Hi, one nice thing about voip is making free calls to other user having their own SIP URI. Image the following setup: - several hard and softphones are connected to a 3cx system - there´s one Mediatrix voip gateway for incoming and outgoing landline calls. - For outgoing calls to landline numbers, users have to to add a "0" before every actual number. - ... There are many SIP based external service, e.g. conferencing. What I´d like to have is: I want my users being able calling SIP-URIs from their e.g. hardphones, so instead of typing a number they dial sip:email@example.com So the phone basically takes this and gives the SIP URI to the registrar, which is in this case, the 3cx voip server. Next thing is that the server has to deal with this within the dialplan. Is this possible with 3cx? How can this be enabled within the dialplan?
