Thanks,

Do you have any experience (or know) where I can get some info on setting up an ENUM testbed with DNS and Linux?

Im interesting in experimenting with ENUM in conjunction with Ser and was

wondering if there is support for enum within ser.

There is ENUM support in the CVS version of SER (not yet in a stable release). We've been reported people used it successfuly.

Thanks Juha,

I'm building SER from the CVS archives and will test. Do you have any experience using any of the public ENUM servers, I believe there are a couple ENUM trials underway now.

if by testbed you mean running your own e164.arpa root, then you simply make your dns server a root for e164.arpa domain by adding line

primary e164.arpa e164.arpa.db

into your named.boot file and then by populating file e164.arpa.db with your enum entries. below is an example.

-- juha

------------------------------------------------------ $ more e164.arpa.db

$ORIGIN . $TTL 0 ; 0 seconds e164.arpa IN SOA foo.fi. hostmaster.foo.fi. ( 200204681 ; serial 28800 ; refresh (8 hours) 7200 ; retry (2 hours) 604800 ; expire (1 week) 86400 ; minimum (1 day) ) NS foo.fi. $ORIGIN e164.arpa. $ORIGIN 8.5.3.e164.arpa. $ORIGIN 9.3.8.1.5.6.2.8.5.3.e164.arpa. 3.1 NAPTR 1 1 "u" "E2U+sip" "!(^.*$)!sip:abc@bar.fi!i" .

have a look at http://enum.nic.at for a start, we actually have two registrars where you can register ENUM domains for telephone numbers

I am working to have some numbers made available for software developers so they can be provisioned through the Telekom Austria Portal

The idea of using ENUM at the server-side has a lot of problems

Example: you get this from DNS

1) NAPTR 10 10 "u" "sip+E2U" "!^.*$!sip:blabla@example.com!" . 2) NAPTR 10 20 "u" "sip+E2U" "!^.*$!sip:blabla2@otherexample.com!" . 3) NAPTR 10 10 "u" "tel+E2U" "!^.*$!iax:0900@expensivenumber.sex!" .

What to do ??

First try 1) or 3) ??? What happens if this failes ?? (not reachable, busy ??) Is the user willing to pay the costs for 3) ?? Maybe the user wants to dial the REAL number (remember ENUM is a additional information for the real world phone number). How will you find this out ???

My conclusion is that ENUM is ALLWAYS a funktionality of the client and NEVER of the server because of the need for the user to decide what he realy wants to do. Any automatic resolution will fail.

Maybe there is a need for a kind of communication between Server and Client (inside SIP ??) to solve these kind of problems. Any ideas how so solve this problem ???

Hi Mat,

Enum is basically a ITEF standard for mapping communications services

based

on a standard telephone numbers... the client converts a phone number

into a

dns entry then looks up records based on this conversion process

(documented

in the standard)...

There are a number of standards docs at the IETF web site describing the actual standard.

It seems like every problem is answered by "it's in the CVS version" but we're not supposed to use the CVS version because it's not stable.

When is the next stable release scheduled?

The new release is scheduled to be out as soon as we complete internal introductory tests and the user community tests the server too.

Again: combination of "new features", "for free", and "instantly" wishes is easy to understand but hardly achievable. You will need to give up on one of them, guess which is my favorite candidate.

ps -- feel free to use CVS, that's why it is on the Internet for you. I just want to make sure that you don't expect unrealistic safety from a car you pulled out of assembly line before it entered the air-bag station.
