asterisk users - Dec 2005 - SIP ENUM Daemon

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

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
