That is correct.

I would suggest you investigate this further, as we have seen this also
in Germany where the called-party disconnects, but the disconnect is NOT
sent to the calling end for a few seconds. The MAX did not know the remote
end had disconnected.

I don't think it's the MAX "holding on" to the call - but the call disconnect
message is being delayed on it's way to the MAX.

No, but I thought that:

                Ascend-Expect-Callback = Expect-Callback-Yes,
                Ascend-Send-Auth=Send-Auth-None,

would have had the desired effect. I did think that this tells the MAX to
drop the
call from this end when 'authenticated' - which *may* be the secret....have
you
tried making the MAX authenticate to the remote end with:

                Ascend-Expect-Callback = Expect-Callback-Yes,
                Ascend-Send-Auth=Send-Auth-PAP,

for example?

I guess while we investigate this, you may want to do that. Unless the
authenticate trick works....I'll check into it more here.
