Unable to connect jabra t5330 to a cisco ip phone 7941G headset jack

See setup of your headset and check mic. Its looking mic problem.

Go into your sound settings, and enable the +20 gain settings on your mic setting.
It's a weird thing, mics not detecting what they're supposed to do, but it happens.
Unless you haven't installed the updated drivers for the unit? Try going to the website, and d/load the updated software for it, make sure it's for your hardware, and install it. Winblows can be outdated sometimes.
Hope that helped, in one way or another.

Complete these steps:

1. Unplug the power cable from the phone, and then plug in the cable again.
2. Immediately press and hold # and while the Headset, Mute, and Speaker buttons begin to flash in sequence, release #. ...
3. Press 123456789*0# within 60 seconds after the Headset, Mute, and Speaker buttons begin to flash.

either the switch is partially shorted or the pin on your headet has a shorted wire in it somewhere..try a new headset first..

Your phone is trying to connect to a TFTP server address to download a firmware and/or config file update. You need to figure out what IP address it is trying to connect to (You may have to use wireshark or another packet sniffer to determine this).

Once you know the IP it is trying to connect to, you'll need to set up a small network with a TFTP server running on that same address, and feed the phone a firmware update and/or config file. It will likely not fully boot unless it gets a firmware update.

According to the Jabra website, 0000 is the passcode for all of their products.

If the 7941g is the cisco cp-7941g ip phone then no you can not since the ip phone only has ethernet connections and the airap1131agak has only wireless connections on it as it is a wireless access point, so you will need a wireless router or something similar to get the wireless to ethernet cable.

Unfortunately this is a very common problem with Cisco's IP Phones. It can be caused by either a faulty hookswitch or a damaged jack. Both of these problems can be remedied by contacting IdacomUSA.

Try configuring CCM IP address either trough DHCP parameter, or Network configuration on the phone.

the first problem will be to check or replace the cable that you use to connect the phone or check the jack that you use
