Avaya IP Phone with Cisco Switch

Hi I have installed the Avaya Voip system in Cisco LAN network, the Voice DHCP is running the Avaya Server and Daya Subnet is running in the Windows Server. PC is connected to Avaya Phone and Phone is Directly connected to Cisoc Switch..

The issue is PCs are getting IP address from the Data Dhcp ( Subnet ) and Phone is Getting IP from the Voice Subnet from Avaya Server without Issue, but the Ip phone MAC is not learning in the Cisco Switch I have configured

Swithport access VLAN 10 ( Data )

Swithport access Voice Vlan 20 ( Voice )

Hence I am not able to reach the voice VLAN ip from the Date , I have updated both VLAN subnet in my router dynamic routing. Kindly any one provide the help for this issue
