[asterisk-users] [OT] switches
Pardon, this might be off-topic. I'm reading: http://en.wikipedia.org/wiki/Network_switch For a setup of ~5 agents, would I be wrong in thinking that a generic 16 port unmanaged switch would fit the bill? The first model to come up for me in an Amazon search is: http://support.netgear.com/product/fs116 Is this a reasonable choice? Would I be wrong in thinking that most any Fast Ethernet switch would be fine for Asterisk? thanks, Thufir -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Hi, For a very basic setup it would work, but I would suggest POE at a minimum, and vlan support if possible.

VLAN and PoE support would obviously be better for convenience and security, but those are not mandatory. -- Bertrand LUPART -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

If your only running the phone on the port, there is no need for GigE to the phone, and many phones only support 100Mbit. If your running phones with built in switches, a computer off the phone, and the phone supports GigE, the GigE will help keep the computer from overloading the total available bandwidth, but that is a very low chance of being an issue to start with. GigE all ports vs GigE for your server, and 100Mbit for your phones really is not a major difference, but the price difference between the two is also very small now days, and you are buying equipment with a reasonable service life (3-8 years in my opinion), so it's a balance between a few extra $ now, or waiting and seeing if you want it in the future, and paying some amount of money to swap it out. Most of the deployments I have done are with 100Mbit POE to the phones, and GigE for uplinks between switches and to the Asterisk server(s) -Harry thanks, Thufir -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Unless you are doing things wrong (network loops…), your switch shouldn't be an issue for such a small network. Depending on the voice codec you use, a VoIP conversation if a few kB/s, so don't be obsessed with GigE. Some hardphones have an integrated switch. Don't daisy chain phones this way, and be careful not to invert LAN and PC port. -- Bertrand LUPART -- _ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- New to Asterisk?

Any port with a hardware SIP phone plugged into it almost certainly won't be gigabit :) Anyway, an uncompressed (A-law or micro-law) voice connection is only using 64 000 bits per second. Compressed formats use even less bandwidth. The SIP signalling adds a bit of an overhead, but not much. That's probably why most SIP phones have only 100 or even 10 meg ports. > Small office, about five agents. To be honest, you'll probably be fine with a £9.99, 8-port TP-link switch -- but then you'll need power packs on all your phones (we power ours this way, and find it helps to reinforce the concept of the phones being unlike analogue POTS phones). There will already be mains there for the computers and monitors. If you want a PoE switch specifically to remove the need for a power pack on each phone, just add up your requirements for power and ports; double them, to allow for the future; then find switches that meet these minimum requirements, and buy the cheapest-but-one. The limiting factor with a switch carrying IP telephony traffic is not bandwidth, but routing table entries; and even cheap switches nowadays will usually take 1024 entries, if not 4096. -- AJS Note: Originating address only accepts e-mail from list!

Remember that that zyxel 16 port switch is only 8 poe ports. If your phones are 802.3af or 802.3at, you could look at the ubiquiti line of switches.
