Do you happen to have the URL address for IETF ? * A user calling from a "net phone" would use a host name in the form 7.9.3.3.6.2.9.3.2.7.9.tpc.int to call the phone number +972-3-9263397 belonging to a "regular" PSTN (i.e. domain name is The manner that you are suggesting will be hard to use for the end user. Which will prefer to enter the DN and let the system’s network management to the resolving work. It might be the case for the universal IPNP system to behave in the manner that you are describing, but the end user still need a simplified way to enter the DN. ---------------------------------------- Eng.

And there is already a possible solution to the problem, outlined in the RFC 1530 (Principles of Operation of the TPC.INT Subdomain). This is, of course, my personal view of the matter and just one more idea on the solution to the problem. * A user calling from a "net phone" would use a host name in the form 7.9.3.3.6.2.9.3.2.7.9.tpc.int to call the phone number +972-3-9263397 belonging to a "regular" PSTN (i.e. domain name is the reversed phone number, much like IN-ADDR.ARPA system). In the DNS, there should be an "MX" record pointing to the PSTN/Internet gateway, e.g.: *.*.*.*.*.*.3.2.7.9.tpc.int. IN MX 10 pstn-gw.domain.com. The client application should consult the MX records, find out the name of the gateway and then connect to the gateway - the same way mail clients do. * A user calling from a PSTN should probably use an access code to reach a local PSTN/Internet gateway - which is exactly the way you described. That access code should be assigned by a national telecom authority.
