Red5phone Error ==>Reg. Failure = 404 Not found

I ran into this error: Reg. Failure = 404 Not found immediately following the Connection Success when trying to do the LOGIN in red5phone.

I am running a server that hosts the following:

  1. Asterisk 1.2.24 (Trixbox 2.6)
  2. OpenFire 3.5.2
  3. Re5 Plugin
  4. SIP phone Plugin

I can use Spark Client to do the Dial, Hold, Disconnect but was unable to get thru this error in red5 phone.

I do very much appreciate any help I can get, and many thanks in advance.

The answer is always in the log files. Most cases with Asterisk are the SIP realm name. Check sip.conf in Asterisk.
