5gt elastix sip



  • Hi everybody

    We are configuring Juniper Netscreen 5GT to allow VoIP traffic via elastix PBX

    The elastix PBX has local address 192.168.1.8, which I associated with its external IP, a.b.c.d by way of a VIP, on the Juniper.

    Diagram

    Mobile (a.a.a.a) –- INTERNET — (a.b.c.d)WAN–5gt–LAN(192.168.1.1/24) —INTERNAL— A.) Elastix PBX (192.168.1.8), B.) LinkSys IP Phone (192.168.1.101)

    Mobile (a.a.a.a) – extension (123)
    LinkSys IP phone – extension (456)

    Before replace netscreen 5gt

    both extension register the elastix PBX successfully.
    extension (123) call --> extension (456), ring ok, connect ok, both-way audio ok
    extension (456) call --> extension (123), ring ok, connect ok, both-way audio ok

    After replace netscreen 5gt
    both extension register the elastix PBX successfully.
    extension (123) call --> extension (456), ring ok, connect ok, both-way NO audio
    extension (456) call --> extension (123), ring ok, connect ok, both-way NO audio
    and
    drop / disconnect call after 30 - 33 second.
