We got stuck with 12 ip200e phones that don't work as the reseller promised. I am considering installing them on an asterisk server at the remote location. Has anyone done this or know if this is possible?

They certified the wan. We can get one to two phones to work, but can't get more than that to work properly. It isn't economical to increase the wan bandwidth. We are now using analog phones at this location. I am looking at using Astrisk and IP phones (preferably the ESI IP200e phones we already own).
The IP phones actually caused the main system to stop functioning properly. Display screens wouldn't update and features would break. So, not only did the drops in the IP phones make them worthless, they took out the main IVX 128 e system as well
what type of wan? how many remote ip phones? and no you can not use esi ip phones on an astrik ip system. so are you have a 128e and a 200e sitting around? i have done esi-link, remote ip, and local ip with no problem this does not seem right.

The IP200E is a phone system not a phone. You most likely have ESI 48 KEY REMOTE IP PHONES. We've installed many REMOTE IP PHONES and ESI IP200E systems. They are rock solid. Something is not right with your install. If you have bandwidth problems call quality will suffer on the remote phones. It shouldn't have any impact on your local digital phones. Email me if you need to dispose of those REMOTE IP PHONES.
You are right, I have 12 ESI 48 Key Remote IP phones working off of a IP200E. We had two different wan setups attempted. The first involved a 11mb wireless connection between the main building a DSL connection (~482K bandwidth) to the remote building on a 482K DSL. A second variation included dual DSL modems on a dual wan router.
The second setup was a direct line of site wifi 54mb connection using 80db linksys wrt54G with VAGI antennas.
The local digital phones tanked as soon as we had more than a couple of ip phones attached. The ESI vendor said we should just hook up two and forget about the rest!
Getting any voip product to work on this bandwidth would be a trick. Your reseller should have recommended a minimum 100mb network. I'm surprised esi allowed the sale on this network; they require the network be qualified to spec before they release the product to the vendor. It sounds like your vendor put this product on a network that will not support it. My advice is to contact esi directly give them your network specs. and see how they reply.
With your first solution, many network issues on your WAN could have affected call quality, but with the Linksys wireless routers the problem may be at the MAC address level. WRT routers do MAC address substitution at times (substituting the phone's address for the Router's LAN interface address). ESI's Voip protocol requires the MAC address in the packets to be correct at *all* times or you will have issues.
Is it a Ip 200e or a 128e. I'm wondering because the IP200e does not support digital phones, only IP.
ESI's remote phones use very little bandwidth on their own but any Voip solution requires a lot of overhead. If you don't want any glitches the entire link should never use more than 30% of the available bandwidth. Just because you'r eusing 802.11g doesn't mean you're going to get anywhere near 100Mhz bandwidth. Has there been a bandwidth test on the link?
There is also a 128e system at the main location. This is news regarding the linksys routers. I had actually tried two different versions of routers from linksys. The wap54g and the wrt54g. A bandwidth test was run several different times. The bandwidth was adequate as specified in the original certification of 480K+.
I was referring to network switches in reference to your wireless switches. Wireless doesn't always run at speeds as reliable as wire. You indicated you had an IP200 system. This would be an all voip system, not just remotes. You don't need 100MB for just the phones, you need enough bandwidth for everything on your network. esi also recommends dedicated dsl on both ends on Internet connections.
I made a mistake. I do not have an IP200e. I have a 128e with the VOIP add on. The network speed is 100MB for the switches (Cisco, linksys) for both implementations.
I agree that more bandwidth would be better. Our problem is that the network was certified by the phone installers, but it didn't work. On top of that they commented we should just use two phones instead of all 10 (this is unacceptable). $4,000/phone is a little steep.
Anyone want 12 ESI 48 Key Remote IP phones and the VOIP add on to the 128e system? Phones are in near new condition, hardly been used!

I bet your installer only put in an IVC 3 instead of a 12. Your 128e will max out at 12 remote phones. These are the types of installs I thrive for and can get working.
I cant beleive your installer said "install 2 and call it good". What did they do after that? Walk away? If they cannot resolve this for you, call me and I should be able to resolve your issues remotely.
Geez, I cant stand a 1/2 a$$ install or broken promises. This is why sales and techs dont get along. Fortunately I can do both
If you have already made arrangements with Wine to sell the IPR phones disregard my offering to help getcha goin'.
Hope everything works out for you. Your install to me sounds simple and I have done similar. Using WiFi, direct line of site, microwave, etc...
