Which extension do I need to dial to get voice mail, thanks!
If there are any predefined extensions, they will be defined by FreePBX, which is supported at https://community.freepbx.org/ not here. Asterisk itself is a toolkit, and doesn’t have pre-defined extensions numbers.
Hi, David, How can I listen to my voice-mail with my sip-phone?
Call an extension that invokes the VoiceMailMain application, with appropriate options for your specific use case. You will need to define this extension yourself.
Can you give me a setup guidelines? Thanks David.
No I don’t do paid consultancy.
For bare Asterisk you should look at the sample configuration files that come with Asterisk, and definitely include this.
For FreePBX, I repeat that this is the wrong forum; we are not experts on how FreePBX uses Asterisk and how it limits what you can do with Asterisk.
Got it, thanks David!
