Dual-WAN Fail-over SIP Phone registration issues to cloud

  • Hello again everybody,

    I have dual wan setup as fail-over only and it works fine for all devices except for my SIP phone registrations (running 2.3.4-RELEASE (amd64) ). I believe it may be related to timing for the failover, and possibly if it fails back too quickly. The Phones register to an external SIP provider, and when the primary internet goes down, I don't believe they are registering via the new IP address from the secondary WAN connection. I can't determine the best coarse of action to avoid SIP registrations and timers, so if the WAN1 comes back quickly the phones just don't know what to do, or stay registered on the backup connection, or don't reregister when the fail-over occurs.

    Are there some tuneable parameters as far as how long to wait for each fail-over so my SIP registrations succeed?

    I don't know the best action for this, but was hoping that SIP fail-over would be pretty seamless but that's not the case.

    Thanks for any help!
