10. SIP Trunking is only the Beginning “To date, SIP trunking has been largely focused on recreating current TDM voice services (“trunks”) over IP. While useful, that’s only one possible use. We see the true market potential of SIP trunking in its ability to act as a hosted services “conduit” and to carry media other than standard PSTN quality voice – capabilities impossible with TDM.” - Broadsoft
