Hi there,

 

For a project, I have to build a VoIP network with this hardware :

 

3CX server on site

9 Yealink T41S IP phone

24 ports switch T1600G-28PS (TL-SG2424P)

Router TL-ER6020

Dsl provider router with TL-ER6020 configured in DMZ (VoIP dedicated connection)

 

There is nothing else on this network (PC, printer, ...), he's used only for VoIP.

 

My question : 

 

Does I have to configure something on the router or switch to avoid quality issues ?

 

Best regards,

If your network also has the other devices that may affect the VOIP traffic, you can set up voice VLAN to provide the high priority for VOIP traffic. You also can set bandwidth control to limit the bandwidth of other devices, then ensure the enough bandwidth for VOIP traffic.

If your network only has IP Phone, you don't need to configure the above settings.

@Andone Thank you !

So, I will leave the router & switch in out of the box configuration.
