It would probably work if voice and data are on the same vlan. Have done it before with different phone types in shows and short term testing environments.


It is not supported and not recommended for production environments.

Hi Bill,


You will need to remember two things if you daisy-chain IP Phones together. The second phone will need to be powered by a Power Cube and this setting needs to be changed;


Forwarding Delay


Indicates whether the internal switch begins forwarding packets between the PC port and switch (SW) port on your phone when your the PC port becomes active.


Displays Yes or No.


When set to No, the internal switch begins forwarding packets immediately. When set to Yes, the internal switch waits 8 seconds before forwarding packets between the PC Port and the SW Port.


Set the Forwarding Delay to Yes if you connect both ports to switches for redundant uplinks or daisy chain phones together.


Cannot configure locally. Use Cisco CallManager to modify.


From this doc;

Hope this helps!

Rob
