similar to: Calls Dropping w/ Cisco 7960 Phones

We are connecting the GXP2000 to a Cisco POE switch 3650, it the default mode at 15.4 for each phone the phones power up but we can only have 24 on a 48 port switch, when we adjust the setting to 7000 (which is what we calculate the phone to use) they don't power up ... we tried all the power settings from 7000 up to 154000 but it only powers up at 15.4, we should be able to get almost 48

I am hoping that someone has had better luck with this than I have. I would like to connect Cisco 7940s and 7960s to the Netgear FS116P, and take advantage of its POE. I know that the Cisco phones use Cisco's "pre-standard" POE implementation, but as I understand it the difference is really only two pins. I bought a bunch of PowerDsine inline power adapters which supposedly change

I'm having problem powering Cisco phone's (7940 and 7905) on Linksys SRW224P switch (with PoE functionality). I have tested three phone's, one is working (7905) and two aren't (7905 and 7940). I have plugged all three phones on same switch port with same cable! Do I need to change anything in phone configuration? Is there something wrong with Linksys switch? How can I troubleshoot

Just attended the Cisco Networkers conference and sat through a presentation addressing in part the Cisco IP phones. All was presented openly without the need for disclosures, etc. The following is simply an FYI from the presentation, FWIW. Existing IP Phones (7905/7912/7940/7960): Transport: UDP Call Signalling: rfc2833 Security: Digest Auth Feature parity to SCCP: None Sip Enhanced

I've tried to use a Cisco power injector to supply power over Ethernet to a GXP2000 phone without success. Although when I plugged these phone to a PoE capable Cisco Switch it worked without a problem! Knowing that all these three equipments implement IEEE 802.3af protocol, why doesn't it work with the Cisco power injector? Anyone also had this problem before? Thanks, Ricardo Carvalho.

Does anyone have a solution for remotely getting the newer cisco phones (7941, 7961, 7970, etc ) to reread their configs (or even rebooting). I am running SIP firmware connected to asterisk. Check-sync doesn't seem to work anymore, I can't login to the phones as root because I am given a "challenge: <random digits>password:" prompt. occasionally I need to make changes to

I know this is on the wiki, I just want to confirm so I don't blow up my cisco phones. I've got several cisco 7940's all running using cisco power cubes. However, my boss wants me to switch just a few over to poe, but doesn't want to fork out the dough for a nice cisco poe switch, or anybody else's poe switch for that matter. So my question is, what is the '99.999%

As an alternative to the "expensive" PoE switches out there, I found the D-Link Web Smart DES-1316 switch for just around $400. Now, the issue is, it does 802.3af power and, as I've found out through previous discussions, this original 76?0 series phones (the non G variety) do not use 802.3af. So I'm assuming I just need to use the special cable thing as per

I am looking to replace all of the old "Bell" (POTS) phones in my home and office with IP phones. As you can imagine I don't have a huge budget to work with but I want phones that will provide acceptable voice quality and durability. There are basically three categories as I see it 1. satellite phones (low cost, low function) 2. primary domestic phone (good quality, POE capable,

Greetings, I mailed the list regarding an intercom system some months ago and we came to the conclusion that I should purchase a Polycom 501 phone. I'm now considering the purchase for this year, and I'm now wondering between the Polycom 501 and the 320 for the intercom. I don't need the spare ethernet on the phone because I would like to have my voice network separate from my

Hello people, I am having difficulties figuring out the POE power draw in watts from a Polycom IP601. I want to know how many IP601's can be powered from the Cisco Catalyst 3560G-48PS. The IP601 wallwart has: Input 120VAC 60hz 19W, Output 24VDC 500mA. I assume the output is appropriate value to figure out how many phones can be powered. The Cisco 3560 datasheet says "the 48-port PoE

Hi all, I'm looking for recommendations on ethernet switches for a new install. Ideally would want switches with at least 24 ports, ideally with a GE uplink, and that support PoE (power over ethernet) on every port. I've seen lots of switches, and lots of "power hubs", but the combination, which makes a lot of sense, seems rare. What is out there? Do the switches need to be

The documentation of how to use the 79xx series' phones and features with Asterisk is really hard to find and put together. The higher end phones like 7970 are more like converged PC+phone, a thin client to telephony and network apps. But it's really hard to target it as a development and deployment platform because the docs and techniques are so obscure. There seems to be a fair amount

Hi, I'm in a bit of a bind here, and I'd appreciate anyone who can help me quickly. I have a customer who bought a Linksys 224P switch (PoE enabled, with 24 ports). He also has 4 Polycom 501 phones, PoE bundle. Bizarrely, the switch doesn't seem to power up the phone, even though all ports have PoE enabled.

Hi Everyone.... Got a newbie type question regarding MOH & Cisco phones. I'm still new to Asterisk (very new in fact) & built up a AsteriskNOW box just to get something going. My simple test system has just 3 Cisco phones a 7905, 7940 & 7960. - Everything's running SIP. The 3 phones can call each other fine. - Can even leave (and retreive) voicemail messages. - No problems.

I am currently testing an asterisk server with some cisco 7960 phones. I have been having problems with phones rebootin using 6.3 firmware in the asterisk voicemail menus. The phones reboot after a dozen or so random button presses while in the voicemail menus. To try and fix this, I upgraded to sip 7.1 only to find that now the phones reboot even if i'm trying to press a button to

Hi, Are there any resellers of phones that can take power over ethernet in Australia? All I can find for sale online is the BT-10[12], which is cheap but not featureful enough, and the Snom 190, which is about right, but neither of them support PoE. I'm particularly intereseted in the Snom 220 with the keypad expansion for our receptionist. Although, could you make a PoE split-out cable

Hi List; Can someone advise me which IP Phone model that has buttons that can be assigned to do specific functionalities (call pickup, call formward, call appearance) and a transfer button and hold button? Which is the best of the following (that has buttons can be assigned to specific functions): Cisco 7970 or 7960 Polycom 501 Grandsream IP Phone Budge Tone 1001 or 1002 Linksys SPA 942 or 922

Ok, not exactly an Asterisk problem, but... I picked up some SNOM 200 phones because SNOM's have been recommended for use with Asterisk and they have line buttons that can subscribe to presence. However, they don't appear to power up when connected to my Negear FS108P, which is an 802.3af Power-over-ethernet capable hub. I am pretty sure these are the SNOM 200b, in that the ethernet
