I have not followed the thread so don't know if this is releveant.
I think you should not put the sip: prefix in the alias option of your
config file.
Hope it helps,
Samuel.

Hi Marian,
I carried out the test you suggested and the message
printed out in /var/log/messages, so I still have the
483, too many hops error. Therefore the client uri
definately matched the domain part of the sip url. As
mentioned previously I change the domain in /etc/hosts
on the ser machine(and also added the gateway),I added
the dns address in /etc/resolve.conf and I also edited
the address in /etc/profile.
Therefore at this stage I dont think its the
domain....at least i dont think so anyway...I have
checked that ser is listening on the address specified
with the specified port using netstat -tunap and it is
running.
When I sniff the loopback interface on ser I see tht
the invite message is repeatedly issued to the ser
machine. The sequence for this was shown in the first
email.I have included my default config below (its
pretty basic) and any further thoughts would be
appreciated. Both clients and ser are on public ip's.
Kindest regards,
Pat

Hi Pat,
do some small test - add at the beginning of your
script:
if (uri==myself) {
log(1,"uri is myself\n");
};
and see if you get that message in ser output/logs.
Just to be sure that
myself test is passed.
Best regards,
Marian

The domain name is the ip address of the ser
server
i.e. a user registers as 2001(a)xxx.xxx.xxx.xxx.
Therefore I set alias=xxx.xxx.xxx.xxx in my
ser.cfg.
