fxos, and an assortment of SIP endpoints for phones) for about 5 weeks now, and
I've been really happy with it, but I'm still having an echo problem that I've
exhausted google with, and can't get straight...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I think I've determined that because I'm using $7
voice modem clones for my FXOs that bad echo is going to just keep being a pain
to me... I think I should have only tried going through "proof of concept"
state with them, switching to something a little better quality when it was time
to actually commit to Asterisk. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, my question is "What's better and why:
1: a 'real' digium PCI card with two fxo plugins, or using a couple
external SIP fxo units like a grandstream, zoom, or similar" Personally, I
think it would be desirable to keep the FXOs out of the asterisk box itself,
just to give me future flexability to move to whatever the platform of the day I
want to put asterisk on, without dealing with a PCI card to move, but if the
consensus is that the voice quality and support for the digium board is the
best, then that's what I'll do.. </FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>So, any comments on relative quality of these
devices, and/or ones I've missed?</FONT></DIV>
<DIV><FONT face=Arial size=2>1: Grandstream HT-488</FONT></DIV>
<DIV><FONT face=Arial size=2>2: Zoom 5801/5802</FONT></DIV>
<DIV><FONT face=Arial size=2>3: DGM-TDM02B (TDM 400P with two
FXOs)</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Are there any IAX2 FXOs that I'm missing?
That seems to be an area that's oddly not taken care of...</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Any hints would be greatly
appreciated!</FONT></DIV>
