atcomsystems.ca/forum Forums TDM Business Telephone Systems Inter-Tel Telephones & Systems VOIP Lines for backup to PRI?

I have recently knocked off my backup phone lines as I had them with the same provider as a T1 that i was switching to a Fiber Provider. I ran reports and saw that we never used them as overflow and my PRI never goes down so i figured why pay 240 a month for lines i don't use. Right?

Now i feel like i'm flying w/o a safety net, so i was wondering if anyone has implemented, or could comment on how to implement, VOIP backup lines from a provider such as Vonage or others. I've got the old 40 Pin that used to connect to the backup line channel bank, anyone know of a VOIP appliance i could get to hook in to that?

Or any other ideas?

Since I have 2 ISPs, both which are different then the PRI provider i figure the odds of the PRI going out and both ISPs are pretty small, so if i could get 6 or 12 VOIP trunks for 50 or 100 a month that is worth it to me since they will rarley be used but will be there if necessary.

Any thoughts are apprecaited.

Thanks!

I've done a little digging online, and found the Linksys SPA8000 Analog Telephone Adaptor (ATA).
It would plug into my LAN via ethernet and into my inter-tel PBX via either RJ11 or 50Pin RJ21.
Since my last backup line provider had a channelbank using the RJ21 interface i'm thikning i could just snap this in there and use the same setup on the Inter-Tel ssytem as i did before with those Trunks.

It seems that I could get 8 trunks with this box which would be enough for backup.

Can anyone shoot holes in this? Or Has anyone had experience with the SPA8000 ATA?

Thanks!
