I'm trying to understand why vendors keep making 100Mbps integrated 1-port switches in their hardware SIP phones. Even the recently-announced D40 and D50 Digium phones are limited to 100Mbps. Only the more expensive models (like the D70) can run at 1000Mbps. However, you can't expect a firm with hundreds of extensions to buy the most expensive model... And gigabit speed is important when "sharing" the network with a PC (because PC apps may "require" gigabit speed). The day will come when medium or low-budget hardphones will have integrated gigabit switches. But is it THAT expensive to put in 2 gigabit ports in a hardphone nowadays? Or is it just marketing? How much would it take for Digium to sell their D40 phones with gigabit ports? Vieri

It seems to me that low-end phones are still designed today to compete on price with analog phones as if a large share of decision makers wouldn't pay a premium to benefit from VoIP features. If people markets these low-end phones this way, I'm sure they must have a reason for that but that doesn't change the fact that I'm still a bit surprised this remains the norm these days.> > How much would it take for Digium to sell their D40 phones with gigabit > ports? > > Vieri > > > -- > _____________________________________________________________________ > -- Bandwidth and Colocation Provided by http://www.api-digital.com -- > New to Asterisk?

From everything I've researched to date, my understanding is most locations have chosen to double their port density and continue to service the phone and computer on separate ports than to share a single line for both computer and phone. Reason primarily mentioned being troubleshooting concerns. If this is the case, the second port is not required, and become nothing but another gimmick to sell to you. Is this everyone else's experience as well? Thanks, Jason "Experience is what you get when you didn't get what you wanted."

I think that implementing QoS is a better way to handle voip on a 100 Mbps network, than to upgrade everything to 1 Gbps On Mon, Feb 13, 2012 at 10:48 AM, Hans Witvliet <asterisk at a-domani.nl> wrote:> On Mon, 2012-02-13 at 09:32 +0100, Benny Amorsen wrote: >> "Jason W.

Jason A standard SIP VOIP phone will use less than 100k per voice call. For example I have several bussiness customers that have a dedicated DSL line and they do up to 6 lines very well on that 1.5x384 (we do g729 which is 37k per call). If your networks drops can test solid at 10mb you should be in good shape if they do not run solid at 100mb you should force the switch port to negoitate to 10mb not 100mb. Make sure the POE switches you are looking at allow you to force the port speed this may save you in the long run. Also make sure that the POE switch can handle the load and run lengths you are looking to put on it. Bryant ---------------------------------------- BrFrom: "Jason W.

As we move forward, we'll be testing and making a phone selections. No doubt we'll run into this. Are you saying if the phone is stated to be a 10/100 phone, it still may not work at 10?
