Re: [Asterisk-Users] Linksys SRW224P POE Switch
Ok, so I tried making my own cable. I have the Linksys switch. The phone powered up, but never registered. I don't know if this could be a VLAN issue or not. When I got back to my desk, I noticed asterisk was giving off all kinds of notices and warnings. It took restarting asterisk to get the network working again. Asterisk itself was not affecting. (I'm passing some PRI channels through to a legacy box, and that was still working). But, it appeared asterisk could not communicate with the SIP and SCCP phones. I'll have to work on this more afterhours. On 6/14/06, Lacy Moore - Aspendora [EMAIL PROTECTED] wrote: I was just about to suggest the Powersense module that Cory mentioned.

Re: [Asterisk-Users] Linksys SRW224P POE Switch
There is an RJ45 cabling guide on the WIKI that shows how to create a reverse polarity crossover cable to power Cisco legacy PoE phones, and I can attest that it works with all the applications I have tried. Belkin/Powersense also makes an inline module for Cisco CDP that is relatively inexpensive.

The Cisco IP phones that end in 1, for instance 7941, 7961, 7971, all support 802.3af standards, and were built just for that.
