Authentication Registration Failure

[jlee@cedarpointcom.com]

1. Brekeke Product Name and version:
2.1.6.6

2. Java version:
Version 6 Update 5

3. OS type and the version:
Windows XP

4. UA (phone), gateway or other hardware/software involved:
Grandstream BT100

5. Select your network pattern from http://www.brekeke-sip.com/bbs/network/ ... terns.html :
Pattern 1

6. Your problem:
I can not register the Grandstream BT100 to Brekeke PBX.
I have configured [SIP] Authentication [REGISTER]=on and [INVITE]=on.
I have verified the userid and password were set correctly on both Phone device and Brekeke Server.
However I keep getting 403 error with the second Register with credentials

Is there anyother configuration that need to be changed?

I donot have that problem. Make sure you set the userID and Password at Brekeke SIP > User Authentication, Not Brekeke PBX >users
