Why is it that not a single SIP handset manufacturer can come up with a way to do something that every legacy PBX system can? Our receptionist would love to be able to simply use the Phone at her desk (not the MyPhone App) to hit a Xfer to Voicemail button and then complete the transfer by hitting the BLF key for the user she's transfering too. Exactly the way our old crappy IWATSU PBX worked. But no, Polycom, Yealink, Aastra, Grandstream, Cisco, none of them think that this is a useful feature. How is it better to make someone have to hit transfer, dial a code, then dial the extension number then hit transfer? When every legacy PBX system can do this with TWO button presses? We should also be able to press an Intercom key, and then hit the BLF key for the user you want to Intercom/Page with. Why none of these phones/VoIP PBX's can put together two commands is beyond me. It really can't be that difficult to code it. This seems to be a MAJOR miss for the SIP market. And I don't buy the excuse that just because the legacy PBX systems did it that's no reason these SIP VoIP system should. Every SIP capable system should be able to do EVERYTHING the old PBX's could AND MORE! I hope 3cx can do something about this soon. But I have a feeling they are at the mercy of the handset makers.
