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.

I have also tried to see if it does it on the follow versions of asterisk and it does the same thing.

asterisk-1.4.17
asterisk-1.4.18
asterisk-1.4.18.1
asterisk-1.4.19.1
asterisk-1.4.19.2
asterisk-1.4.21-rc1

Does it actually crash?  Based on your description, it sounds like it is locking up.

Build with DEBUG_THREADS enabled, and when it locks up, grab the output of "core show locks".

# asterisk -rx "core show locks" > lock.txt

and upload that file here.

Note this: Unknown SIP command '2070SIP/2.0' from '97.101.232.29

Over UDP, that's weird.

We need to see the full dialog, what the Linksys sends too (see the bug guidelines). Obiously the packet coming in has some issues.

I tried sending the message quoted in the bug report into chan_sip and I don't get an error message when parsing it.  Also, based on your error messages, it seems like what actually go received isn't quite what was sent.  A real packet capture using wireshark or tcpdump would be even more useful.

Closing.  There hasn't been any response from the reporter since this was opened.  We'd like to get to the bottom of this, but without the requested logs that's going to be nearly impossible.

Please reopen this issue once you are able to provide what is needed.
