ITU Develops Modem over IP Standard (V.150.0 and V.151.1)

The ITU adopted a Modem over IP (MoIP) standard to ensure that as networks move to a ‘pure IP' infrastructure they will still be able to efficiently handle calls generated by dial-up modems. The new standards would also give end users the ability to carry on using their modems to the full extent of their capabilities on both circuit switched as well as packet networks. The two ITU-T Recommendations that deal with MoIP are V.150.0 and V.151.1. The technical group responsible for the specification was ITU-T Study Group 16.
