[asterisk-users] Sort of OT: PBX vs CO

[Alex Balashov]

The other issue is scale.  A single Class 5 switch shelf can take many 
DS3s, and even several OC-Xs.

Asterisk can take... what, a few T1s?  Maybe?  That's nice.  And entirely 
worthless.  Someone is going to have to make it possible to take at least 
a few DS3s in a PC before something like Asterisk + SpanDSP + whatever
can work as any kind of "softswitch."

And, as has been mentioned already, SS7 is the other big problem.  And 
OpenSS7 only supports--to the extent that it supports anything--ISUP at 
this point.  Again, nice, but by itself abysmally worthless;  a modern 
switch needs TCAP for LNP and LIDB and a whole host of other capabilities.
