I have a client that has 10 POTS lines incoming. There is no other option for lines here. I have 3 options I can see: 1. 3 TDM400 cards 2. An external SIP/FXO gateway 3. A T1 card plus a channel bank. Does anyone have any thoughts on these 3 or suggestions on keeping the cost down? -Darren

Having used the TDM card since it came out, I'd be very hesitant to use them in this type environment. Very likely to be a high maintenance/support item for you. They are sort of okay in small soho environments, but if you dig through the last year's worth of postings, you'll see lots of quality and audio level issues with the TDM. The gateway approach will work, but you'll probably spend a fair amount of up-front time finding one that works well and getting it set up to be reliable. They are rather expensive as well (comparatively speaking). The T1 card with channel bank will likely be your least cost approach after considering setup time, ongoing support costs, etc. Generally considered the most solid approach with *.
I agree about the TDM.....nuff said. There looks to be a nice gateway for $1000 or so. The problem I see with channel banks is that any of them with FXO cards, even on ebay are $$$. FXS are a non-issue. -Darren -----Original Message----- From: asterisk-users-bounces@lists.digium.com [mailto:asterisk-users-bounces@lists.digium.com] On Behalf Of Rich Adamson Sent: Thursday, June 23, 2005 4:25 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: Re: [Asterisk-Users] 12 FXO ports into Asterisk> I have a client that has 10 POTS lines incoming.

I'm looking at $1500 for the bank plus $500 for the T1 for a 10-port FXO solution. 3 TDM cards are significantly less than that. Any other ideas? -----Original Message----- From: Garrett Smith [mailto:gsmith@voipsupply.com] Sent: Thursday, June 23, 2005 6:52 PM To: Darren Wright Subject: RE: [Asterisk-Users] 12 FXO ports into Asterisk I would go the T1 card plus a channel bank.
