VLAN considerations for CUVA


I got a broken connection when trying to use CUVA with IP phone 7911, but evrything is working fine using a IP communicator.

Is it necessary to have the PC and the IP phone in the same VLAN or just have connectivity between the 2 VLAN (via a router or a layer 3 switch )?

As the webcam worked fine with IP communicator , could we consider that this is a supported Webcam or this could be also the origin of the broken connection?


- Video capabilities is enabled on the IP phone ( the video icon is displayed on the bottom of the IP phone screen by the right side )

- pc firewall ois disabled on the machine

many thanks.

Re: VLAN considerations for CUVA


Usually IP phones and PCs will work on different VLANs, you just need to make sure that there are no Firewalls or Access Lists blocking communication from one vlan to the other. If this were the case, the camera and video software will not be able to communicate with

the local IP phone. So sounds like a routing (L3/inter vlan routing) issue as it works fine with the IPC.

Tou can get a sniffer trace and see when you use IPC with CUVA which port you use and what happens when you use CUVA and the 7911. Probably there is something blocking the UDP port needed.

Also when using software like Symantec Endpoint Protection on the PC, even when it's disabled CUVA doesn't see the IP phone, so you need to uninstall it.

To discard any issue with the phone's firmware, make sure you are running the latest one and the latest CUVA version too.

Re: VLAN considerations for CUVA


check if cuva could "see" the phone equipment (7911), if not appears the "wire" between the camera and phone, means you had a problem with the communication inner phone and software, check in the phone in the menu if the vlan of data has enabled on the ethernet to the pc, second, check if the vlan of audio reach the ephone.

check if the ccme or cme, see the ephone with video enabled, and enable video on the cme or ccme for the ephone.

check this first, i'm keep this post on eye.
