experience, I have been using asterisk for years for many small companies (5-20 phones), although I have never used NCH's PABX, I think it would be quite easy for me to get it running, it's all standard SIP..
I am confident I can help you get your project running, also, I have already configured SNOM phones for asterisk.
I am available almost immediately, but I would need to have some more information regarding your network (ie: use tftp provisioning to configure your phones? Are all SIP and RTP required ports opened correctly?)
Then we can test the setup together and write down some procedures for you to remember how things are done.
You can contact me on freelancer or skype or gtalk or email..
Thank you, kind regards.
