A2Billing has limited support for voicemail.
I have it working right now, except for two things:
1. Ability to set ring time before a call goes to Voicemail
2. When customer calls in to system to check their voicemail, they are being prompted for their mailbox. I will like them to be automatically recognized so they only need to put in their password.
The system is running A2Billing 1.94 and FreePBX. Free PBX is set to send calls to A2billing.
Please reply if you have experience specifically with voicemail within A2Billing and you can help.
