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:
localhost*CLI> sip debug peer 1004

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.
