Odd Behavior on Accepting Registrations

[l.qian]

1. Brekeke Product Name and version:2.3.8.2

2. Java version:JRE 6 Update 16

3. OS type and the version: Window 2003 Server R2 Std

4. UA (phone), gateway or other hardware/software involved:Aastra 480i/Linksys SPA922

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/networkpatterns.html :Pattern 4

6. Your problem:Registration fails on the 1st or 2nd try with Not authorized message, then it responds with OK on 2nd or 3rd try. Shown in Wireshark capture. Sometimes people have to reboot the phone to get a successful registration when last registration expires.

[hope]

try with set shorter registration expiration time at client sides, like 2 - 3 min
