hi, I have a user with extension 5469 and base id 8032. He is using an avaya 1608 H323 phone. I would like this extension to be on a new phone Avaya J159 (sip extesion) base id 8088 extension 4205. How can I do this in IPOffice 11? I thought I could just switcht the base id, but I don't think that would work if one is h323 and the other SIP. Thanks for your help.
