Hello I have a working * server with a TDM card and 4 FXO ports. We have 4 lines now and need to add 2 more lines (and possibly two more later). I'm wondering the best upgrade path for this situation. The simplest I can invision is adding another TDM400 card with 4 FXO ports, and use 2 now and the remaining 2 later. Are there success stories with using 2 TDM cards? Any info will be appreciated. Thanks -- Jim Freeze -------------- next part -------------- An HTML attachment was scrubbed...

Jim, I have 2 TDM400s in my * box (as well as a T1 card). I use all 8 ports, and aside from some minor echoing during peak periods, it's running smooth as ice.

A TDM04B (4FXO) cost around $378 at voiplink.com, while a Grandstream GXW-4104 (also 4FXO) cost $250 at voxilla.com., and the 8FXO version costs $400, almost the same as the 4FXO card. Having the pstn->ip conversion outside the server reduces the load and makes an easier install. I'm using the GXW-4104 , and besides it has trouble detecting danish callerid (a standard not used anywhere else in the world...), i have no complaints against it. Imho, ymmw etc. Leif
