    I am still very new to this technology. All this lab is on an internal

    X-Lite Software Telephone -
    Cisco Fast Ethernet -
    Cisco BRI connected to the ISDN Line Simulator with numbers 384001 and

    I've seen and searched for several scenario's etc. I have a doubt as
    some articles quote that I should use a SIP Proxy as well (like OnDo
    Sip Proxy) and some quote that the cisco router can do all the routing

    Any Idea from where to start such project? Up to now all i managed to
    do is configure the router (2821) lines etc, but i dont know what i
    should do more regarding VoIP, authentication and all the rest. Does
    anyone know of any article/tips or whatever that can help me?

    Below is part of the router configuration related to VoIP.

    Note: in this particular scenario I was trying to work with a SIP
    proxy, but still nothing is working and I am not sure if this is the
    correct way I am working.
