Voip and load-sharing per-packet

    I have two routers 1760 which connect together via two T1s with
    load-sharing per-packet option. The documentation says that this may
    cause problem with VOIP because of arriving-disorderedly packets.

    In my case, I do have some phones using voip. These phones are on one
    side connecting to the phone server on the other side.

    Is it possible to specify all connections to a specific ip address (
    the address of the phone server ) not to use load-sharing per-packet
    options ?

    Thanks for your advice,

    You are introducing a situation that guarantees jitter and voice cutting in
    and out.

    Absolutely.

    Run all RTP traffic over one of the T1s... just PBR matching on UDP ports
    16384 to 32768 and specify its next hop to one of the T1s...
