In this paper, decoding of the ISUP message has been presented. Since the IP telephony industry has strongly embraced SIP, it’s necessary for conversion between ISUP and IP to have compatibility with the existing networks. Now-a- days, it’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.
