This one confounded me for a while as it comes up on the occasional RFP and other PBX vendors are known to handle it well.
The scenario is as follows: You’ve answered your call on your mobile device using VoIP, but you’re now back at your desk and want to use your Lync or Skype for Business desk phone.
If it’s a conference call, you can just rejoin the conference from another endpoint, but for a one-on-one call, I didn’t think this was possible as you can’t easily park the call and there’s no obvious other way to accomplish it.
Simply transfer the call to your own Skype user. The mobile client will notify you that it’s transferring the call, and you can pick up the call on another endpoint. The calling party may potentially hear hold music so it’s not seamless, but it’s an option.
If the call is not a VoIP call and you’ve answered the call using your cell service, this functionality does not appear to work that same at this point, at least from an iPhone. If you can transfer the call from your cell phone, that would be your option there.
If you’d like to see this feature more properly implemented; please vote for it here: http://www.skypefeedback.com/forums/299913-generally-available/suggestions/13798731-move-audio-from-any-endpoint-to-another-seamlessly
There are other feedback requests that say similar things, but with few votes or not quite the same. Please vote it up, this feature would be huge.
