asterisk users - Sep 2003 - echo for 15 seconds

Hello,

I am running asterisk with two X100P cards using a cisco ata 186
"MGCP" for
phone connections.

For the first 15 seconds of a call I get echo on the ata 186 side only.  I
assume after that the echo canceller kicks in but is there any way to make
it happen faster?

I have read some stuff about this on the threads but didn't find the answer.

I appreciate any help very much.

Thanks
Chad

Same thing here - except we're using Cisco 7960 and 7940 IP phones.

We're getting used to it, the main thing is that the remote caller
doesn't
hear it (which they don't). A person visiting our office and using the phone
may get a bit of a surprise though.

Incoming calls it's not an issue, as the caller would have already gone
through the IVR/auto attendant and presumably the echo cancellation has
already kicked in before reaching the operator.

A related question for those reading this post - is echo cancellation an
issue with ISDN? I've thought of converting the POTS lines to a couple of
BRI lines - but if echo is still a problem then I'll leave it until we
actually need the extra lines.
