A call requires 0,1mb/s download and upload speed. Since your calls run through an internet connection along with all other traffic within your network, it’s impor- tant to have enough capacity for this. We highly recommend a fiber connection.
To ensure that there is enough bandwidth for the phone service, we recommend that you set the rules for Traffic Shaping in your firewall to prioritize traffic to and from Telavox. An alternative to this is to set the Quality of Service to prioritize tagged packets. We tag all packets with the following:
- For RTP (sound/media) Expedited Forwarding (EF) DSCP46 = TOS184/0XB8
- For SIP (signalling) Assured Forwarding (AF31) DSCP26 = TOS104/0X68.
Only hardware purchased from us including our softphone have these tags.
