VoIP Phone has a connection, but phone does not work
Hi All, I'm upgrading to new switches and trying to get voip and data vlans working so users can plug computers into backs of phones. Working with a GS752TPv2. Data is vlan 1 (default). Voi...
For anyone who stumbles on this, I found my mistake.
The phone has only 1 IP address. When I tried to split off VLAN 20 to go out port 47, I wouldn't work because port 47 connected to the gateway at a different subnet than the phone was on (our current setup has phones and computers on completely separate networks). I wanted to let people plug data in through the phones so it had to be on the data LAN.
Once I changed my firewall rules to allow the plethora of ports used by my phone company to talk to my data lan as well as my phone lan, it worked!
I now have auto-voip set up. I'm still baffled about how this works with Phone VLAN, or if it even does. I think the auto-voip sees phone traffic and priorizes it appropriately. Not sure how to test I have it set up right other than plug a bunch of phones in and get them all on a conference call while transfering data through the switch. I did this with two deskphones, a polycom style speaker phone, and my cell phone dialed in, and it sounded fine.
Fingers crossed for my deployment next month.
Thanks,

Hi John,
I don't want data (vlan 1) going out port 47 at all. Only phone traffic should use that. Data goes out a LAG on SFP 51-52. I tried vlan 20 tagged on port 47 as well but no dice.
Is that not the way to do that?
Thanks,
Jeff
