External Voicemail access

User on a phone away from the office, with no data access, needs to change voicemail message or check their voicemail messages.

Since there is no data access, emailed file or user portal isn’t an option.

Customers have had this functionality in the past either on different asterisk distributions or their legacy analog systems, and would like to have this on VitalPBX.

I’m guessing this would be a modification to [sub-vm] in extensions__20-baseplan.conf or override it somehow

something like 

[sub-vm]
exten => s,1,NoOp(Leave a Voicemail)
same => n,Voicemail(${ARG1},${ARG2})
same => n,Return()

exten => a,1,NoOP(Leave a Voicemail)
same => n,VoicemailMain(${ARG1})
same => n,Return()

Cell phone with no data access.  Softphone is not an option.

User calls into the system and is transferred to their extension (receptionist, no IVR), waits for voicemail greeting to start, then would press * to interrupt and system asks user for their password (this is how it works on an old freepbx box I have).

I’ll give that a try.

Thanks
