I have an odd CUE issue.
When calling the auto attendant from a cell phone and pressing * for VM access, most of the time it transfers (makes ringing noise), then hangs up.
This works fine on "land lines".
Occasionally you get through... but when you do you only get the first couple words, then it goes garbled, and then silent.
This is on a UC560 using SIP for PSTN.
A SIP capture of both call scenarios look the same except for the UC sending a "BYE" on the cell calls that it hangs up on.
Has anyone else experienced this?
Any tips for troubleshooting?
For the record, this isn't a single cell phone -- it is everyone.
