[Asterisk-Users] How to use a data T-1?
I have a data T-1 available to me to do some testing of a new asterisk systemthat I am putting together. Do I just leave this T routed through my cisco router and plug in the asterisk system through a network card or do I need to get a T-1 card and use that? I looked on the voip-info wiki and it did not seem to answer this for me.

Re: [Asterisk-Users] How to use a data T-1?
Warren, My suggestion for testing would be just use ethernet hand off to the asterisk from the Cisco. You could bypass the Cisco but then you would need a T-1 card for the asterisk box and they are not cheap. I believe there are valid arguments for both choices though and ultimately should be decided by what you are planning as a final solution.

Re: [Asterisk-Users] How to use a data T-1?
You don't need a T1 card for a data T1. Just run it through your Cisco box send it over to your NIC on the asterisk box. bp On 6/19/06, Warren [EMAIL PROTECTED] wrote: I have a data T-1 available to me to do some testing of a new asterisksystemthat I am putting together.Do I just leave this T routed through my cisco router and plug in the asterisk system through a network cardor do I need to get a T-1 card and use that?I looked on the voip-infowiki and it did not seem to answer this for me.TIA,Warren ___--Bandwidth and Colocation provided by Easynews.com --Asterisk-Users mailing listTo UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users

TIA, Warren If this data T-1 just goes to the Internet then you would use it just like any other network connection at your cisco router. If this data T-1 goes between two sites of yours then you could use it either as a dedicated route between network cards on each end (that connect to cisco or other brand routers) or a voice route between two Asterisk servers with voice T-1 cards. The choice would be between capacity for say G729 trunks over a data link or latency as voice T-1s. -- Henry J.

John, Thanks for the quick reply. I do intend to get a T-1 card anyway. Would it be the same card for a data T-1 as for a voice T-1 just with different setup?

RE: [Asterisk-Users] How to use a data T-1?
Depends what you want to do! Do you want to do VoIP over that T1 to a provider or IP telephones? Do you want to hook up to the PSTN through that T1 as 24 voice channels, through a T1 card on your asterisk? If you want to use the T1 as 24 voice channels, the Telco is going to have to re-provision the T1 as a voice T1, because currently, presumably it is one big channel of data. You could have the telco do any combination of 24 channels, some voice and some data, if your DSU or router allows drop and insert of channels. It would then split the T1 into a voice side and a data side, each with part of the channels available. Once you have a channelized voice T1, it can plug into a voice T1 card in your Asterisk, but typically can't do data anymore, so if that's not what you intend, then please explain further.. -Original Message- From: Warren [mailto:[EMAIL PROTECTED] Sent: Monday, June 19, 2006 10:16 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [Asterisk-Users] How to use a data T-1?

Re: [Asterisk-Users] How to use a data T-1?
Steve, I want to end up with a system that will let me send and receive voice calls. I guess what I want to do depends on the best way to do that. Can I do more than 23 (decent sounding) voice calls on a data T-1 with someone else handling the final part of the call to the copper for me? If so than that is my likely final destination. I have a channelized voice T-1 currently plugged into my meridian system, but I would like (if realistically possible) to do as much of this over IP as possible for maximum flexibility. Is that a pipe dream or just silly given the current state of technology? I am lucky enough to work for a company that is letting me take my time with this, test the various options and come up with the proper solution. I am assuming (I know: dumb to assume) at this point that VoIP over a T-1 to a provider that can then route it to hard phones for me would be the way to go. Similarly, I would point my 800 number to a DiD hosted by a VoIP provider that would then route the call back to me. If that is an incorrect assumption, please let me know.

Re: [Asterisk-Users] How to use a data T-1?
Depends on the codec. If you are using ulaw, you will only be able to have about 23 calls. If you use g729 you can have as many as 187 simultanious calls on a data T1.

Re: [Asterisk-Users] How to use a data T-1?
So let's assume I am going to use G.729A. I am looking at using Polycom IP601 phones which support G729A directly, so the only licenses I believe I would need are for the calls going to voicemail or in the menu system at once - realistically that number never exceeds 5 simultaneous, since the phones can handle the CODEC and no transcoding is needed, so those do not need licenses according to http://www.voip-info.org/wiki-Asterisk+G.729+Licensing. It looks to me like, for testing, I can get a couple of the polycom phones and have a server using an IP on the unused T1. Assuming that is correct (which I will write up as an article for the Wiki if anyone is interested when this is all done), the next thing I need is a provider of VoIP service. Also, it seems like the server would go on the outside of my firewall with holes punched through for the phones which would be on the ind=side of the firewall. Would that be correct?

Re: [Asterisk-Users] How to use a data T-1?
After all the overhead, for uLaw you would need about 90kbps (give or take) and for G.729, you would need about 32kbps (give or take). Therefore, you would have the following: uLaw= about 17 calls g729= about 48 calls I am trying to start a voip service in my local area and sometimes seeing these numbers make me wonder how using VoIP for larger companies could possibly be profitable if you require a $500+ data T1 just have a decent connect (unless you use g729?) - Gabe Depends on the codec.

RE: [Asterisk-Users] How to use a data T-1?
If your T1 is currently configured for connecting you to the Internet, then your Asterisk just becomes a client on your network, and can terminate calls to Internet based providers by SIP or IAX. No reason for a T1 card or connection to the Asterisk. I don't have enough experience to say who may be the most reliable provider, but you can use any of them for testing. Others have given details of bandwidth requirements for the different codecs, and know more than I about that.. Once you get the basics connected, then any 800# provider should be able to point a number to any existing DID, or you can use a VoIP provider to provide an 800# directly. -Steve -Original Message- From: Warren [mailto:[EMAIL PROTECTED] Sent: Monday, June 19, 2006 11:09 AM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] How to use a data T-1?

Re: [Asterisk-Users] How to use a data T-1?
I honestly do not see the big deal about using g729. It is a one-time fee and you would only need to buy as many licenses as you have people in ivr or voicemail if you have g729 phones. For a business this is not a major expense. You are talking about spending $100-$200 (max $480 for all 48 potential callers if you don't have g729 phones) to expand a T-1 from 23 calls (PRI) to 48 calls by your measurement - a doubling of the usage of the T-1 for less than one month's cost of the T-1. ROI at less than a month? That's a slam-dunk for most businesses.

Therefore, you would have the following: uLaw= about 17 calls g729= about 48 calls I am trying to start a voip service in my local area and sometimes seeing these numbers make me wonder how using VoIP for larger companies could possibly be profitable if you require a $500+ data T1 just have a decent connect (unless you use g729?) - Gabe Depends on the codec. If you are using ulaw, you will only be able to have about 23 calls. If you use g729 you can have as many as 187 simultanious calls on a data T1. Remember, you have 1544Kbs of bandwidth. g279=8Kbs per call uLaw=64Kbs per call Just do the math. ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
Re: [Asterisk-Users] How to use a data T-1?
Well that is certainly all good news. The last hardware question I would then have is: What do you do for Echo Cancellation with this type of setup? Everyone keeps saying that the software EC basically sucks to put it bluntly. Is there some sort of hardware to do EC that can be used here? W Steve Jones wrote: If your T1 is currently configured for connecting you to the Internet, then your Asterisk just becomes a client on your network, and can terminate calls to Internet based providers by SIP or IAX. No reason for a T1 card or connection to the Asterisk. I don't have enough experience to say who may be the most reliable provider, but you can use any of them for testing. Others have given details of bandwidth requirements for the different codecs, and know more than I about that.. Once you get the basics connected, then any 800# provider should be able to point a number to any existing DID, or you can use a VoIP provider to provide an 800# directly. -Steve ___ --Bandwidth and Colocation provided by Easynews.com -- Asterisk-Users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
