[asterisk-users] Fast Busy

[Rob Schall]

We currently have a pri coming into our asterisk system. Most of the
time, the did numbers that we call into it work great. However,
occationally, we get fast busies, but we noticed those busies were not
due to anyone being on the line, etc...

Any ideas what could cause this? Is this a congestion thing? Is there
something I should add to the dial plan or configuration of the card to
fix this?

Thanks,
Rob
