I am looking at phones for my asterisk system and seem to have a problem. The only Power over Ethernet phones I can find that support the IEEE standard are 3com. Cisco uses its own proprietary ( and is expensive to boot ), snom has a different but equally non-IEEE method, and i'm havent found another phone that I'm confident can do the job for our office. Whats a good high quality ip phone that uses IEEE power over ethernet -- or is there a problem with IEEE power over ethernet??

[Asterisk-Users] IP Phone with Standard Power Ethernet
Grandtream perhaps? http://www.grandstream.com/y-gxp2000.htm Got one just yesterday for testing. Not too impressed with the handsfree voice quality but everything else is pretty spot on. chris gamble wrote:>I am looking at phones for my asterisk system and seem to have a problem. >The only Power over Ethernet phones I can find that support the IEEE >standard are 3com.

We are quite happy with the phones. Tom

Yes, That none follows the standar. What voltage do you want? I can show you systems that carries from 5 to 48 V without any problem. So as in RS232 the market is the one that is going to decide were to go.

After IEEE finally released 802.3af snom supports all three modes in the 320/360 models: http://www.snom.com/whitepapers/faq-05-03-16-da.pdf (snom 320 = snom 360).

Half of my 7960G phones work with standard POE, the other half work with the special rewiring. -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com]On Behalf Of Kevin P.

I have users with 7960G phones (icon buttons) that did not work without making cross-over patch cables from our PoE injectors. _______________________________________________ Asterisk-Users mailing list Asterisk-Users@lists.digium.com http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Interesting part is that I have none G and it worked with 3af On 7/12/05, Kevin P. Fleming <kpfleming@digium.com> wrote:> Michael J.
