I am having a weird issue with a Cisco 9971 phone. I managed to get most of it working, including the side car, however one of the issues is that there seems to be some sort of side tone / beep occurring roughly every 13 seconds or so, as if the phone is activated with call waiting.
However none of this is activated and is still making the annoying beeping side tone. The phone does require that one runs with tcp=enable and transport=tcp, thus turning on the presence information, which from the logs seems to be refreshing roughly every 10 – 15 seconds. However the “Patch” has not been compiled in, thus the information being sent to the phone is incorrect and thus am wondering if this is what is causing this annoying side tone.
If anyone knows, please let me know or anyone has any experience with the IP Phone 9971’s .. Would be awesome to get this working correctly
