Hi,
config :
VERSION: 2.6-372a
BUILD: 120713-2123
from goautodial 2.1 64bits :
Server :
Intel(R) Xeon(R) CPU W3530 @ 2.80GHz
24GB

asterisk 1.4.39.1-vici
dahdi-tools 2.5.0.1
no timing source
WAN : 100mpbs
SIP Provider

Manual calling with softphone : sound is clear
Calling via Agent interface (both outbound and inbound) : bad quality , choppy sound.

i have looked at the forums and tried some changes in asterisk :
[options]
transcode_via_sln = yes
internal_timing = yes
transmit_silence = no
highpriority = yes

but still no solution.

any idea or solution?

Thanks

Bad sound can be related to a few different things.

Do you have enough bandwidth to cope with the strain of the ViciDial on your server?

Do you have any Firewalls? Or proxys that could be blocking the traffic?

If so make an exception for the dialer and re test.

the server is on 10mbps internet access
i have a voip compression appliance (i have tested it without , no changes) and all traffic goes through it.

No firewall, and proxy , everything is open (for the test )

i have tested with G.729 , GSM : bad quality
G.711 : good
same with and without recordings enabled

calling directly (manually) via the server or directly to the VOIP provider : the problem does not appear
as i understand (reading the forums ) is that vicidial uses conference and transcoding process add load to the server
i cannot use G.711 due to management restrictions , they want to use a compressed codec.

It could mean that your settings are incorrect. (Dial plan and/or carrier settings)
OR
There is a proxy or Firewall preventing all the traffic from reaching its destination.

From a networking point of view, are you using cat 5 cables? or cat 6?

Have you got any form of network monitoring or managing (E.g wireshark)
If you get wireshark for example you are able to monitor the packets of information that go all around your network and pass through your router.
From this you will be able to see where you packets are going. Because the packets never disappear - theyre floating about in some memory somewhere.

The problem is that your system is VOIP and thus needs ultimate connection and loss of connection ANYWHERE can cause you to lose a packet or two of data every now and again and this could be the problem?

And when you say your internet speed is 10mbps ...

Is that 10 up and 10 down?
Or just up?

Calls fed to the agent interface are conference calls. Did you test a regular conference call? If that is also an issue I would look for timing problems.
