Hi,
is there anyone who is not using SER in statefull mode (i.e. using
SER Accounting which you usually dont want to do) who did run into
serious performance problems using a modern multiprocessor system?
IPTel states that an compaq ipaq would be able to switch the bay
area during peak time, therefore i cant think of any scenario
(except some MAJOR carriers maybe) where most SIP providers would run
into critical load-balancing issues except with rtp-proxying. I am
quite positive that one can handle massive sip-request load by using
high-end machines with maybe several network cards.
Regarding the prepaid scenario, do u guys thinks its possible to
use an tcl script on a cisco to extract the timeout from a
custom sip header-line (ex. "X-Timeout: 320") inserted by a
custom SER module?
I do not know any method to access the SIP message in a TCL script. But
you can use Radius authentication on the Cisco box. The radius server
responds with a certain h323-attribute which will tell the Cisco box the
max call duration.
