Tried the syslog & debug, but it reports the exact same thing as the sip
debug shown below. It includes the INVITE, 100 TRYING, AND 486 BUSY
HERE. There are no hints as to why the Busy Here message is returned.
I was kind of guessing that something in the sip header was not as
expected for the device, but I don't see anything that seems to be
inappropriate in the sip debug.
Thoughts?

Need a little help trying to understand what's happening here.
spa941 -> Asterisk-A -> iax2 -> Asterisk-B -> spa942
When the spa941 (x3000) calls spa942 (x1004), the spa942 returns a "busy
here" sip message. The spa942 is not busy and does not have DND or any
other option set to cause a busy-here message. Asterisk-B is v1.2.10
updated to current svn. (Seeing the exact same issue with an spa3k.)
A sip debug from Asterisk-B shows the following three packets:

In addition, if I access the spa942 via a web browser, all lines/extns
are idle. Does not seem to be any reason for the 'busy here' message
that I can see. Placing a call to another spa942 on the same Asterisk-B
and on the same wire works fine. Yesterday the first spa942 was working
fine as well.
Can anyone see anything strange in the sip debug that would cause this?
R.
