[Asterisk-Users] SIP ENUM Daemon

[Klaus Darilion]

Hi Nahid!

Why do you want to do this? What about the ENUM resolvers inside 
asterisk? There is the old EnumLookup application, and the new the 
ENUMLOOKUP function (with plenty of features). Have you tried them?

If you do not want to use asterisk's internal ENUM resolvers, you could 
also use (open)ser just for you purpose. It makes the ENUM lookup and 
replies with 302.

regards
klaus
