hi-
I am looking into using SER as part of our test infrastructure for a
SIP-based messaging system and have 2 questions: one about SER
capacity, and one about the best way to configure it. Firstly though,
the setup:
We use a script-driven inhouse SIP/RTP test tool in association with
our messaging system which can either send or accept SIP invitations
and process the associated RTP streams (eg act as UAS or UAC). This
tool has a capacity of ~125 ports.
We need the messaging system to create around 800 concurrent SIP/RTP
sessions (dial out), and our system allows only one outbound sip
gateway. I therefore need to configure a sip redirector which can take
incoming SIP invites from the messaging system and redirect them to
one of 7 test tool clients (125x7 > 800).
First question, re capacity - the 800 concurrent sessions will be
staggered and spread over 2 minutes. This works out at about 7 SIP
invites per second. Should SER be able to handle this (proposed SER
box =2.8Ghz, 512mB RAM).
by far... Such a non-register, non-DB setup will (if you
don't proxy
RTP) handle more like 4-digit number of CPS :-D
Secondly, the Request-URIs of the SIP invites sent by the messaging
system are structured, and it is easy to tell from the Request-URI
which client machine we want this invite to be redirected to. Eg:
1000000000-1000000999(a)dom.com -> should go to client 1
1000001000-1000001999(a)dom.com -> should go to client 2
1000002000-1000002999(a)dom.com -> should go to client 3
1000003000-1000003999(a)dom.com -> should go to client 4
etc
Rather than registering all these accounts on SER, is there an
alternative way I can get SER to redirect various SIP invites using
wildcards to check the structure of their r-URI?
eg
1000000...(a)dom.com redirects to A
1000001...(a)dom.com redirects to B
1000001...(a)dom.com redirects to C
etc.
Yes:
if(uri~="sip:1000000.*@.*") {
rewritehostport("myserver","5060");
}
etc
g-)
Thanks for advice.
Tom
