There are probably echo suppressors on both ends of the LD circuit between NJ and CA, but none on the local NJ circuit.

Not a silly question. I've given that thought.

To be honest, I'm not sure what kind of phone the California or NJ
callers were using.  However, we've had numerous conferece calls using
many other services and have never had echo problems.

The problem, in this case, more likely has something to do with the NJ
leg of the call (call 2), and possibly my leg (I was caller 1), since
the echo happened when it was just the two of us.  If anything, the
"problem phone" would be my phone.  This is a Lucent Partner phone
system and phone.  Now, if it was MY phone causing the problem, then
both caller's 2 and 3 should be hearing their echo.  But they weren't.

I'm stumped.


For anyone who's trying to figure out how I'm doing an E1 PRI here in the US, it's working like this:

Verizon T1/PRI  -->  Cisco VCO/4K (Programmable switch)  -->  E1/PRI -->
MyAsterisk

The other 2 calls are going like this:

888 number --> SS7 --> VCO/4K --> T1/PRI --> Asterisk_1 --> IAX -->
MyAsterisk
