Thread: SIP PBX?

  1. #1

    SIP PBX?

    A company I am working with will be routing PSTN calls to me via SIP. I want a PBX to receive these SIP calls and deliver a short voice message, as well as give the callers the option to leave a message for me. I would like this PBX to handle up to 50 simultaneous callers. So far I have figured out that I need to install Asterisk (or similar) to serve as my PBX. Where do I go for a SIP account that can handle 50 SIP callers at the same time? I will not be making any outgoing calls.

    Do you definitely need a SIP account? If the company you are working with will be sending you the calls via SIP they can go directly to your Asterisk server.

    set up a SIP Trunk between you and the company sending you calls (you will need a login to their system if they require SIP Registration - they can also possibly do IP-based authentication)

    The number of channels can be confgured to whatever you can support - and whatever your PSTN Gateway/Terminaton provider is willing to support

    Asterisk has got issues with Voicemail, instead use FreeSWITCH which scales up quite pretty.

    Take care to have adequate bandwidth to your ISP/provider.
