Under management of Elena-Ramona Modroiu, the project was developed so far by Asipto - - using OpenBiz PHP framework — the target was to make it easier to extend for non-web developers. Soon, the project sources will be hosted on SVN (project name: siremis).

  • subscriber, database aliases and speed dial management
  • location table view
  • dispatcher, prefix-domain translation and least cost routing (lcr) management
  • access control lists (user groups) and permissions management
  • accounting records, missed calls and call data records view
  • hash table, dial plan table and user preferences table management
  • off-line message storage view
  • it was tested with MySQL but should support other sql-like DBs

Internal design:

  • developed on top of a framework: PHP/Web2.0/Ajax
  • XML Metadata driven extensions

Send SIP Messages From Config File

You can initiate SIP messages from Kamailio (OpenSER) configuration file ...

uac module provides a new function that allow sending sip requests from configuration file:

- uac_send_req()

It opens the door for a new bunch of things you can do now. I can think of now:

1) send IM alerts on special events

route { 
$uac_req(ruri)= "sip:alert[at]";
$uac_req(hdrs)="Content-Type: text/plain\r\n";
$uac_req(body)="SIP request from:" + $si + ":" + $sp;

2) turn lamps on for some sip phones on some events - e.g., snom:

3) talk server-to-server - here one example can be building a platform with a central server for accounting. Accounting is done at 200ok. So each routing server will build a csv list (time,callid, from tag, to tag, invite from uri, invite r-uri):

onreply_route[1] {
  $uac_req(hdrs)="Content-Type: text/accounting-csv\r\n";
  pv_printf($uac_req(body), "$TS,$ci,$ft,$tt,$T_req($fu),$T_req($ru)");

note that $T_req() is given by tm module, also with Kamailio trunk:

The accounting server:

  # you should check the source IP also
  if(method=="ACCOUNTING" && $rU="store")
             "insert into accounting(timeval,callid,ftag,ttag,src,dst) values ('$(rb{,0,,})','$(rb{,1,,})', ...)",
      send_reply("200", "Stored");   

... and you can put your imagination work ... there are plenty of new and cute features you can add on your service with this functionality ...

The Kamailio (OpenSER) project approaches the time for a new stable version:

There is a lot of new development since last major release 1.4.0, check a summary at:

AFAIK, before release, 2-4 new more module are going to be introduced and couple of existing modules extended. This is a notification for all users and developers (existing or upcoming) to finish the work before the freezing date if they want to get their code in Kamailio (OpenSER) 1.5.0.

The 1.5.x series will be the last to use the current core. Next releases will be based on SIP Router project:
