Hello - I have a flat network (one subnet) that we are adding a VOIP system into. We are installing a 4510 Switch in the core and each of the 4 wiring closets will have one 3560-POE 48 port switch with fiber back to the core. I think I understand the use of a separate VLAN for the voice network but I'm having a hard time getting the setup of the separate subnet for the voice vlan and getting that subnet to talk to the other VLAN for configuration from the TFTP server (primary call manager). The 4510 has a primary and secondary supervisor engine. The Primary and secondary call managers are on the data subnet. Can someone point me in the right direction for getting the VLANs and Routing information correct? The ports on the switches will need to run multiple vlans since the computers on the network will hook into the new phones. The new IP phones are mostly 7941s with a few 7911s and 7970s.
You have to have Gateway in your dhcp conf to get it worked.
