Dave,
I can confirm this from experience on a solid system. Using exact same switch (found it at a really good price) with 30 of Aastra 53i and 3 of Aastra 57i CT and did try turning all phones at the same time with no problems. I never even tried it's webmanagement to do settings. Works beautifully. It is noisy a bit but it's in a cold room in this situation anyways so no problem. The only problem in my setup is a linksys 54Gxxx series linksys router with DD-WRT that requires lots of reboots. I might chnage firmware to tomate anytime. -Bruce > Date: Thu, 10 Dec 2009 18:00:24 -0500 > From: [email protected] > To: [email protected] > Subject: Re: [on-asterisk] POE capacity planning > > Lloyd, > > Thanks for the quick response.
