Problem with switch SG300-28P Poe and Avaya 1408 telephone

[yesenia-m]

Hi Team

We have a model SG300-28P Switch 28-Port Gigabit PoE Managed Switch, in every port we are allowing the voice VLAN and data VLAN (trunk), happens to be off this type of phone, we reconnect the cable and port the switch is dropped, so that the voice vlan phone is lost and no longer work.

Thanks for your comments.

Hi Yesenia, did you contact Avaya support? Did you configure the phone for a voice and data vlan?

I'm trying to dig through the Avaya website and looking at the fact sheet and user guide it has no mention of VLAN.

Is the switch supported for the usage of Avaya Aura Communication Manager call processing system?

We solve the problem by setting the switch port in general mode

Thank you
