I'm afraid that I don't quite understand. How does this solve the problem?
I'd actually like to do load balancing between two servers, but in order to
do that then I would need for the SIP phones to be able to register with
server #1 and have server #2 be aware of the registration on the first
server. Otherwise calls for that phone that are destined to server #2 will
not find the phone in it's local userloc table and will send it out to the
PSTN gateway.
Thanks,
Darren

Hey All,
I have sent this question once before, but I don't believe that I received a response back. If so then I appologize as I must have missed it.
Could someone help me out with this? We are gearing up to launch SER on a large scale but I want to verify that I can have multiple SER servers in a primary / failover scenario before doing so.
Can I put SER onto multiple servers with load balancing and share the userloc tables between the servers (ie. With MySQL or Postgres SQL)
Is this possible? Or does one SER instance only recognize registrations for phones that register with that particular instance/daemon?
Thanks,
Darren Nay - dnay(a)libertyisp.com
This is what I get.

if you are sure that the new nathelper module works with the version of SER you
got,
cd sip_router_latest/modules/nathelper/
make clean
make
# if everything goes ok, nathelper.so will be created.
cp nathelper.so /usr/local/lib/ser/modules/ (take a backup of the original
/usr/local/lib/ser/modules/nathelper.so in case anything goes wrong).
dhiraj
you have to download the complete ser tarball from CVS and not just the nathelper module tarball.
and then try again.

My config file is below. When I am trying to start ser I get a bad config file 4
errors?
Any ideas's on that?
