Hello YiannisH. I have a trunk between two pbx and one Inbound Rule To forward Call to External number. I have too an Outbound Rule. Could tel me how to config step by step?Hi @JSimao
What you will need is either a SIP Trunk between 3CX and the other PBX and an outbound rule to send calls from 3CX to the other PBX.
So connect the 2 systems using SIP trunk (It can be an IP based trunk without authentication). Then when an inbound call comes into 3CX you can use inbound rules to transfer the call to an external number which will be the other system. You will need an outbound rule to do that.
Founded in 2005, when VoIP was an emerging technology, 3CX has gone on to establish itself as a global leader in business communications.
