VoIP applications become popular in recently years, and more and more network researchers are interested in VoIP issues. However, users are used to using the traditional telephony number to make calls. This is because the telephony number is more convenient than the meaningless IP address and the diffusive domain name in VoIP networks. They are really hard to remember.
In this paper, we discuss the design and implementation of ENUM (tElephone NUmber Mapping) service over a SIP user agent. According to the technology of ENUM (RFC2916), the dialed numbers can be encoded into E.164 numbers. By querying the DNS, we can get the SIP URI (Universal Resource Identifier) which exists in the NAPTR (Naming Authority Pointer) resource records. The ENUM service plays an important role between the traditional telephony networks and the VoIP networks. The users can be unaware of the different operation style in VoIP.
