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

Adam: Thanks for putting up this page. But something is wrong. In particular, our Powerware 9135 is a three phase UPS system with THREE 480 volt outputs. So the displayed voltage is not correct -- in fact there should really be THREE voltages displayed, all around 480v. Nut developers: I am copying the NUT mailing list to see if anyone can suggest how to fix this. NUT developers, see the

Hi, I have just started to setup and configure my asterisk box and am having trouble with it. I have a dlink nic in the box as well as the digium card. When the nic is in there by itself it works, but when I put the tdm400p in, there seems to be some sort of conflict with the network card. The tdm appears as another type of network card, which I don't think it should, should it? It shows

Hello, We have an Eaton 3S 550 UPS using NUT tool to send power loss event. By default the power voltage threshold is set to 85 volts. If the voltage is less than 85 volts, it will trigger ONBATT event from NUT. Is there a way in NUT we can change the threshold from 85 volts to a lower voltage like 40 volts? We were trying to change ups.conf to modify the output of upsc ..., but looks like it

I am located in the UK, and I am using Sipura spa-2000 adapters to connect analog phones to a voip network. The network connects to the PSTN as well via the Sipura spa-3000 adapter. I would like to provide surge protection for the spa-2000 and the spa-3000 adapters. 1. For spa-2000, fxs port: What is the maximum tip-to-ring voltage before damage to the the adapter occurs? 2. For spa-2000,

Hello, I was wondering if anyone had any ideas to a problem I am having. I have asterisk installed, and running. All extension phones are analog on FXS ports. The phones call each other and even transmit caller ID information but they DO NOT RING. Here is my setup: T400P Quad span T1 card currently connected to a CAC I w/ 12 channels of FXO for incoming lines and 12 channels of FXS for

Hi All, I have what is probably a 12 year old (or older) Compaq R3000 UPS plugged into a FreeBSD 8 system running NUT version 2.6.5 This UPS contains a total of 16 batteries in 2 banks of 8, each battery is 6 volts and the bank produces 50 volts. The UPS monitors battery voltage and the battery charger in the UPS works like this. For about 2 days it will apply a charge/float/topping

Hello, I am using Nut 2.8.0 (2.8.0-7 packages) Debian 'Bookworm' in it's Devuan form 'Daedalus'. When I look at my Eaton (ex-MGE Powerware) E5115 UPS boxes in NUT 'upsstats" I am confused by the battery readings. Under the 'System' column I can click on the link and obtain a GUI with a few meters. The NUT 'upsstats' battery voltage meter for these

I am trying to get the handytone 286 to make a very simple call to * and having problems. It registers with * just fine, but when I place a call (to echo test, for example), the RTP stream seems to have problems opening. Here is there error I get in *: WARNING[98311]: File chan_sip.c, Line 464 (retrans_pkt): Maximum retries exceeded on call 20d1c411-e210-5f3d-3f88-19035c8fcb26@192.168.2.6 for

Hello Jeff, `upsstats` by itself only relays and renders the information provided by a NUT data server (upsd) and the NUT driver for the device. So you can revise the specific reported values with e.g. `upsc` command-line client to be sure. What I think happens here is that the driver uses a `battery.voltage.low/nominal/high` group of readings which does not match the hardware circumstances

Hello, I bought a Grandstream Handytone 486 to forward incoming calls from our old analogue PBX to the asterisk server. My first test was connecting an analogue phone to the Handytone and calling a sip phone - worked. Now I used the same cable to connect the line port of the Handytone to the analogue pbx. When I call the number of the analogue PBX I hear a clicking inside, but the call

Things are going along well, but there is one remaining area of confusion...."units". I understand exponents now...it's basically how you pass decimal values. That's easy enough. But "units"....in other words, I have a voltage I want to put in a report. If I include in the report descriptor the fact that it is actually a voltage, with units of "volts",

Hi, Just received recently released Grandstream handytone 286 ATA for testing. I can call ATA from any other extensions and conversations seems to be of quite good quality. However placing calls from ATA is not possible at all to any extensions. After dialing there no indications of any kind from ATA at all. It just "hangs in there". ATA is behind NAT, registers to an * with public IP

Hi, I am quite new to asterisk so I am not sure what is needed to figure out this problem. If more information is needed and not provided I will gladly provide it. I have a very basic asterisk setup. 1 x100p card and a grandstream handytone 286. I can make calls fine to most phone numbers from the handytone device the trouble seems to come when I dial this number 591-1079. It puts me through to

Hello, Some time ago i bought 2 OPTI UPS devices, but was really sad to see the page about the OPTI protocol on the nut page. But i don't wanted to give up :) So i sniffed the serial communication using the windows application/driver and found out that these PS (PowerSeries) devices are different than the ES series mentioned on the Nut page. They use some kind of ASCII protocol, with the
