You can do this - the best way to do this would be to create a root certificate and put that on all the PC's, phones etc. that the customer uses.

 

There is a useful article about doing this at the link below.

If you are going to use MRA then you would be best off using a decent third party CA for the Expressway E cert - this is going to be mandatory if they want to connect 7800/8800 phones via MRA as they will not support connecting to an Expressway that has a cert from a non approved provider.

You can use any CA you like as long as the certificates have the proper key usage and enhanced key usage for each product/application.
