Hi,
During the calls my agents complain that they are getting echo. Here is my config :
1. Database + Vicidial
2. Asterisk (both Optron dual core 165 + 2gb ram)
with a ratio of 1.5 for 20 agents with a 1MB line. All client macines are running windows with Idefisk.
thanks

Hi,
what is the soft phone you using,iax or sip.iax softphones do have great feature of echo cancellation.You can try idefisk.In filter option you will get echo cancellation feature.

Sorry if the posting did not have more info:
1. We have a 2 srver setup (Both Opteron 165 with 2GB RAM and 160GB SATA)
2. 1Mbps Leased Line - Fractional E1
3. Agent machines use Idefisk / Mozilla Firefox. They have onboard sound cards (I know we have to look into this)
4. Total ofd 17 agents dialing at 1.3 using g.729
5. Load Average < 3 most of the time (I'm guessing since we have an Opteron with HyperTransport - we are ok with loadavg <=4)
6. memory utilization - less than 100%;
7. SIP trunk (g729) to dial out / IAX to the agent machines (gsm)
Our problem:
The agents hear echo in about 15-20% of the calls. loadavg less than 3.
we checked iax2 show netstats - there seems to be some jitter in the network - but nothing very serious.
Any help appreciated
thanks
