    hey guys

    I am currently trying to setup this :

    I have a sip trunk provider in my city who installed a cisco modem for the sip trunk.
    the ip address of the modem is XXX.XXX.24.57 255.255.255.248
    outbound proxy is XX.158.128.41
    ip address that i can use are .58 t0 .62

    i connected the sip trunk provider modem to the WAN interface of a Adtran Netvanta 3120 and i connected my switch to a switchport.do i programm the WAN interface as XXX.XX.24.58 255.255.255.248 ?
    3cx phone system and my phone are connected to the switch



    in the 3xc : for the voip providers SIP server hostname or ip : do i put XX.XX.24.57 ?
    outbound proxy : XX.158.128.41
    i need no authentication
    i disabled STUN

    First off, it is not a good idea to post your fixed public IP, in the forum, you should edit, and XX out a few numbers.

    If yourpublic IP is the 172.122.XX.XX IP, then that is NOT the SIP server host name.

    Who installed the modem, an ISP or your VoIp provider?

    You should have an IP, and your SIP Provider should have an IP. It is not always necessary to use an outbound Proxy, the information, on what to put where, in the 3Cx trunk datafill, should be given to you by your VoIP provider.

    It usually consists of, the SIP server, sometimes a Proxy server, sometimes a user name (number), and generally a password or authentication ID/name.

    Is the Adtran Netvanta 3120 a router,or simply a switch/firewall?

    the voip provider install a modem in each customer location so the internet access is independant

    and the netvanta 3120 is a router with 1 wan interface and 4 switchport
