It's going to be a custom routing module, with our own business logic. It should load the routes from a database and keep refreshing the data every x interval. For SIP-to-PSTN calls (outgoing to carrier) we need to be able to route based on the callerprefix, customer id (which is added as a custom header), originating IP, and some other fields. I need a way to select the closest matching route, or fallback to the default route, using the fields described above.
Implementing this logic in a stored procedure is quite hard. Another option would be to write a web service and perform http calls to determine the route. I'm just worried that http might delay the setup of calls. Our routes table contains custom fields, but also fields which are used by the dispatcher module. So once a route is selected, the dispatcher module will use the uri in the route set to rewrite the ruri and possibly do failover. -----Original Message----- From: sr-users-boun...@lists.sip-router.org [mailto:sr-users-boun...@lists.sip-router.org] On Behalf Of Alex Balashov Sent: Tuesday, August 20, 2013 12:43 PM To: sr-users@lists.sip-router.org Subject: Re: [SR-Users] Writing a module On 08/20/2013 06:41 AM, Grant Bagdasarian wrote: > Hello, > > Is this page still up-to-date: > http://www.kamailio.org/dokuwiki/doku.php/development:write-module ? > > I'm researching what it takes to create our own custom Kamailio module. 1. Skilled C programming. 2. What do you want to accomplish? Are you sure no combination of existing modules and script constructs fit the bill? Sometimes you really do need a custom module. But I find those cases to be relatively few, at least for applications of Kamailio that are not truly exotic. -- Alex -- Alex Balashov - Principal Evariste Systems LLC 235 E Ponce de Leon Ave Suite 106 Decatur, GA 30030 United States Tel: +1-678-954-0670 Web: http://www.evaristesys.com/, http://www.alexbalashov.com/ _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users _______________________________________________ SIP Express Router (SER) and Kamailio (OpenSER) - sr-users mailing list sr-users@lists.sip-router.org http://lists.sip-router.org/cgi-bin/mailman/listinfo/sr-users
