Hi Darren,
Failover (hot/standby) is a good solution within one site. Use
heartbeat for that. You do not really need multiple servers for load
balancing unless you traffic goes beyond what a box can handle.
Failover for multiple sites needs backend replication and/or SER
replication.
I have a 2x2 setup in two sites.
If you need support to set this up you can contact me offline.

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,

Hi All,
I am getting this error while trying to load ser.
Any ideas on this.

I have added lookup("aliases"); in the ser.cfg but I still get the Error.

I got this error also when testing the CVS version. I had no aliases or
users defined an still got the error. I was able to get rid of it by
adding: lookup("aliases"); in the ser.cfg.

Hi,
I am writing a software to parse SIP messages. I have couple of questions that I would like to clarified.
1. How to recognise if a packet is a SIP or a non-SIP packet?. SIP uses TCP, UDP as underlying transport.
2. How to know the direction of the SIP message if it is from SIP proxy or from SIP client?. I ask this question because in most of the SIP messages, the header fields are copied from previous messages and so the from, To header fileds doesn't always signify he direction
3. Can Call-ID be used to find the number of distinct phone call taken place between different SIP UA's?.
4. What is the significance of dialog-ID? and how can it be used?
Thanks,
Balaji
I'm trying hard to get a handle on configuring ser but I think I need a few hints..
I thought I was doing the accounting right but the acc table never receives any information.. In my reading I thought by using setflag(x) where x was the same number as the db_flag number stateful accounting records would be automatic.. is this wrong..?
Can someone clue me in as to what I'm doing wrong as I just can't get this.
Here's my config if it helps at all:
