i don't understand it. serctl moni shows 483 whenever i use the Cisco [sip
fw v6.1] phones. 
i changed the display name on the phones to match the phone number, just in
case that was problematic.

the call as shown in the dump [that is only part of the dump, the full file
is 48 pages in word :/] results in:
a) phone A calls phone B normally
b) phone A is hung up, phone B sees the hangup and disengages [i can see the
screen on phone B change as if call was cancelled]
c) phone B immediately starts ringing again, thinking it is receiving the
same call again.
d) serctl moni notes 483 errors, and the 'Failure' count goes up as well.

X-Lite, MSN, and Kphone clients seem to work ok.

a tail of /var/log/messages shows the same message repeating [a summary from
sl_reply won't send reply for Ack

check out the ser.cfg, this is the one in use right now. it is nearly stock,
just a couple edits that shouldn't make much difference!?
