    I have an RV042, connected to 2 x Different Broadband suppliers.

    One of the Broadband connections is my Voip provider and I wish to Bind all VoIP protocol over that WAN

    So far I have binded:
    5060-5070UDP to WAN1 (VoIP provider)
    9000-9100UDP to WAN1 - RTP traffic
    All other traffic to WAN2

    This appears to work perfectly accept for my external extensions. (Based at a different location connected by internet and another RV042)

    They can ring in to and from my Phone system however the RTP trafic seems to get lost.

    As far as i can tell from my Router logs and WireShark log it appears that the RTP traffic is trying to use my WAN2 (All data Broadband not my VoIP Broadband) obviously if the phone is trying to talk to a different WAN the phone system is not going to be able to communicate.

    It has to be a binding problem as if I disconnect my WAN2 the external extensions work correctly.

    And until this weekend I have had no Protocol Binding in place and only WAN1 ( VoIP Provider) in-place it has been working fine.

    Further information:
    I am using 3CX phone system
    VoIP Unlimited Broadband and as VoIP provider
    BT is my external Broadband provider and my WAN2 at my site hosting the Phone System
    I am based in England

    Hope someone can help! Thanks
