Hello Everyone. I have a 200 background, but have been installing 5000's for a number of years. I know unlike the 200 and MCD, the 5000 really isn't designed as a multi-tenant system. However, the 5000 is very flexible and I know we create work arounds often that aren't in the manual. I have a customer that has two distinct businesses and they are running both off of the 5000. For all intents and purposes I have setup the two companies with totally distinct CRA's, hunt groups etc. For security purposes due to the nature of the business they want to block a company's extensions from dialing the other. In this case 100's from calling 200's and vise versa. From my research I see online that most techs say this is impossible, but I was wondering if anyone had any thoughts on this. I would think this mechanism would be possible somewhere in programming and if it was this system could really be used for multi tenants as there are other work arounds for afterhours forwarding etc. Thanks.
