I have a customer that is opening a second office. Their main office has an XTS and they have plenty of spare 3015 phones. The new office isn't large enough to justify an MBX. I know that FP4 is supposed to support these phones on the SBX, but does anyone know if there is any level of support for them using 3.5?

Nope, nothing that I know about. You could try plugging one in and see what blows up. You sure an MBX won't price out pretty close?

We never got into xts stuff but I know when putting an sbx into a place the xts phone came up and functioned in the system..not sure if the flex button support was there though. Grab one of their spares and check it out?

I can test it myself at the shop. I was just being lazy. Thanks for the feedback, guys.

sniff, sniff, what is that Burning smell... :nono:

ahh, go for it.
