Help setup voice vlan on c9300l-24p for dlink ip phone

[Blackha8732]

i have configured two VLANs on my switch ports. data and voice VLAN.

but when i connect a dlink ip phone and configure it to access the voice vlan, the ip phone doesn't communicate with the voice vlan on the switch. What else do i need to do?

interface range GigabitEthernet1/0/1 - 16
switchport access vlan 20
switchport mode access
switchport voice vlan 66
spanning-tree portfast

The information you provided only access-port config on the switch.

we do not have below information  :

1. how is your network connected to reach voice VLAN IP ?

2. where is your DHCP and what IP address range voice vlan ?

3. from what source you are not able to reach voice VLAN ?

2. The ip phone have static Ip addresses and re connected on ports 1/0/1 to 1/0/10 of the switch.

3. when i disable vlan seeting on the phone, the phone works, but when i enable vlan on the phone, it doenst register to the network.

On the network, i am having a dlink pbax with ip 192.168.20.253 connect on port 1/0/18 of the switch, and dlink ip phones connected to port 1/0/1 to 1/0/16 of the switch with static ip addresses. see the below configuration.

1. the range of my ip phone addresses will be start 192.168.20.10 to 192.168.20.150

2. the dlink pbax with ip 192.168.20.253 is connected on th switch pot 18.

3. when i disable vlan on the switch the phone registers well on the network and i can even access it via web. but when i turn set it to access voice vlan, the ip hone doesnt register to the network.

Please advice what to add on my switch configuration below, to help the phone access voice vlan 66 and pc access vlan 20 through the phone pc port.
