IP phone not picking IP

Hi experts,

I have a strange issue.

I have a user with IP desk phone like everyone else. His phone keeps going into a look trying to access DHCP and it does not find it. If I get another IP phone and plug it. This will do the same.

I just want to know in general what is the issue?

I plugged the patch port to another port in the switch that has another working phone and it did the same thing. What could be wrong.

Make sure the network cable is plugged into the correct port on the phone, You can use the other port to plug into a computer. The phone should be plugged directly into a port on a wall.  check to see how the working phones are plugged in and make sure it is plugged in the same way.

So when the same fixed cabling was put in a different port in the switch is still didn't work?

Suggests to me that there's an issue with either a patch lead or the cabling in the wall, one of the pairs might not be working correctly. Start by replacing the patch lead at each end (as it's cheap), then if no good perhaps get the fixed cabling checked / re-terminated.

One other thing you can try is: Try one of the working phones and plug it into this port, or plug the phone that is not working and plug it into the port where there is a working phone. If the non working phone works in this new location you know two things that the cable and the phone is working. If the phone works in neither location it could be a bad phone or a bad patch cable. Compare how the working phone is plugged in on the working phone.
