Kamailio (OpenSER) v3.1.0 is out – major release with impressing number of new features and improvements.
On October 06, 2010, Kamailio (OpenSER) 3.1.0 has been released – this release is a result of more than 8 months of development from the teams of Kamailio (OpenSER) and SIP Express Router (SER) projects. Backed up by a solid development group, we are proud to announce that this release brings a large set of features, many for first time on the SIP server market, such as asynchronous TLS, UDP raw sockets, embedded HTTP and XCAP servers, embedded Lua, configuration file debugger. All together, there are over 15 new modules and countless improvements to old components.
Since last major release (version 3.0.0, which was out in January 10, 2010), the two SIP servers, Kamailio and SER, are practically the same application, the name making the difference regarding the database structure and the extensions used for certain features, such as user database based authentication or location service. Therefore another development direction was towards smooth integration of Kamailio and SER extensions, previously duplicated modules such as auth, sl, ratelimit or sms were merged during this development cycle.
Continue reading the release notes at:
#!define DBURL "mysql://openser:openserrw@localhost/openser"Changing access to database requires now to update a single place, the define of DBURL.
...
modparam("auth_db", "db_url", DBURL)
#!define MYLOG xlog("[$Tf]: message $rm from $fu to $ru\n")
...
route {
...
MYLOG;
...
MYLOG;
...
}
...The new subst allow replacement inside string values - example: replace DBPASSWD token with 123qaz in all strings inside configuration file:#!subst "/DBPASSWD/123qaz/"Note that defines and subst apply to all parts of configuration file, not matter are global parameters, module settings or routing blocks.
modparam("acc", "db_url", "mysql://user:DBPASSWD@localhost/db")

Kamailio 3.1.0's new module named geoip provides to configuration file an easy way to discover the location of caller or callee based on IP address. You can query a Max Mind GeoIP database and receive location details such as country code, time zone, a.s.o.if(lookup("location")) {
# callee is online
geoip_match("$si", "src");
geoip_match("$nh(d)", "dst");
if($gip(src=>cc)==$gip(dst=>cc)) {
xlog("caller and callee located in same country - code: $gip(src=>cc)\n");
}
}
Another beneficial result is to be able to drop traffic coming from specific countries that tried to attack your service or you don't have customers. This is very useful these days, in a time where spit and scanning attacks against VoIP server increases.geoip_match("$si", "src");
if($gip(src=>cc)=="CA") {
xlog("SIP message from Canada (ip: $si) - drop it\n");
send_reply("403", "Forbidden");
exit;
}
GeoIP API is very easy to use, the module has one parameter to set the path to GeoIP database, then you can match any IP address (e.g., source IP, next hop IP, IP from Via, Contact or any other header) and store the results in as many containers as you want, then they can be used to compare any attribute between them or against config values.
