Thanks! Will have a look at it. I did try the LCR module with using the from_uri in the rules table, but the result wasn’t what I was expecting. Will play with it around some more, and after that try your suggestions! Much appreciated! ________________________________ From: sr-users &lt;sr-users-bounces(a)lists.kamailio.org&gt; on behalf of Emmanuel BUU &lt;emmanuel.buu(a)ives.fr&gt; Sent: Friday, February 2, 2018 5:34:02 PM To: sr-users(a)lists.kamailio.org Subject: Re: [SR-Users] Routing based on A and B numbers Really depends on what you want * carrierroute is great for prefix based routing but lacks multiple information output * if you want to use carrierroute on A and B, I would use it in cascade mode: first carrierroute call on A number, and use the result of the first carrierroute ($rd) as context for the second call B number. That is a kind of an elegant hack * I would use DIALPLAN for maximum flexibility with regex Emmanuel Le 2018-02-02 à 15:00, Grant Bagdasarian a écrit : Hi, Which module would be best suited for routing calls based on A and B numbers? We’re currently using the LCR module, with some additional htables to add this functionality, but I was wondering if there is a module which does exactly this? Or perhaps a combination of modules?
