On the router, create 2 sub

On the router, create 2 sub-interfaces one for voice and one date

example:

interface FastEthernet1

interface FastEthernet1.10

ip address 199.11.28.19 255.255.255.248

encapsulation dot1q 10

 

interface FastEthernet1.20

 ip address 192.168.1.1 255.255.255.0

encapsulation dot1q 20

Also trunk the switch interface that connect to the router with vlan 10 and 20

HelloWhen using secondary

Hello

When using secondary addressing DHCP will chose the primary ip address for dhcp and offer address from that primary dhcp pool, There is an option you can use call smart-relay which will poll for an address on from the secondary pool if the primary pool is exhausted.(we actually use this feature on one our trusts cores)

however In your case your have defined a static so DHCP doesn't require a dhcp pool for this, But i am thinking this router will need an active interface on this subnetwork for this static addressing to be allocated  like the suggestion by Resa
