VLAN Issue - Cisco 2960/HP 2520G

So here is my issue. I have a NEC VOIP phone that uses VLAN 7 for communication and passes untagged traffic to the computer.
This Phone is plugged into a Brand New Cisco Catalyst 2960 that is behind a ProCurve Switch 2520. The Procurve is setup with VLAN on the Fiber Port going to the Cisco SFP Fiber Port 28. I need to enable VLAN 7 on all ports. This is what I have tried so far on all ports. What am I missing?

switchport access vlan 7
switchport trunk allowed vlan 1,7
switchport mode trunk

The way you configured it, you enabled VLAN 7 on port as tagged traffic, however VLAN 1 is untagged by default, I guess that should not be issue, but I don't know what NEC phone expect (maybe data traffic should also be tagged?).
Maybe you are looking in wrong direction is VLAN 7 enabled on trunk. What is your real issue?

Here is the current configuration. I made the changes that you suggested Lopo. These phones work fine on the HP but not on the cisco attached to the HP. Port 28 is my SFP Fiber coming from the HP. Port 22 is the phone. I can ping the gateway for the phone just fine. But the NEC InaSet 320C is setup to communicate on VLAN 7 and pass untagged to the PC.

You did not configure trunk to other switch. You have only access ports beside that one.
On interface that is connected to HP switch you should configure trunk the same way as that port to be able to comunicate with VLAN 7 devices on HP switch (also HP switch should have tagged interface on port on the other side for VLAN 7.
if you issue
#sh vlan
you will see that all ports are access ports in VLAN 1
# sh int trunk
Will list you only port gi1/0/22 as a trunk.

Yap, there is no trunk on interface to HP switch, you need to configure it.

And this port configuration may not work with your phone, maybe you will need to configure port like in the first post

interface GigabitEthernet1/0/22
switchport voice vlan 7
mls qos trust dscp
spanning-tree portfast

Maybe it will, but there is no guaranties. Configure trunk like you did in the first post on interfaces that conects this switch to HP switch. Also port on HP switch should be tagged for VLAN 7, and untagged VLAN 1.

Hi iTeam,

Kindly confirm if the above suggestions by the expert were implemented.
Below should be the layman exhibit of your network.

The following configuration worked great. I was originally confused because this was what I had done before except the portfast. BUT the portfast had made a quick discovery on the original issue. See, with portfast you CANNOT have more than one Router to Router port. Anything more than that will cause a loop and it kept crashing the HP switch. This had shown me that we had a loop on our fiber network which we had though were going to separate switches. We were wrong of course. Can't wait to start our fiber mapping. I quickly remedied and all was well again. Thank you for all your EE Team.

Thank you Lopo and PredRag. Lopo was right on the money in his post. Predrag, I appreciate your input as you had done the same thing I did a couple days ago. What I found out with enabling trunk though is it doesn't work so well with our configuration for some reason. The phones would still not work. Once I change all the switches to Cisco's, you solution is more viable. Thanks again guys.

Once I change all the switches to Cisco's, you solution is more viable.

No. There is no need for that. I thought that those phones will not work with current configuration (switchport voice), that was the only reason for that configuration. All phones should work with trunk configuration... (Cisco's implementation is not available on other vendors devices). Cisco actually has 4 configuration templates for IP phones, and your current implementation is preferred...
Since you have mix of HP and Cisco switches you should configure MSTP instead STP or RSTP (compatibility reasons).
