Hi all, A statement I quite frequently come across when proposing the sale of a VoIP system to potential customers is: I'd like to go VoIP to save call costs, but i'm sceptical over the call quality With that (and customer satisfaction) in mind I would architect a system which is VoIP on the LAN (i.e. 3CX) but which has a VoIP gateway to take trunk calls over the PSTN. In terms of migrating the customer to a VoIP solution I would aim to take a pragmatic approach and add in a VoIP provider trunk and slowly migrate a chunk of their calls from one medium to the other until they are happy with VoIP's performance. My question is - is there a way of automating the migration to VoIP such that the VoIP trunk is monitored for performance and switched to PSTN if perfomance is seen to be degrading? If not, does anyone else think this would be a viable feature request or are there better methods of achieving this i'm missing? Cheers, Mike.
