Voice VLAN between 6248 and 5548

Hello,

I have set up voice VLAN (20) on our 6248 with a network of 192.168.20.0/24.  I have that network along with our administration VLAN (110) pushed to the 5548 (tagged for 20 and untagged for 110).  I have two Meraki switches that also have VLAN 20 tagged along with 110 tagged (1064 VLAN untagged) and it works perfect with our digium phones in that the phones get VLAN 20 and the machines connected get VLAN 110. However, with the dell 5548, I can't get it to work.  Here are some screen shots of my configuration:

Dell 6248 (Port 37 to 5548)

5548 (port 1 to 6248 and port 45 to digium phone)

This is my current config, but I've tried a few different scenarios to get this to work with no luck.  I've added the OUI of the phones as well.

I've also tried the steps below with no luck:

Console(config)# vlan database
Console(config-vlan)# vlan 20
Console(config-vlan)# exit
Console(config)# VOIP vlan id 20



Console(config)# interface gigabitethernet 1/0/45
Console(config-if)# switchport mode trunk
Console(config-if)# switchport trunk allowed vlan remove 20
Console(config-if)# voice vlan enable

Any help is greatly appreciated, thanks!
