I found documentation on the 483 - too many hops error and what to do about
it, but I guess I don't have a handle one the concept, just like many others
I guess. Here is the information I am using.
Sign-in name - morriss(a)orau.net
username - morriss
password - xxxx
my workstation is 10.5.10.1
SER server is 10.0.2.1 (
comm01.orau.gov)
the sip service records for dns are
comm01.orau.gov
SER version - 8.12 running on Redhat 3.0 ES
workstation software - Windows Messenger 4.7.2009
Please take a look at the ser.cfg and ngrep below and see where I have the
uri not set properly. And can more detail be provided on the aliases
command?
Thanks.
