<p class=MsoNormal><span class=gmailquote><font size=3 color=navy
face="Times New Roman"><span style='font-size:12.0pt;color:navy'>You’ve
got a decent server. Generally the limiting factor for the number of
simultaneous calls is more about server memory. That server could likely handle
124 simultaneous calls, but you would be prudent to double that memory size.
Make sure you are running at 100 full especially if you are using G.711. 10
Full uplinks won’t cut it if you are running that kind of bandwidth.<o:p></o:p></span></font></span></p>

<p class=MsoNormal><span class=gmailquote><font size=3 color=navy
face="Times New Roman"><span style='font-size:12.0pt;color:navy'>As for the
DSP, you are right to be concerned about the Digium cards, but not because of
the DSP. The DSP is not where you will run into problems. Digium cards feature 2
year old circuitry and do not play well with other devices. You have to take
care not to share interrupts with any components that may be active on that
system. Sharing an IRQ between a Digum card and an Ethernet card would
certainly spell disaster in my experience.<o:p></o:p></span></font></span></p>

<p class=MsoNormal><span class=gmailquote><font size=3 color=navy
face="Times New Roman"><span style='font-size:12.0pt;color:navy'>From personal
experience, I no longer use Digium hardware since I could rarely push a quad
port card to more than 13 channels per T1 circuit without the card failing
miserably. HDLC aborts abound.<o:p></o:p></span></font></span></p>

<p class=MsoNormal><span class=gmailquote><font size=3 color=navy
face="Times New Roman"><span style='font-size:12.0pt;color:navy'>For now, I
only use Sangoma cards. These don’t have the IRQ issues and I have had no
problems pushing their cards to their maximum. I recommend echo canceller
enabled cards for any T1/E1’s you may use that are not long distance
carrier lines. <o:p></o:p></span></font></span></p>
