Help VoIP bandwith calculation over an SD-WAN Link.
We were discussing today about how much bandwidth we need to allocate per call or per connection to incoming and outgoing voice. SD-WAN has for some reason degradated the quality of the normal voice operation compared against the MPLS or Metro-Ethernet.
I am trying to figure it out: 1. if the Legacy VoIP Standard also applies to the SD-WAN and how much percentage needs to be assigned to voice.
300 ms latency
30 ms jitter
1% packet drop.
30% bandwidth allocated to priority for voice
is all that still valid for SD-WAN?
2. Also, please help me to answer this question.
How much bandwidth per call do I need to allocate from my links if the codec is G711 or G729.
I know we need to calculate payload, L2, L3/UDP overhead... and that's it? no GRE or IPSEC or Site to Site VPN? for the calculation?
