Scott Morris Enterprise Network Engineer DOE - ORAU / ORISE 865-576-4672 -----Original Message----- From: Morris, Scott Sent: Tuesday, August 10, 2004 2:29 PM To: serusers(a)lists.iptel.org Subject: 483 - too many hops error - 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.
