Hello all, I'm a little bit struggling,

I need some help in configuring auto voip on sg3428.

So I have a Cisco router that has dhcp pool, one for the native vlan which is 1 and the second is for the ip phone. port 2 from the router is directly connected to the switch which has the ip phones (vlan 30), port 1 of the router is connected to a dlink switch and from the dlink to the tplink for the native vlan (vlan 1).

I have created a vlan 30 and activate auto voip globally, on the interfaces that connect the phone and pcs ( switchport general allowed vlan 1 untagged, switchport general allowed vlan 30 tagged) activate lldp and lldp-med globally, set the port between my switch and the router on trunk with switchport general allowed vlan 1,30 tagged.

When i plug the yealink phone on the switch I get the 10.10.30.x and 10.10.30.x on the pc also, but the internet is down on the pc, means that the router just distrubuted the ip phone vlan.

I have searched for similar scenarios with yealink ip phones and tplink switchs but I didn't find anything. I founded a guide for the auto voip on tplink website but the same thing. If u can help I will be appreciated.
