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 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.

http://lists.iptel.org/mailman/listinfo/serusers hello List,
i am sadly aware that the 483 problem is covered in the
Admin guide & faq.
the solution as i read it is to replace if
(uri==myself)
with some regexp
for the sip proxy. but this is apparently not a
proper
implementation, from
what i have read on the list. furthermore, the if
(uri==myself) expression
is further down in the logic, below the check for
maxfwd
that results in the
483. if have set SIP_DOMAIN and added aliases to
ser.cfg. i
am sure i am
missing something small and simple...
my clients are cisco 7960 with sip fw v6.1.
