Last week I setup a small client with some GXP2130 phones. Had no issues once I moved them to current firmware.
Today I tried to edit one of them because I wanted to change a button. The only change between last week and today was I updated to 14.1.5.6 on Sunday.
Instead of a xml file being generated full of P codes, there was a text file generated still containing the gs_pval_dict.txt references.
