I dont think the avaya phone works without the trunk configuration on the port.

As per my experience trunking is not required for the new nortel phones but for avaya it is a must.

Yes i agree..

Old Avaya phones do not work without trunks but the newer phones do work without the trunk configuration.

Number of spanning-tree instances is a problem hence when it used to be defined as a trunk, it was a good prctice to allow only the data and the voice vlan across the port

Without the trunk configuration though, there can be no qos applied based on COS.
