7942G IP Telephone

[irenebernad]

How can be connected a headset and a buzzer and a beacon to a 7942G IP telephone? If it is possible.

[paolo bevilacqua]

Headset has a dedicated port, buzzer is not possible, you will need an analog port in SCCP mode to connect buzzers or other types of device.

Thanks for your explanation, but, is there no way to connect to this telephone any signalling device?

[paolo bevilacqua]

As mentioned above, there is no way.

Regarding to the 7942G IP telephone, is it necessary to have a Server in the network to manage these telephones? Or are they servers in themselves?

[paolo bevilacqua]

Yes must use a server, cisco CM, CME, or third-party.

Call Manager or Call Manager Express are the cisco products needed to make the telephones work.
