AUTO-VOIP VLAN or manual, need help with initial config. two Networks in use as well
I will admit up front that I'm a bit new to VLAN and some of the terminology. I understand what they do, and basically how they work, but not things like LAG. My scenario is my ISP is handing me ...

Thanks DaneA,
I finally ended up calling support but I will read the two articles you noted as well.
Turns out the issue was fundamentally simple-- I simply needed to put the feed for the data network (1D) into the default VLAN, while putting the Voice router feed port into the Voice VLAN (2P) . Then I tested it with an Aastra phone, using the OUI-based Auto-VOIP method. The Aastra phone automatically chose VLAN2, and then grabbed a DHCP from the VoIP router.
In practice, it was a bit different. The phones in use were Cisco and they simply WOULD NOT grab an address from the VoIP Vlan. Another VoIP phone (a Polycom) worked fine!
The solution was to visit the Voice VLAN config page and enable LLDP for those ports and though LLDP, the switch was able to switch the VLAN to 2 BEFORE DHCP was requested, which meant they finally picked up the right address and started working correctly. Before that, All the Cisco phones would pick up the untagged default VLAN DHCP network, and then switch to the Voice VLAN, but using the data VLAN IP address. Friggin Cisco.
