Hello, I have a problem with hatching during a phone call on my sites in SDWAN. The MTU size has been changed several times but this does not solve the problem. I tried the ping www.meraki. com -l 1472 -f and adjusted the values but nothing worked. What value to put to be sure not to be hatched anymore?
On my sites deploying in SDWAN, the phone calls begin to hatch (they hear hatching) while we hear them well. Only call reception behind the SDWAN is impacted, not reception
Would you be able to share the MOS and packet lost status on the VPN? From my observation, 2% packet loss causes the MOS to drop around 3 and the VOIP start to be impacted.
Security & SD-WAN / VPN Status / Select your main tunnel on the green bar /
Another thing, do you have some SD-WAN policies configured to prefer a specific WAN interface?
(ex. prefer WAN2 for SIP)
Lastly, du you use traffic shaping rules for SIP traffic?
Yeah, you may want to investigate the Internet access. MOS bellow 3.6 would be difficult for VoIP.
We have over 75 sites with 2 Internet access each and the MOS average a steady 4.1.
do you have specific technical requirements, which you think are important on the internet subscriptions to subscribe to avoid this type of inconvenience!
Thank you in advance for your answer.
Sorry I don't except to avoid DSL type of access and 2% packet lost
But here are some good reading
