Have you done a port-mirror already and check the traffic from/to the phone? If you compare that between a working and non-working switch port, it may become clear what the difference is and from there how to resolve it.
If you have urgent issues, always contact your Aruba partner, distributor, or Aruba TAC Support. Check

In case your problem is solved, please invest the time to post a follow-up with the information on how you solved it. Others can benefit from that.

Yes Spanning-Tree ist enabled on the Switch.
We tried allready changing the port from admin-network to admin-edge, no change.

Could it be that you have spanning tree enabled on that access port, and may be keeping the port blocked for 30 seconds resulting in the phone timing out?

So i tested the new firmware 10.12.xxxx but no change.
What i noticed now - when i change the lldp timer to 60 seconds on the phone (default 30) it works.
So seems the switch takes somewhere to much time.

Hi all,
was involved into Troubleshooting and I suggested to Update Firmware to 10.11.x or 10.12.x to see if there is a difference.
Additionally the Packet Capture is suggested also as Herman mentioned.
We made a setup in parallel with HP Voice Phones 4120 with 6100 on 10.11.1021 & 10.12.0006 and it worked as expected. Captures are available for comparision.

Yes LLDP and LLDP-Med ist enabled - i see the Phone with lldp neighbor Info.
We use the Phones on many other HPE Aruba Switchs (2930, 2540, 5400).
UPDATE:
When i restart the Phone, it gets for some seconds (30s) the wrong VLAN-ID
-> Neighbor Med Policy VLAN ID : 1
After the 30s the phone then shows
-> Neighbor Med Policy VLAN ID : 2
But thats to late, because the phone got allready an ip-adress from vlan 1
So seems some sort of timing problem?

Have you enabled LLDP and LLDP-MED?
Does you phone support LLDP-MED to get the voice VLAN?
