 Posted: Wed Aug 20, 2014 3:53 pm Post subject: [asterisk-users] Dispatching calls question |
 |
|
I have a question about dispatching calls...
If I try to dispatch a call on line 1 using the AMI
and I check in my table to see if line 1 is available and it is....
So I have done my checking now I dispatch my call
and at that same time a call comes in on line 1 and now its no longer available
for me to make a call, I connect on AMI and my call fails....
How do I prevent this from happening? Sure I can start at 23 instead of 1 and work down
instead of up but eventually the same thing may happen.
I'm using Asterisk 11.11 if that matters.
Thanks,
Jerry |

If you're using something like MySQL, use 'get_lock/release_lock.'
If you're using some other database, see what locking features you have
available.

Asterisk 1.8 and later have lock functions available in the dialplan. This might be better if you have a single Asterisk server.
pbx*CLI> core show functions like LOCK
Matching Custom Functions:
--------------------------------------------------------------------------------
LOCK LOCK(lockname) Attempt to obtain a named mutex.
TRYLOCK TRYLOCK(lockname) Attempt to obtain a named mutex.
UNLOCK UNLOCK(lockname) Unlocks a named mutex.
3 matching custom functions installed.
