If I set up an Asterisk server with a basic Digium TDM01B: TDM400P + 1 PORT FXO and people only dial into the server for voicemail using a SIP from Broadvoice or another SIP provder. Can multiple people dial the SIP number without getting a busy signal? I just want a vmail server that 1-50 people could potentialy be connected to concurrently. Thanks!
That sounds like a question for Broadvoice to answer.
If they allow multiple incoming calls, then yes. If they don’t allow multiple incoming calls, then no.
Contact Broadvoice. You may find that you have to setup multiple lines to support multiple connections, or they may have a service that allows multiple incoming calls.
