Hello , i am a professor of telecommunications at the Catholic University of Chile. For several years we have implemented freeswitch and asterisk as learning platforms for IP telephony in this institution. Eachother 've got a donation from a trunk sip , but it uses Elastix 2.5 as a platform. We have not been able to connect to them through a SIP trunk , and we are looking for your help. Unfortunately we have no money to give them a payment to you for the support; We have followed this tutorial does not work
https://wiki.freeswitch.org/wiki/Connecting_Freeswitch_and_Asterisk . Please , if you have a guide on how to connect with Elastix 2.5 freeswitch we would appreciate your advice and information .
Thank you.
