Two Vonage Boxes On Same Network

Is it possible to use two Linksys Vonage boxes on the same network?

This is my current setup (it's more than an average home network)...

Internet comes in, and goes through the router. The router is attached to a Cisco Catalyst 2912-XL Switch, and on that switch, is two seperate Linksys Vonage boxes...

Will this work? Early this morning, my phone couldn't receieve a call, and yielded a busy signal, but my fathers was working fine.. Right now it's all working fine, but was it my setup, or just a Vonage glitch?

Also, I don't know if it's because of this setup, but my Vonage box has the most weird "ringing" sounds after I dialed a number. For example, sometimes (most actually), I hear "two" ringing sounds overlapping each other, or sometimes it's a scratchty modem sound (but when the other party answers, all is fine)... Yet, my fathers box runs completely fine, with no problems, again.

I'd check out the issues that you're having with your Vonage adapter by plugging it directly into the router, or even directly into the modem (temporarily). Your setup sounds like it ought to work, but it depends on that Cisco switch. I'd be a lot more comfortable with your adapters both plugged into the router and with QoS set on the router to give priority to the adapters.

my router isn't a consumer router, it's a Cisco also (don't know the model at the moment), and only has two ports, WAN and LAN, and it "needs" the Cisco switch to allow more than one connection..

i tried plugging my phone adapter into the modem directly, and the double-ringing sound still does happen, and my phone is infact ringing (sometimes still however)..

i know the basics to the Cisco IOS when it comes to the switch and the router, but do not know commands for QoS on my Cisco router.. (non of the equipment in my house is a SOHO box, it's all data-center grade equipment, as I run a domain and everything)..

perhaps the domain controller on the network could be hogging some of the bandwidth? the network runs completely at full duplex 100Mbps, and if im not mistaken, my Cisco switch has about 24 megabytes of buffer memory..

It sounds as if one of your adapters is behaving oddly, and you should probably discuss this issue with customer service. Other than that, if they're both now working through the switch and continue to do so, then you should be home free. If the adapters are also routers- you didn't specify which adapters you have- then you have the option of plugging one into the other.

They are routers, they are the RT31p2 (i think that's right), but when one is piggy backed ontop of the other, only the last one to connect can "receive" a call..

im going to go into both my router and switches IOS and see if theres anything in it for QoS..

Do both of the Vonage boxes have the same IP? Shouldn't they be different? Couldn't that cause a problem?

Sorry for no solution and only questions, but I'm planning to do something similar.

The two Vonage adapters do need to have different IP addresses., If they are getting their IP via DHCP that should be no problem. If they are static then you need to be sure they are not the same and, once different, that they don't conflict with anything else on the network.

I am using two Vonage adapters (a PAP2 and an RTP300) with no problem. I have them both connected to ports on a switch behind my router and am not using the router functionality of the RTP300 at all.
