I've noticed that despite having voicemail enabled on an extension the phone itself just rings and rings and rings, with voicemail never picking up. I can, from the device itself, press the voicemail key and setup my mailbox greeting, etc. But no matter what the call is never handed off to voicemail.
Anyone have any pointers on where to start with this problem? Voicemail is turned on for that extension. Ring time is set to 15 seconds. Password is set and works fine for checking voicemail. But alas, I cannot ever get the device to stop ringing so I can leave a voicemail.
