[SR-Users] Kamailio-Java Integration

[ron.kamailio at mcleodnet.com]

I am the OP.  I actually have a solution running now, using JSON-RPC as the
connector between Kamailio and the Java EE business logic.  I am looking for
an alternate solution to resolve the limitations with the RPC mechanism.
Performance is not an issue at all.  In-fact performance is barely a
consideration for this application -- busy hour traffic is around 5
transactions per second, with the majority of the transactions being SIP
MESSAGE request/response.

While SIP requires sub-second precision, it does not require millisecond
precision.  :-)

In any case, garbage collection is definitely a problem, but there are ways
of optimising the JVM's GC behaviour to be more or less favourable to the
task.

That is definitely true, though one might argue that this is a cultural
problem rather than an innate Java problem.

In any case, I am not a Java programmer and am not defending Java, so please
don't misconstrue my stance.  I'm just saying that it might not be _wholly_
unsuitable to the task.

I do not think, and have never thought, that Java is an ideal language in
which to implement SIP call processing.
