In this paper, decoding of the ISUP message has been presented. Since the IP telephony industry has strongly embraced SIP, itâ€™s necessary for conversion between ISUP and IP to have compatibility with the existing networks. Now-a- days, itâ€™s still very much in the developing phase. The potential problems exist when the soft switch network provides a transit function between PSTN and SIP based VoIP networks. The soft-switch (SIP <--> ISUP) approach will be the best choice for smooth migration to the Next Generation Networks.
