We are having an issue where a call comes in and we can only hear one side of the conversation. BUT you can put the call on hold and pickup the call will work perfectly.
We have the article and the proper ports open. The one sided calls happen randomly across all our locations (500 plus users) and they are always desk phones. We have not tested the speaker phone test but placing the call on hold and then off works every time. One time I placed a normal call on hold and the call went one sided. I just placed them back on hold and was able to pick up.
Nope the phone(s) are new and the cabling is too. I first thought is was just our locations but when it happened to me I had just put the person on hold and picked up they could not hear me till I put the on hold again. This was on my desk phone with a 250meg fiber circuit Vlan'd.
Had another batch of calls come in that were one sided. The location put them on hold and that fixed the issue. This was our NY locations. I looked at the logs and the calls completed ok and showed no issues. Any news out there why this is a strange fix and how do we stop the one sided calls?
