Thanks to serendipitous timing on tensai's part, I learned today that OpenSER version 1.2.0 was released just yesterday. It looks exciting; a few of the most fundamental problems with SER have finally been fixed. Number one on this list is script variables. Now you can do:

$ruri = "sip:" + $from.user + ":" + $to.domain;

Second on the list is that you can now "extend OpenSER functionality by writing Perl applications to be executed embedded in configuration files." Other wonderful things:

• Pseudo variables can be used directly in the script
• Pseudo variable transformations
• DNS NAPTR/SRV failover
• An XMLRPC management interface
• XMPP (Jabber) Gateway
• SNMP
• LCR database caching

All in all, it looks like an exciting release. If (Open)SER disappointed you in the past, now might be the time to look again at OpenSER.
