Cisco 3725 can act as a Voip gateway ?

Discussion in 'Cisco' started by Alberto Rubinelli, Nov 5, 2007.

  1. I have a Cisco 3725, with a wic 4B-S/T ,4x BRI ISDN
    It is possible to configure it to act as a gateway for Voip traffic to
    and from isdn lines ? (using an existing SIP server).

    Thanks

    Alberto

    SIP server is on the internal network, the lan connected directly to
    Fast Ethernet 0/0 port of the Cisco 3725

    I presume that you will need DSPs.

    Definitely no way to do without then with an ISDN Pri.

    If I add a DSP board to the 3725, I can configure a ISDN gateway with
    the existing 4B S/T ISND BRI ?

    Thanks
