VOIP devices are not receiving IP

Hello all,

We are using Siemens 15 HFA phones directly connected to the VOSS switches. Authentication is done using XIQ.
When EAPOL status auto is disabled, a MAC address is present on the port, and the device responds to pings.
When eapol is enabled, there is no more MAC and the device is not responding to ping, even if the authentication is working :

show eapol session-stats interface gigabitEthernet 1/36

On the XIQ

The port is configured as a trunk and auto-sense is disabled on the ports. VOIP VLAN is 80.

interface GigabitEthernet 1/36
default-vlan-id 0
qos 802.1p-override enable
access-diffserv enable
flex-uni enable
no shutdown
slpp-guard enable
no spanning-tree mstp force-port-state enable
eapol radius-dynamic-server enable
eapol status auto
eapol multihost radius-non-eap-enable
eapol re-authentication enable

Do you have any suggestion about what i should change to make it work?

Thanks and regards,
Alex

The issue is resolved. The problem was on the phone side, some hard-coded configurations on it.
