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.

Hello,
I am trying to develop a simple but fast application/daemon to take SIP
invites, convert them into ENUM queries, send those queries to an ENUM
server (likely residing on the same hardware as the daemon), get back an
ENUM response and convert that to a SIP 302 (or other 300 level)
redirect response.
Before developing this type of daemon, I just want to make sure about
the expected daemon related to performance. If anyone has already done
this type of work, please give some comments regarding the following
performance issues, whether the following challenges are possible or not
in real scenario.
1. Daemon responds to an ENUM query in 0.7 milliseconds and answer
16,000 queries per second.
2. Daemon should add less than 1 millisecond to that roundtrip so a
SIP invite should get a 300 redirect within 1.7 millisecond.
I would appreciate if anyone can help me with relevant information. If
the above challenges are not possible in real scenario, then appreciate
for any near numeric figure which are possible to maintain in daemon.
Thanks
Nahid
