Auto Dial stop placing calls

[pedrograna]

Hi

Im using VERSION: 2.0.4-121 and asterisk 1.4.19

The fact is that today the autodialing campaigns stop working not placing calls.

The most off the campaigns use dial method RATIO.
This is what AST_VDauto_dial.pl says.

Theres agents logged in but the scripts says LIVE AGENTS 0
Is this normal?

No errors at asterisk levels sip trunks working ok.

Thanks in advance

I miss something:

The select from vicidial_live_agents shows agents in READY status.

Did you reently change IP addresses by chance?

Its working, magically after rebooting the server and wait for aprox. 40 minutes. The live agents appear again, and autodial starts placing calls.

I have the same problem. In ratio method agents works fine 30minutes and after that dialer stop placing calls?
I have also the same problem in any adapt method. asterisk cli did not show any errors.
Manual dial works fine.
What could be the problem?
Maybe network device make a problem or internet provider?
Does anyone had the same problem, any suggestion or advice what to check or...?
