Just want to create a post to see if anyone else has noticed this issue.
Issue #1: Audio quality out of the speakerphone of 8800 series phone is noticeably worse than 7900 phones.
Issue#2: I am having users report of a popping/crackling noise during calls out of the speakerphone. I have also experienced this myself on my 8861 phone.
Issue#3: There is a subtle buzz/vibration noise coming from the speakerphone when going off-hook and just listening to the dial tone of 8800 phone.
I suspect that there is a hardware issue with the actual speaker of the speakerphone of the 8800 series phone. I have 8851 and 8861 phones deployed and have had this reported on both models.
See attachment of what the popping noise actually sounds like which I recorded with an iPhone while it was occurring on my 8861 phone.
The popping noise is pure random and I am unable to reproduce it on demand.
I am currently running sip88xx.10-3-1-20 and UCM 10.5.1.11900-13
