In its simplest form, ipDTL connects one computer to another, giving 2-way audio between web browsers, using the wideband low delay Opus codec.
SIP is the protocol for connecting between studios, which has replaced ISDN. ipDTL includes SIP calling as standard. It can also make phone and ISDN calls.
