Thread: Gateways de-register

  1. #1

    Default Gateways de-register

    hi all

    i have a very annoying issue on one of my quadro 16xi's
    on this unit i have a 6fxo gw and a 5 isdn gw

    the main unit is on fw 5.1.39
    the fxo gw is on 5.1.13
    the isdn gw is on gw 5.1.14

    the gw's is setup in pstn sharing.
    the proble i have is as such, every now and then, 2-3 days one or both of the gw,s wil de-register from the main device and delete all inbound and outbound rules from the routing table. i then have to reboot the gw's, and resetup the routing table.
    the routing table i simply upload from ecf manager,but it gets annoying since no-one can then phone in or out till i get to fix it

    can anyone tell me why this is??

    Corne, Whats happening on the network switch where these devices are connecting ? is it a good named brand device that has a UPS attached before the power company to the switch and your Quadro devices ?

    I suspect the mac table is getting corrupted and doesnt know how to get to the devices or something along those lines. Bad power that might be under voltage or over voltage.

    If there are fluctuations on the power then it might be the cause of things to go astray.

    I have the exact same issue, this only seemed to start after the latest Firmware update.

    The Gateways and PABX are running off an APC UPS, (both off the same one) this only happens to one of them at a time.

    Is there any way to get an alert if a slave loses Registration?

    ------ my other post---

    External PSTN Gateway Losing Registration
    I have a Quadro 16xi PABX and two QuadroISDN Gateways.

    Both are running as Slaves to the PABX. Everything was working fine for some time, then a couple of weeks ago one of the ISDN Gateways lost its registration (simply became unregistared). Everything I tried didnt work, I confirmed connectivity to the PABX (ping tests) I tried re-entering the Auth Details, etc. Once I rebooted the GW, everything came right ( i had to redo the Call routing Rules on the PABX and the ISDN line config).

    This morning the other one did the same thing. Very strange.

    Quadro 16xi Firmware: 5.1.38
    Quadro ISDN GW Firmare : 5.1.14 (both are on same version)

    Nothing shows up on the event viewer on the PABX, any ideas where I should look next?
