[asterisk-users] Asterisk using 100% of CPU

[Chris Elliott]

When I initiate a call from the console (Console/dsp) to a local SIP 
extension, asterisk uses up 100% of the CPU until the extension 
answers.  It happens when using .call files or the manager API.  My 
examples are for the manager API, but .call files perform the same way.  
Here is the 100% CPU example:

Action: Originate
Channel: Console/dsp
Context: internal
Extension: 20
Priority: 1

If I reverse the situation it gets a little better.  Asterisk doesn't 
use 100% of the CPU, but until SIP/exten-20 answers, the manager 
interface doesn't respond.  So I can't hangup the line using the manager 
API if SIP/exten-20 doesn't answer.  SIP/exten-20 is a SPA3102 FXS.  
Here is that example:

Action: Originate
Channel: SIP/exten-20
Context: internal
Extension: 0
Priority: 1


If I initiate a call from Console/dsp to the FXO port of a SPA3102, that 
works fine.  Example:

Action: Originate
Channel: Console/dsp
Context: internal
Extension: 98005551212
Priority: 1

I am using asterisk is version 1.2.24.  Basically I would like to be 
able to use the manager API to externally initiate calls from the 
console and hang them up.  Any ideas here?

Here are the relevant parts of extensions.conf:

[general]
static=yes
writeprotect=no
autofallthrough=yes
clearglobalvars=no
priorityjumping=no

[globals]
CONSOLE=Console/dsp
