Could someone please help me understand what needs to be done transitioning from Cisco VOIP to Avaya? Specifically, Option 242 that needs to be configured on DHCP Voice Pool? The client claims that the phones are staying in Data Vlan (Vlan 1) and not going over to Voice Vlan (Vlan 900).
The setup is pretty straight forward. There is one building (3 closets total) and only 2 Vlans: Data and Voice.
Vlan 1 10.12.0.0/16 Data
Vlan 900 10.13.0.0/16 Voice
The Cisco 2921 Router is configured for Voice DHCP like this:
ip dhcp pool VOIP
network 10.13.0.0 255.255.0.0
option 150 ip 10.13.0.10
10.13.0.10 is the Call Manager IP.
I believe there is an Avaya server (controller) onsite that will be acting as DHCP for the new Avaya phones.
What needs to be done for the Avaya phones to obtain 10.13.x.x IP addresses and not 10.12.x.x ? I've read about Options 242 (or 176) that need to be configured but I'm not sure how to go about it. I haven't really worked with Avaya phones before.
What about LLDP? The switches are Cisco, 2960x. Switchport are configured to access vlan 1 and Voice vlan 900.
Any help would be appreciated!
