I am currently doing TDA50 online training on PSNA website. I am not yet certified. I have a 4x16 system installed and ready to program. It is asking me to register when I start the console. Am I to understand that the phones will appear to be dead until the system is registered?
Any info on this would be greatly appreciated.

Only the first 4 extension ports will work with an un-registered system.

Thanks 94astro

You exported out of the USA a system and 16 phones and you think that PSNA is is going to certify you?Good luck with that!
