Is it possible to call out to a skype contact that does not have a phone number (by just using a username or something)? Incoming Skpe calls from said contacts works wonderfully, but I have no way of calling them back nor placing a call to them. Is this a supported feature? I am just looking to send Skype calls to my desk phone, I do not wish to place calls to the PSTN through it, as I have a SIP trunk from CallCentric for that. Thanks in advance for the help.
