That's exactly what it is doing unless I am misunderstanding. You didn't 
answer my question last time - is Asterisk actually "crashing?"



It is causing the CPU usage to spike dramatically.


If you are able to provide reproducing steps, feel free to open an 
issue¹ and someone will take a look at it. If you don't want to do that 
for whatever reason, you can install a proxy (like Kamailio) in front of 
your Asterisk server which can weed out malformed SIP packets like the 
example one you provided.


Kind regards,
Sean

Sure it can, but:

sip:Radefeld Dental@8.38.43.67

Is not a valid SIP URI (it can't contain a space). Is Asterisk actually 
"crashing" or are you just seeing this error in your logs?


Kind regards,
Sean

Did you try to remove the space or replace it (eg underscore) in SIP id 
likemailto:Dental@8.38.43.67>> ?

Can this be fixed?
