Ill be more specific.
1)I have a pri at a colocation so the line build out is less than 100ft.
2)Ive tested using the 1004hz test number to calibrate my rx and tx gains
correctly.
3)I was using a te110p and I am now using a te406 with one pri on it so thats
60ms of echo can per channel done by hardware. Which seems to have changed
nothing changing the card :(
4) ive monitored things with ztmonitor (although not a reliable tool)
to see if
any audio is to low or spiking to high.
The issue is with echo, its inconsistant sometimes works sometimes not but is
vastly more conistant and apparent on 905 area code numbers(905 covers some
local and some minor ld neighbouring cities) and cells than local 416 numbers.
ive even got echo on a phone line calling in 5 blocks away :P
It happens occasionally on either end.
I have been fighting 8 months with this trying to perfect it. but it
just seems
impossible hence my reasoning in to the questions is there such things
as dodgy
pri's or pris with echo on :)
Ive also routed calls through a 3rd party sip provider which never yeilds echo
some thoughts are the tap settings are incorrect.. ive tried all of
them with no
change if not made things worse. So its got to be something to do with the pri
right?
I know latency on connection is not an issue ive been as low as 13ms to the *.
Bandwidth is not an issue as its on the backbone at a colo.
Any light on this would be greatly appreciated.
Thanks.
Phil.
Quoting Jim Van Meggelen <[EMAIL PROTECTED]>:
It's not the PRI that's echoing, it's the far end that's echoing back to
you. You just get to hear it.
It is more common than we'd like, and is one of the reasons why everyone
(Sangoma, Digium, Rhino) is bringing hardware echo can cards to market.
Jim.

Has anyone ever experience echo on pri's?
Is there such thing as a dodgy pri?
Thanks
