Question about Cisco 7940 IP Phone

My client has Cisco 7940 IP phones and wants assistance with feature programming

I'm a consultant who's been handling a client's infrastructure upgrades over the last couple of years and they have asked for my assistance with feature programming on their Cisco 7940 IP phones. They have dissolved their relationship with the firm that was handling the telecom administration and they are not able to provide any documentation detailing their environment. It's a small environment consisting of about 20 phones. Is there a way to determine how the environment is configured and where to gain "console access" for feature programming?

This phone can be access through a menu/ setting buttons.

I think the main problem is to determine the intergrated router or Call manager configuration
You can also connect on switch and type:show cpd neighbor This will show the physical port connections

  3. your phone has time -of-day restrictions that prevent you from using some features during certain hours of the day

Cisco IP Phone 7940 and 3com nbx as 3rd party SIP phones

Here are the instructions for configuring these units for 3cx

Since the 3cx softphone worked well, I don't see why you couldn't configure each as for 3cx and make them work as well.

'in call' volume cisco 7940

The handsets will eventually go bad. If it is every single handset that you have, the problem is with the system. But if the problem is only with a few of your phones, you might consider replacing the handsets. We at have replacement Cisco handsets for sale at only $25. Hope this helps you out :)

Cannot program Speed Dial

Try adding Cisco 7914 (time two) for additional (other) phone lines, or define caller group so phone call rings around.
