Hello Experts!

I'm taking on a new to me network and have found some voice quality issues. The phones are hosted through  Ring Central and we use Panasonic KX-TGP-500 / 550 VoIP phones. We have 11 phone lines and approx. 25 workstations and 10 servers. We use Charter Business 50MB download / 10 MB upload and have a fortigate 40c firewall.

We're having voice quality issues which are random and hard to duplicate, but assuredly happen when on a conference call with a client! We've had two open tickets with RingCentral for months and have combed through the firewall to no avail.

We do use Citrix Receiver to connect to a clients XenApp environment.

I have disabled SIP Helper ( Layer 7 ) on the firewall
I have the requested ports open for UDP
I have created a Voice VLAN on the dell switches and put the three ports of our phone bases in the VLAN -

Here are some questions - Do I enable the Voice VLAN on all ports? If not, do I enable Voice VLAN on the ports that join switch to switch and switch to firewall?

I really want to see quality improve and we are not maxing out our bandwidth up or down so I am stumped.

I am new to VoIP and switch configuration (my background is primarily application support and desktop support) so forgive me in advance if I ask for clarification or a greater detailed answer. I really want to understand the why as much as the how.

THANK YOU!!!!

Let me try to put in my 2 cents:

No need to enable voice on all ports if you're not going to use it. It might be handy if you want to be able to just plug in a phone at any given port.

You'll indeed need to 'stretch' the voice VLAN to the edge of your network, so from switch to switch and from there to the firewall.

Try to apply QOS whever possible in your network.  Did you already do that? (nice little article: http://en.community.dell.com/techcenter/networking/w/wiki/configuring-dell-powerconnect-55xx-series-switch-voice-vlan.aspx)?

Also try to do that on the firewall:
