Explanation:
SIP trunks for public switched telephone network (PSTN) access are an important new access
method for business collaboration. Service providers throughout the world offer SIP trunking as an
alternative to traditional TDM (T1/E1) connections.
A discard digits instruction (DDI) removes a portion of the dialed digit string before passing the
number on to the adjacent system. A DDI must remove portions of the digit string, for example,
when an external access code is needed to route the call to the PSTN, but the PSTN switch does not
expect that access code
