<div>if i went with an SDSL line, don't those lines hook up to a common point, the DSLAM?</div> <div> </div> <div>i do like this idea of faling over not to a pri but another cheaper high speed line.<BR><BR><B><I>adebayo omo-dare <bayo0@yahoo.co.uk></I></B> wrote:</div> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>I wouldn't first presume that there is any law that states you have to run VoIP over a PRI. Other technologies exist such as <STRONG>SDSL</STRONG> - with some providers speaking of crazy prices such as <STRONG>£65pcm</STRONG> for <STRONG>2Mbs</STRONG> <STRONG>5:1</STRONG> contention ration and <STRONG>£100</STRONG> for <STRONG>1:1</STRONG> (U.K) - should be even less in the states if that's where you are. </DIV> <DIV> </DIV> <DIV>One option, but not the only one, would be to drop your pri when your contract ends and take up SDSL - and voila an initial saving, in your
case, of a 000 or more in the year.</DIV> <DIV> </DIV> <DIV>You could also have two SDSL lines for a little less than the price of the PRI. Both lines would not only serve for High Availability -possibly even better availability than single PRI- but could also, actively, both switch traffic, giving you 4Mbps of bandwidth for your VoIP, or if you choose, some other requirement while not required as failover - all for the price of less than one PRI.</DIV> <DIV> </DIV> <DIV>Then there is compression - 64k non negotiable, per channel for PRI, and flexible -i.e., less the 64k- for VoIP (International high quality Calls are transported at 16k), giving you the capacity to potentially service more traffic with less initial outlay. </DIV> <DIV> </DIV> <DIV>Other real cost efficiencies come in the form of the fact that IP-to-IP (local/national/international) calls are free. So if you have a lot of inter-branch communications,
or communications you can switch on to IP, you can totally erradicate this cost - unlike with the PRI where you will still be subject to payment.</DIV> <DIV>Think like this - say I have two offices - one in london and the other New York. How much will I save by moving my calls on to VoIP with no per-time or call setup charges.</DIV> <DIV> </DIV> <DIV>Features related to OAM&P, can also be faster and cheaper with you having a lot more power in your hands.</DIV> <DIV> </DIV> <DIV>In real senses, and with regards to reliability, you should take in to consideration the great moves currently being made by telecom companies (incumbents most especially), with regards to a complete shift to NGNs, which have a strong focus on <STRONG>ToIP</STRONG>. With new fiber (FTTP), new technology, etc, a lot of networks are highly reliable at the present moment - I guess this would also depend on where you are.</DIV> <DIV> </DIV> <DIV>The thing about it is
that complete IP networks in terms of telecom now look inevitable. And whether you do it yourself or it is done for you - it is the way things, many expect, are going to be in the next 5 or so years.</DIV> <DIV><BR><BR><B><I>stan ford <stanford510@yahoo.com></I></B> wrote:</DIV> <BLOCKQUOTE class=replbq style="PADDING-LEFT: 5px; MARGIN-LEFT: 5px; BORDER-LEFT: #1010ff 2px solid"> <DIV>I'm confused with something, maybe someone can explain to me. </DIV> <DIV> </DIV> <DIV>if your currently on a pri and are considering moving over to VOIP, that means you would have to purchase a t1 or fractional t1 for a your voip connections. </DIV> <DIV> </DIV> <DIV>but then, voip connections aren't as reliable as PRI. so then you would probbaly have to get a PRI failover. </DIV> <DIV> </DIV> <DIV>but then having a PRI failover means that you now have to pay 400 for a T1, then another 400 for your PRI line. wouldn't have you have just defeated the cause of
savig money by now having to have a PRI on standby? now costing you 800 a month? wouldn't it almost be the same price to stick with the PRI only?</DIV> <DIV> </DIV> <DIV>is anyone out there, using a VOIP only with no failover?</DIV> <DIV>__________________________________________________<BR>Do You Yahoo!?<BR>Tired of spam?
