Currently our service provider installed 2 set of ONU modem which is responsible for sip trunk. each modem has wan ip to add it as trunk host (eg . 10.xx.xx.xx) . on the other hand, we have another router which used for Internet purposes which used by extension user , freepbx box and other servers (192.168.1.xx). Now because of the 2 set of sip trunk modem and the internet modem is different network. how can i make the freepbx box and 2 sip trunk router to listen each other.
I have searched and found that i can configure SWITCH by creating 2 vlans and connect them together. is it possible that way? or any other better suggestion i could get?. Thanks
