Unable to see Caller ID when listening to voicemails? T48S

[jolouis]

Voicemail is handled by your PBX; all the Yealink phone does is place a call to the voicemail mailbox access number. From the phone's perspective this is no different from any other call, and once dialed the display simply shows the call status and normal transfer/hangup/etc options.

Visual voicemail, which is the common term for the kind of thing that you are looking for, has to be supported and provided by the PBX. Contact your service provider or PBX vendor to see if they have support and can configure/activate it for you.

In many cases voicemail to email, which is also a common PBX feature, may prove to be even more useful as often such emails will include caller ID, call time, etc as details of the email body along with the recorded message attached. Same thing though you need to contact your service provider or PBX vendor about that.
