There are plans to package sip-router, when it will reach some level
of quality, since it's a merge of SER and OpenSER/Kamailio. Also,
there is an attempt to package OpenSIPs (another one fork of
SER/OpenSER codebase) - take a look here:

1.3.4 is the last stable version of OpenSER. Since ver. 1.4.0 it was
rebranded as Kamailio.

A lots, actually. There are some changes in config-file syntax, in
plugins and so on. Every version of OpenSER/Kamailio
(1.3.x/1.4.x/1.5.x) is incompatible to some degree with previous one.
Fortunately, they can be installed in parallel due to different naming

The curse of this project is the team/features management issues,
which led project to the number of consequent forks (and one merge),
which confuses end users a lot. One of popular questions from
customers, is "which one from these routers should we choose -
SER/OpenSER/OpenSIPs/Kamailio/SIP-Router?". I'm voting for OpenSER
1.3.4 right now - it's stable and it was proved to work reliably.
Perhaps, at 2010, we may consider switching to SIP Router.

With best regards, Peter Lemenkov.
