[Serusers] voicemail config

We support multi-ser instances per machine.
We use ipaliases, eg:
/sbin/ifconfig eth0:0 10.2.1.10 netmask 255.255.255.255 up
/sbin/route add 10.2.1.10 dev eth0:0
we then make a directory:
mkdir /tmp/ser_fifo
Then the top of each configuration file:
debug=2
log_stderror=no
listen=10.2.1.10
port=5060
children=4
fifo="/tmp/ser_fifo/unique.com"
alias="unique.com"
alias="proxy.unique.com"
alias="nat.unique.com"
alias="10.2.1.10"
Then start the thing with
ser -f unique.com.cfg
where unique.com.cfg is the file above...YMMV
unique.com is not a real site, just a name placeholder...
If you are using mysql you will get TONS of dbopens, the
old postgres also does TONS of opens. I hacked my SER to
wait on the dbopen. I've attempted a couple of times to check in
the hacked code but always run into problems (operator I'm sure).
I can send you the modified postgres code if you are using that,
otherwise, there may be an issue with the number of open db connections
if you start more than a couple. I currently have about 8 ser instances
running on a single box, with only 16 db connections between them.
My experience with multiple servers on a single box has been mixed.
The main thing is debugging is more difficult. You have to capture
traffic from the lo (loopback) interface as well as the ethernet
interface, looking at two ngrep traces can be confusing.
I like to use tcpdump or ethereal to capture and look at sipscene
traces, this is impossible with loopback. I have
tried everything to merge (tethereal, mergecap, etc) a loopback
capture and a ethernet capture, they don't mix!
What I ended up having to do was put servers on separate boxes
so I can capture the traces to debug! So I keep:
external servers (inbound/outbound pstn/sip/enum) on a set of boxes.
external interfaces (proxy/registration servers for customers) on a
set of boxes.
voicemail / media servers on a set of boxes.
I then use a cisco switch/port monitoring to give me a sniffable
feed to do packet traces. I highly recommend getting traces to work,
otherwise, debugging is a major pain!
Good luck,
