separate voice and data 2

[ilpadrino]

Does it make any sense to separate voice and data? We would still notice savings just by eliminating copper lines.

For example, I already use a T1 for data, should I get another T1 (PRI) for voice, rather then trying to combine?

What are your opinions?

 

[ccmuser]

How many voice calls do you expect? What codec? What types or routers?

 

[computerhighguy]

I suggest seperating them. Make life easier. If they are on the same router, and your router goes down, you lost both voice and data. If they are on seperate routers, and one goes down, you only lost 1 of the 2.


It is what it is!!

It sounds like you're talking about services from your provider, correct?

Are you talking about converting your T1 to shared service?? as in some channels be data and others be voice from your provider??

If you want a PRI, then you cannot combine them.. Service providers don't offer that option..

So in my book, i'd leave the data T1 alone, and get a PRI for your PBX...

One thing to look at, is that you need to make sure your PBX will support ISDN PRI.. If not, then you might need to look at a Voice T1 with a channel bank..

Actually that is not true. I recently received quotes from several service providers that offer PRIs with both voice and data.

Well must be different in your area..

Here we have SBC, verizon, sprint, and your other knock offs.. to my knowledge they still don't offer that yet..

anyways, cool.. for people who don't need a Full T1 for data (actually need more these days) it's a better solution than going with a regular voice T1..

I have just about every player there is. It really depends on the providers switch capabilities. If the phone system is my responsability, then I would seperate the data from the voice (assuming the company was of sufficient size and the cost was justifiable). I sure don't like the single point of failure for both my Data and my Voice.

My original question was probably not stated correctly. What we're going to do (to begin with) is just use the data for inter-office dialing to avoid tolls from city-city. Every branch office will have PRI's. If PRI's go down, there are copper backups. If data circuits go down this does not affect dialing over the PRI's.

VOIP comes back to central location via 3640 and switch to be determined.

I'm nervous about VOIP over vpn connections, but we may try that at some point also.

 

[computerhighguy]

Don't be nervous. If your VPN connections are reliable, then your voice will be too. I have a VPN between NJ, USA and Munich, Germany that hops 5 different carriers and total 28 total hops between them and us. I have an average of 98 ms one way and it sounds like they are in the next room. I am using G729 codec. We have had 0 problems becuase our VPN is stable.

I would be very scared to implement this on a new install... If you're looking at ordering circuits, you have no idea what you're getting into..

If you currently have the VPN connections going, then you could put some load on them for a few weeks / months to get a reliable viewpoint of whats going on..

Buckweet, I don't understand what you mean by "ordering circuits, you have no idea what you're getting into". We have several out-of-state site-to-site vpn's that work well for data. My concern with VOIP over the internet is the number of hops and other contributing factors such as congested links which you cannot control.

Do you all have any suggestions for switches between the routers and multitech devices which will provide QoS? My 3640 should be fine for our point-to-point circuits.

 

[computerhighguy]

What do you mean by Multitech device?

[BuckWeet]

What I'm saying is that if you're ordering new circuits, you don't have any clue of the characteristics of the routing, latency, etc.. that it may take to get to your destination... You don't have any predictability of the circuit because its new...


data is a totally different story than voip..

Multitech gateways. These may connect my network to Nortel equipment- we haven't made any commitments yet.
