IP Default Gateway not included in DHCP broadcast for VoIP connection [CPT]

I am going to provide the show configs first:

Router0: https://pastebin.com/naNTZizs

Router1: https://pastebin.com/fbnEHkg5

Switch1(Multilayer): https://pastebin.com/BUhx8iwd

Switch0(Access): https://pastebin.com/6bXk7czN

Now here is my topology overview: https://imgur.com/a/GHnPd

So every device has an IP address. The data for the computers is being sent on VLAN 20 DATA. Separating it from the voice traffic which is VLAN 10 VOICE. For some reason my devices, on the right hand side of my network, are receiving IP configurations, but my IP phones aren't receiving IP Default Gateway information from the DHCP packet.

Need some help figuring this out, thank you :)
