I am working on voip setup. I am configuring just outgoing call legs. Means, one pots dial-peer for the pbx that is connected with router through pri and others voip for remote destination. I am not configuring incoming legs with "incoming called-number". Everything is working fine. But i need to know that in a big voip setup with 25 sites what you recommend? Is it good with configuring incoming call legs or it is just ok without them?
