[asterisk-users] List delays

[David Boyd]

Walter,

I know you just said that list users can not help with this problem,
however I must beg to differ with you. The information that you just
provided is a big help, if people take your advice about the
configuration of their internal systems. So in one way it is off the
topic of Asterisk, but is on target for helping people solve their
issues if they interact more efficiently with the list and the resources
that it provides.

IMHO,

Dave
