Is it possible for POE switch to provide power to ports on NON-POE switch?
We have an HP 2920-48 port POE switch. We also have 2x HP 2920-48 port NON-POE switches. I was surprised to find today that our new VOIP phones are actually get power when plugged into the NON-POE switch?! Is this possible?? If so, are there possible issues I should consider when configured in this manner. I know we are having issues with the phones losing calls before they can be answered...wondering if related.
That's very odd. The answer to your question should very much be no, unless you have an injector of some sort between the non-POE switch and the phone. Are you sure there isn't some sort of other POE switch in the middle?

None. Phone->CAT5>Switch....no adapter or anything in between

HP 2920-48G-POE+ Switch (J9729A) and HP 2920-48G Switch (J9728A) - phone is connected to the J9728A
Then I would be concerned.
