Hi,
Does SER support run-time configuration? For example, can we modify
the routing logic (like changing the destination to different PSTN gateway)
at run-time without restarting SER or effecting the ongoing sessions?
Regards,
Kevin

Hello,
no, it does not. You have to restart the server. On the other hand,
restarting the server doesn't harm that much, because it can be done
quickly, registrations will be not affected because they will survive in
the database and will be reloaded during the startup.
Regarding sessions, ser is transaction-stateful -- that means it doesn't
remember any state during the call, it keeps state only when a
transaction is active which usually during INVITE and BYE transactions.
If you restart the server during INVITE or BYE transaction (i.e. when
the server processed INVITE or BYE and is waiting for 200 OK), the
server will forward 200 OK statelessly so user agents will not notice
that. It may affect more complicated things like forking or accounting
on the server.
As you can see, restarting of the server is really not a problem because
user agents (even those in the middle of a call) will not notice that if
you do it quickly.

Hi,
How does the pa module work during the restart? Dose the subscription state
persist between restart?
Thanks,
Kevin

No, pa doesn't recover. Saving of pa state into database is on my todo
list, but with low priority.

I've got six phones registering to the
Same number. 5 work, the sixth is having
A problem. I see this in the log:
Aug 5 17:35:29 rave ser[21791]: ERROR: append_branch: max nr of
branches exceeded
Is there a configuration tweak to increase this? Perhaps a compilation
tweak?
Thanks

There is a compile-time maximum on number of branches in SER.
To increase it, update MAX_BRANCHES in config.h and recompile.

What do you mean by same number? Does it refer to an FXS device with FIVE
lines? On the same IP address?
Thanks

No, it doesn't per se, but you can arrange something like that by
placing routing decision on some third-party, for example we are using
radius server for this (propiertary extension). I believe that it is
also possible to do it with the help of database. In any case it is
trivial to write a module which will take original uri as a parameter
and rewrite it ising information from some external source such as a
database.
