Hi Josh,
We are still with the problem of freezing phones, we tried installing a version of similar in sipxecs everything that we have in production, the only difference was that we use a switch without PoE and every phone we put your AC adapter, but still be freezing. We have BootROM 3.1.3C and Firmware 4.1.0 with a SIPxecs 4.0.2. Appreciate any help with this problem.
