Need help on LRERR 4 issue

[joeymagsino]

Hi,
I have a problem on my vicidial installation. The first 30 minutes went fine for auto-dialing, meaning all outgoing calls go through for all leads and the call gets forwarded to agent. But after 30 minutes, i've noticed that all of my agents is not receiving anymore calls or the call is not forwarded to them.

After tracing the log i saw the in the agiout log this one on those moments the call is not forwarded to agent.

2013-04-05 11:38:19|agi-VDAD_ALL_outbound.agi|+++++ VDAD START LOCAL CHANNEL: EXITING- 4
2013-04-05 11:38:19|agi-VDAD_ALL_outbound.agi|LLLLLLLLL LOCAL CHANNEL PRIORITY 4 LOGGING: (this is usually caused by carrier issues) LRERR 4
2013-04-05 11:38:19|agi-VDAD_ALL_outbound.agi||UPDATE vicidial_list set status='LRERR' where lead_id='10623' and status NOT IN('CBHOLD','CALLBK','CBHOLD');|

Can anyone give some explanation on why this is happening?


My setup is :

Agent<->Predictive Dialer(vicidial) <-> Asterisk 1.6.x <->router<->voip provider

Predictive dialer ip: 192.168.1.97
Asterisk Dialer IP: 192.168.1.99

The setup of this 2 are here in the images :

Also please note that the asterisk server is already the existing dialer and we dont want mess up the existing setting. All of the ports 5060 udp and tc, AND the udp 10000-20000 is also forwarded to 192.168.1.99 Asterisk server so we just decided to make use of it.

Here is my vicidial version

Vicibox 3.1.5 from .iso | Vicidial 2.6-375a Build 120831-1523 | Asterisk 1.4.38-vici | Single Server | No Digium/Sangoma Hardware | No Extra Software After Installation |Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz

*note my server is just a normal pc for testing purposes.


Again, can you give me an idea on the cause of this error ?

That error means that there is no audio on the channel and vicidial can't send the call on to an agent if there is no audio. Audio on the channel is necessary for the Local/ channel to resolve to its proper pointer, and without that all sorts of things go wrong.

This could be a carrier issue, a network issue or just a random error with a SIP proxy somewhere in the path of your call.

to test, reboot your router and your vicidial server to see if this resolves the issue. it may help you find your problem.

Thanks all for your quick reply. I'll be tracing then where in the path of my network thisno audio problem happens.

Hi,
We've managed to resolved this issue last time by simply allowing the rtp traffic on the firewall. Our system administrator finds out that the firewall is blocking some of the traffic that goes through to and from Vicidial predictive dialer. Thanks again for all your help.
