I've been looking at various solutions for getting FXS and FXO lines in and out of asterisk. one solution is using TDM-400 cards. Another solution is using the grandstream GXW400x and GXW410x gateways. Cost per port seems lower on the gateways and no pci slot is required. Why would one choose to use the TDM-400 cards? what would be the advantages and disadvantages of each approach? Eric -------------- next part -------------- An HTML attachment was scrubbed...

Might not be lower in cost but when you take into account the cost of the server it would be - how about checking out the Vdex-40 appliance if you need 4 pots lines or less. http://www.taa.com/products-vdex-40.html Cheers, Dean ________________________________ From: asterisk-users-bounces at lists.digium.com [mailto:asterisk-users-bounces at lists.digium.com] On Behalf Of Eric Fort Sent: Thursday, 31 July 2008 4:20 PM To: Asterisk Users Mailing List - Non-Commercial Discussion Subject: [asterisk-users] comparing pots solutions for asterisk I've been looking at various solutions for getting FXS and FXO lines in and out of asterisk. one solution is using TDM-400 cards.

We tend to use, for hooking up our analog agent phones, the discontinued Zhone zPlex-10 T-1 channel bank... though I suppose that's only cost effective, even at the $250 used we pay for them, if you already need to have a T-1 card in the machine. Going from a single to a dual or a dual to a quad T card is cost effective. Putting in a T-card from scratch, maybe not so much. Cheers, -- jra -- Jay R.

External gateways would also be easier to scale when you need more lines. Does anyone have experience with the Grandstream gateways? Are they more reliable than their GXP2000 phones? Can they actually provide support yet? regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com
