Strange. You should watch the network traffic also on the loopback interface. (ethereal supports this). you can send me the dump file from ethereal.

I think the alias must be in one line, or only the last line will be used!

from your dump: the proxy forwards the invite to the second phone - which does not answer. There is no 483 in your dump.

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 memory]: 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!?
