We have setup several of these devices for our users and only one of them is having this issue. When an intra-company call is made to this persons phone and they pick up the call with their headset and the remote lifter, they are getting a dial tone and not the call that is coming through to them. If an outside call comes through to them, the call is answered fine on the headset. If they use the handset instead of the headset, the intra-company call is received fine as well. I swapped the Jabra with another one to rule out the device but the issue continues. What we have them doing currently is go ahead and answer the call with the headset which causes the lifter to pickup the handset and then they hit the IC button on their phone and they can then talk to the calling person, but no one else has to do this on their phone. The phone is an Intertel 8520. Any ideas on the setting that apparently needs changing to fix this?
