I have (1) DP750 base station and (3) DP720 handsets. I pay for and use just one SIP account/phone number for the DP750. I want to be able to transfer a call in progress that’s being handled on one of the handsets over to another of the handsets. The only way this would be possible, presently, would be if I were to buy two additional SIP accounts and dedicate all three to the handsets individually.
That’s a problem because that triples my cost for SIP service. Why can’t the DP750 and DP720 software include a feature that lets you transfer a call in progress on one of the served cordless handsets over to another of the cordless handsets being operated by the same DP750? Of course, you wouldn’t be able to specify the other handset to send the call over to via a SIP phone number, because all three are being served with the same one. But, you could simply identify the other handset some other way. Say, by a single, unique digit assigned to each of the three, just for that purpose. And you use some menu/command button sequence on the handset to initiate the transfer, in the same type of manner you’d otherwise transfer a call to another SIP account/phone elsewhere on the network. Call it an ‘internal’ transfer for the DP750, if you like.
Does that make sense? I can’t imagine many customers haven’t proposed this already, many times. WHat do you say, Grandstream?
