Summary:                    SIP/2.0 400 SIP Parser Error : Missing '@', line 3,
column 26
Description: 
Linksys WIP330 Phones cause Sip Parse Errors and Crash Asterisk Completely,
It crashes most when you get a new incoming call then it will show No
Caller ID you will have silence on both ends of the line.
Then you have to restart asterisk, sometimes it will lock up asterisk
where you can't even do a stop now and you have to kill the process. When
this happens is throws errors like this.
SIP/2.0 400 SIP Parser Error : Missing '@', line 3, column 26

If you turn off the Wip330 phone the systems work great. So I know it is
directly related to how theses register with SIP.

Occurring on Multiple Server Running Different Versions of Asterisk.
