Re: CISCO IP PHONE 3905 is not working with HP A5120E POE

Change the config for the port-type from hybrid to trunk. Get rid of VLAN1 from the trunk.

 

When you are going with a multi-vendor setup, you need to eliminate anything that is vendor-specific.

The Cisco phones are either "trunk" or "access" (ie, 802.1q enabled, or not), whereas "hybrid" doesn't have an equivalent on the phones.

 

Next, how does the phone get its config?

Cisco phones with Cisco switches find out the "Voice" VLAN using CDP, but with a non-cisco switch, you might be using DHCP to assign the VLAN, or to assign a config server with uploads the phone's config file.
