i attached one ser.cfg file. and a dump file from ngrep. it looks like a bunch of INVITES. the Cisco phone B rings, but if i hang up Cisco phone A, B continues to ring and ring... and 483 errors every few seconds, what a mess.

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.

No, they can be on one line or on multiple lines or in any combination. E.g.:
alias= foo alias= bar
is equivalent with alias= foo bar
