I am looking for a way to limit the number of simultaneous calls that a given user can
establish thru ser at a time. I realize of course that any options would require stateful
use of ser but that is already a requirement in this project.
Thanks for any insight

That's not possible for the reason you mentioned.

You may be able to use an external workaround. If you use radius
accounting, and a radius server, such as radiator, which lets you create
your own "session database" in an SQL table, based on the START/STOP
accounting messages.
It would be a lot of work, but in your outgoing call processing, you
could use one of the radius_uri functions, to have the radius server,
check the session DB, and allow/deny it based on that.

After a few discussion with some colleges, although it would not be a simple
task, we feel it would be possible to maintain a table that would allow one
to limit calls on a per registrar basis by either using the table you are
creating in memory to support statefull transactions currently or creating a
seperate sql based approach. I might even have a programmer who would be
willing to put in some time on this for the project but the it lead me to
remember my days of RAS/Radius Authentication. In the early days we had
problem with lost radius accounting info caused by a crash or packet loss.
This would leaving users locked out because of connection limits set on the
radius profiles. Of course the answer was to start polling RAS's via snmp.
This allowed us to clear bad data periodically from the radius connected
users table. Along these lines I starting looking to see if there was any
type of status messages or request that could be sent at a UA to verify it's
call status and the only thing that I came across mention of session timers
but I get the impression that some issues exist with support for this
feature and not much energy is being placed on this because of that. Well,
all this being said I would appreciate and input/direction in how you would
like to see Call Limiting on a per user basis become a reality.
Thanks

I personaly think it is more interesting to encourage making calls rather
than banning it.
Nevertheless, if you wish to ban calls based on user's status, then you
must remember it somewhere. A simple possibility is to write a call
stateful module which will keep a list of calls in some table. New calls
will appear in the table (best inspiration can be imho found in the
accounting module), all new call attempts will be checked against it.
To make sure that dead phones will not result in calls which are never
terminated, you may wish to configure SER to use session timer. If the
party, which understands session-timer, is still alive it will be able
to detect the other party is dead and terminate the call. That's mostly
ok -- people typicaly deploy all kind of limitations for calling to
PSTN gateways and they are comfortable with delegating the accuracy job to
them.
If you don't wish to rely on accuracy of UAs, you may wish to write
a B2BUA on your own. Such a server will then keep track of call and
will be able to terminate it on its own. That's however quite some work.
