One way audio on SRTP calls after ~35 minutes
Added by Enzo Zazzaro about 5 years ago
Hello,
after about 35 minutes the audio is no longer recursive only audio output but nothing input. I speak of 10 operator CALLCENTER so in production I think it is a problem of KERNEL RTPENGINE on a forum they had the same problem and they solved with a patch on the rtp kernel
https://github.com/sipwise/rtpengine/issues/917
if you can please give me some advice on how to modify the rtp kernel. The system is fully functional but with this problem we are unable to work.

it does not work after 3 - 4 calls, it is no longer heard.
kamailio and astersisk work and have no errors I think it's a "keep alive" problem on kamailio that I don't see in the kamailio.cfg file is someone testing it? Are you experiencing the same problem? both outgoing and incoming

Sounds like some NAT/firewall issues. Does your server have a public IP or is it behind a firewall?
The following ports need to be opened(or forwarded to your server):
TCP: 80, 443, 4443
UDP: 5060, 5066, 10k to 65535.

firewall is open and server in CONTABO VPS
everything is working but it happens that every now and then the xlite call ends and you have to log back to resume the call.
kamailio:
tls: v1.2 +
certified letencript

Hi,
Which of the two guides below you've used to enable softphone registration?
a. https://goautodial.org/projects/goautodialce/wiki/HOWTO_Enable_Softphones
b. https://goautodial.org/projects/goautodialce/wiki/HOWTO_Enable_Softphones_Registration_per_User
Are you experiencing same issue even webrtc is enabled? did you install any card or 3rd party up?
Thanks

Hi,
If one agent only experiencing the issue try to check the following:
1. Agent workstation
*You might also need to check the agents workstations to see if they're not overloaded. Meaning they're just running the necessary applications for dialing (Chrome, notepad, or application required for dialing). Re-schedule system update like windows update and antivirus update.
2. Workstation Internet Connection
*Make sure workstation is using wired connection or connected using LAN cable
3. Bandwidth Consumption
*Might be eating all your connections. Make sure your internet connectivity is just being used for dialing purposes. Browsing social media sites like Facebook, Google+ and Youtube and others will eat up all your bandwidth.
4. Latency
*Most of the time it's the stability of the internet connection (latency issues). A stable network is more important when it comes to VoIP traffic and data. Latency has the reputation of being the enemy of VoIP and data. Average latency should be less than 200ms
For Troubleshooting:
Try to switch that agent to softphone registration just simply follow the steps posted here https://goautodial.org/projects/goautodialce/wiki/HOWTO_Enable_Softphones_Registration_per_User
Thanks

Had same issue. First call is always problem free and smooth.
One way audio starts after random time.
Later client switched to 3cx.

Hi,
You reply:

Same issue on one agent? Are all your agents are in same network or office?
Try also to switch the said agent to softphone.
