Hi Alexandru, Well the concept is simple: on INVITE, you will issue a special format evapi request. You will receive the list of suppliers in the reply (which is received in a separate route) and you continue processing from there. These suppliers are simple tags so your creativity will be the limit of what you can do with them - eg: direct ip addresses received or tags of suppliers which you can further translate with drouting module or any alias related one. For more information on LCR please find this year's presentation on Kamailio World (which I strongly recommend to be attended): https://www.youtube.com/watch?v=Hsvcwleb-fY You can also find the kamailio configuration which I have used in the worshop here: https://github.com/cgrates/cgrates/tree/master/data/tutorials/kamevapi/kama… Let me know if further questions (or join our irc or mailing list so we do not create too much noise here).
