Is there defined hardware that needs to be used with trixbox Pro?
Hardware is critical. Not all servers, cards, or phones are alike (even if they say “SIP-compliant” on the box). For this reason, we have built three hardware categories. Depending on which category your deployment falls into you will receive more favorable support pricing and options. Also, consider using the trixbox Appliance, which is built specifically to run trixbox CE and trixbox Pro.
