<span style="font-family: Arial, Helvetica, sans-serif; font-size: 10pt">One FXS port can only handle one call. A PRI T1 gateway can handle 23 call channels. A single T1 Data line with SIP can handle about 18 call channels running G711, 37 channels running g729<br />

<br />
Fair enough,<br />
<br />
In regards to the the diagram discussed earlier:<br />
<br />
Telco Lines -> Gateway T1 -> SIP Proxy -> Media Servers -> Customer<br />
<br />
I understand that a T1 Gateway that has 480 channels, can handle up to<br />
240 calls.<br />
That is more than enough for the "Gateway T1 -> SIP Proxy" part of<br />
the diagram. I just<br />
want to make terribly sure I understand the "Telco Lines -> Gateway<br />
T1". If the Gateway T1<br />
plugs into only 1 FXS port, is that FXS port only capable of handling<br />
2 channels,<br />
i.e., one call?<br />
<br />
Thanks in Advnace,<br />
<br />
Nick.<br />
