Separate Contexts in EVB (company a, company b)

Hi,
I've got an evb server running at my home and serving several family members around the country. I was just asked to set up some extensions for several military personnel who are about to be deployed overseas to help them communicate with their families in the states.

I see on page 120 of the Asterisk (bible) where [contexts] can be used to segregate extensions. I am afraid to add a context to the conf files for fear that it will corrupt the evb tables. Is it safe to add a context by editing the files?

Also, there may be a term in evb gui that translates to [context]. I thought about "groups" possibly being the equivalent. If there is a gui way to add a context, I'd rather do it that way.

Thanks,
Tom WA4FYN

Custom Contexts

There is a user contributed module called custom-contexts in the module admin area of FreePBX. I think it may be what you are looking for.
