Additional details

Some additional details for your chart;
Polycom SountPoint 3XX series, does support PoE, also works with a 24 VDC local power supply, has a WEB GUI, can also be loaded from TFTP, can support 2 lines

SNOM 300, runs from local 5 VDC power supply, has WEB GUI

Cisco 7940/60 Must first be flashed with SIP firmware, does support PoE, runs from local 48 VDC power supply, has a simplified "list only" WEB GUI but must be loaded from TFTP to function, 7940 supports 2 lines, 7960 up to 6 lines

Thanks Mark for putting the chart together, I am sure it will be helpful for those just getting started in VoIP over mesh

recommended deployment pattern?

For your deployments, are you using some type of pbx or sip server? Or are you dialing by IP or creating local phone books of some sort?

I really like the idea of not having a centralized server to depend upon, but I also like the ability to provide off-mesh calls or having a centralized phone book.
 


Moderator note: This topic moved to a new thread under VOIP. Please reply on that thread.

Since most (all?) VoIP phone

Since most (all?) VoIP phone support a central phone book via LDAP or HTTP, maybe a small program could be written to create and sync-up a phone book across the mesh and write them to a local LDAP/HTTP server. The phone just sees the local service.

For it to be truly decentralized, some type of gossip/peer discovery protocol would have to be used for info exchange.

Could be a fun project.

2 more phones in use plus additional tested

Grandstream phones I am using.  

GXP2160 Yes 12V DC yes yes Up to 6 lines; has extra speed dial buttons programable through the web interface.
GXP2140 Yes 12V DC yes yes Up to 4 lines;

Both phones can also dial direct by ip address.  

I have tried the GXV3240.  Works the same as the others but is touch screen and can make video calls. It runs a version of the android operating system and yes I did try to install the sevral mesh software on it.  It did install and did work sort of.  Worked fine in speaker mode but if you want to use the handset the software and the phone gets confused.  I tried 2 phones over mesh which worked fine but I am sure once you get more then a few there will be bandwidth issues.  

I am also using the UCM6104 as my controller.  Very easy to configure, only 12v power requirement, It has the ability to add 4 land line connections or use an online phone service if internet is available for outside calls.  There is also instructions on grandstreams website on how to link together multiple controllers.  
They can be used as a portable unit or central server setup.  

Hope that helps add to the list and answer the controller question.

GXP2160 Phone Settings to get Registered on Broadband-Hamnet

I have a GXP2160 phone but all it sez on the screen is "Account is not registered" and I can't dial out.  I did receive an incoming call from Joe Ayers but soon as he hung up the "Account is not registered" returned to the screen.  So, what setting in the admin portion of the web browser interface did you set in your GXP2160 for it to work on the mesh?

kc8rgo
Did you get it working?

A friend has this phone and got the same messages.  Did you get it working?  Do you have a procedure?

Thanks

Means that either:

Means that either:

  1. your phone cannot contact your PBX server
  2. your username/id is invalid to the PBX server
  3. your password is invalid/doesn't match the PBX server

If using "DIAL by IP", and account is not needed.
 

kc8rgo
Thanks Darryl, I will have

Thanks Darryl, I will have him find the parameter for dial by IP.

I had recommended that to him before and to also look for calling without registration.  I will look for the param list for that phone.  All he needs to start is IP dialing.

kj6ffp
True.  Sometimes amazon has

True.  Sometimes amazon has it for about $250 which is when I got it.    Yes it is pricey but if you don't feel like running your own server on a computer it helps simplify things.   It also does a really cool auto setup on new phones for you and auto assignees the extension if you turn on that feature.   
I wanted to be able to do that plus have the extra option to add land lines or internet phone service to it.  There are a few events we do here that having that feature would be useful.  We usually spend quite a bit of time running land line cords to our county Sheriffs trailer during the county fair and sometimes other events.   The old analog system that is in the trailer has never worked properly so we use our own setup.  This helps simplify things a lot for us where we can now place the UCM6104 in the fair building where the land lines are located and just run the phones over wifi or one network cable going to the trailers computer system.  
The UCM6104 does have tons of features most that we will never use but since it helps do auto setup and simplify the operation a few of us decided to pitch in a buy it.  Most of our radio operators in the area do not have the best programing skills so we thought this would make things smoother which so far it has. Hope that helps give an idea on our thoughts here.

Is it safe to run a 12V PoE

Is it safe to run a 12V PoE device off of a 24V passive source? My instinct says no but I wanted to make sure.
Use case:
Ubiquiti ToughSwitch TS-5-POE outputs either 0 or 24V passive PoE. I was wondering if I could run any of the 12V ones off of that.

I smoked an ipcam doing this once. Be sure to check the specs on any device that is plugged in.if the device doesn't take 24 volts, don't attach.

That's exactly what I figured

That's exactly what I figured. Is there a good way to step it down from 24 to 12 volts for the Grandstream PoE phones?

KG6JEI
They sell DC to DC switching

They sell DC to DC switching power supplies  24v in to 12v out (and many variants there of) that may work.

http://www.amazon.com/50-4W-ENCLOSED-DC-CONVERTER/dp/B00B88EAAO

This may be a bit big in this case but if you search you can find others (may need filtering) from smaller self contained modules.

Maybe a venerable 7812 voltage regulator chip might work. Be mindful of heatsink requirements.

Digi-Key

I've seen 5 volt versions of this on Digi-key. I'm sure that 12 volt versions exist as well. One nice thing about them is that if they get overloaded,they simply shut down and don't pass any power through.

Checkout this 24v to 12v gadget..
K7DXS
Does that step down or just

Does that step down or just inject? To put it another way if I plug it into a 24v passive PoE source, will it output 12v without me plugging the DC power plug into anything?

WU2S

Step down

The data sheet says that the input voltage is from 18v to 30v. The input side is the female RJ45.

AE6XE
AE6XE's picture
Correct,  the specification

Correct,  the specification says the 12v 'output' is on the 1/8" jack and builds up the fact of full 300'+ cable length (meaning 24v on the input side).    No need to build something equivalent and piece together all the parts unless you just want to.  Plug the cat5 into the 24v toughswitch port,  use this adaptor to directly plug into a 12v ipCam on the other end.  

The issue is more of a limitation on how many power-watts the ipCam/device needs and what this adaptor rating is.    The specs say 1W (probably spike), then says 0.75W elsewhere (probably continuous).  

If you have a PTZ ipCam drawing 2+W of power, this is problematic.  If so, look on the vendor site to see if same device at higher power specs, or you would need to piece all the parts together from some of the other responses.   We're locally running a 12v ipCam PTZ over a 100' Ubiquiti toughCable Pro, but using the power supply that came with the ipCam--think it was a 2A.  There's an injector on the toughswitch side--so 0v port.    It is working fine.  But the issue is voltage drop at that distance to not affect the ipCam function.

How are these various phones

How are these various phones at dealing with jitter? In my test pings from a Nanostation M2 on a hillside pointing at my house, I was seeing ping times swing from 150ms to 700ms and back, with a link quality of 60%. It would probably have been better if my link quality was better.

IP Phones and Jitter

There may be a jitter buffer setting you can adjust. We use Grandstream HT701 analog telephone adapters (about $20 used) and discarded POTS (plain old telephone system) phones. The GUI for the ATA lets you choose 3 lengths for the jitter buffer, default is medium. But what helped us the most was reshuffling the codec order from the factory preset of most to least bandwidth intensive, to the opposite, that is least to most bandwidth intensive. It now sounds a little digital (like dmr!) but rarely drops packets. Our pings are generally a little better than what you've indicated though, but trying both those things may help(?)

We have use in Europe HamNET

We have use in Europe HamNET IP Phones (and soft phones: for example PhonerLite with good codec OPUS) with asterisk PBX base on DUNDi protocol

You can see online status HamNET Europe PBX:

We have generate phone number base on callsign which is converted to DTMF code. We can use special WWW page which help generate phone number from callsign:

GXP2160 Phone Settings to get Registered on Broadband-Hamnet

K5DLQ

the phone settings should not

the phone settings should not be any different between AREDN and Broadband-Hamnet.  It's all about the PBX that you are connected to.

KE6UPI
Andriod

I use Android's native sip on my cell or tablet over WiFi or Cell. The PBX server is RasPBX.  http://www.raspberry-asterisk.org/ Yes it has FreePBX GUI. 

But I run a small codec like G.729 over wifi.. G.729 sounds like an old 3G cell phone.. But low bandwidth. So any wired SIP phone that can run G.729 and 12 volt or lower for field work. Also for field work I don't like POE. Something else you might want to think about is App-RPT for Asterisk.

if you have a phone or other

if you have a phone or other device that runs off 5vdc, then there is this option for field powering from a USB port:


I strongly recommend the one made by Tripp-Lite, it handles decent current draw, works over a wider range of applications.

Thanks for the recommendation

Thanks for the recommendation.  I purchased pair and test running both a 5V AirRouter and 5V Grandstream phone off a 20AH USB battery pack.  I am at the 75% capacity mark on the battery after running 12 hours.  Will indeed be handy for quick field deployments of mesh router and phone.  Previously I was using a 7AH 12V battery which we much bulkier along with 12V Linksys router and 12V Grandstream phone.

I'm looking for VoIP phones

I'm looking for VoIP phones that will run off 12V batteries without excessive drain. I have several Cisco IP phones now, but they all require 48VDC.
My guess is that converting the voltage is going to be very costly from an energy standpoint, but has anyone done this, or have a resource on how to do it?
Thanks.

The Grandstream GXP1600

The Grandstream GXP1600 series run off 5v, the GXV3240/3275 run off 12v.... though the latter being video phones - they draw more current.

Do you have a USB port somewhere handy, look at post #31

Cisco IP 7940 and air Router

I have been playing today with an air Router running AREDN 3.16.1.0 but when plugging the Cisco IP phone into the air routers LAN ports it doesn't funtion correctly, by that it doesn't reach the PBX. Plug it into a Linksys router and it works fine.
Put a switch between the UBNT air Router and the Cisco phone it works fine.

I have the feeling its to do with the VLAN's but not sure the diffrence of the Linksys LAN ports running HSMM and the UNBT running AREDN and why the Linksys works.

Which Jack ?

Hi Andy,

When running AREDN code on an Air Router, the right most jack (when looking at the back of the node) is the DTD port, running VLAN 2 tagged. Make sure you plug your phone into the next three jacks to the left of the DTD jack. The jack all the way on the left is the WAN jack. You certainly don't want to plug your phone in  there! :-) Just beware that the 4 jacks in a row are not all LAN ports, just the 3 left-most ones.

Do you get the same condition if you plug your Cisco phone into the middle 3 jacks? Your post did not mention which jack into which you plugged your phone.

Mark, N2MH

Should be OK

Kevin,

I've configured both the Yealink T22P and a T19 phones. Aside from the number of lines, the configuration pages look identical. I would expect the same to hold true for the T21 phones. They do work well on the Mesh. Be advised that dialing by ip address on these phones is difficult compared to the Grandstream series of phones. If direct ip dialing is important to you, you may wish to look at the Grandstream phones instead. If all you want is a phone that will be behind a pbx, then Yealink will work well for you.
