RBR50 WiFi Calling Quit Working

Our WiFi Calling capabilities stopped working yesterday on both mine and my wife’s iPhone 6s cell phones that are running current iOS version 11.4.1. WiFi Calling had been working quite well since purchasing our Orbi system in October 2017. I have reset the router twice, once through the interface and again with hardware using the reset button and a paper clip. I have taken my phone to another network and WiFi Calling works there. Our Orbi is running firmware V2.1.4.16. and the one and only satellite is as well. I called my ISP and they did not feel anything on their end was causing the problem since my internet connection was working great otherwise.

 

Any ideas what I should try next?

 

Thanks,

Doug

  • I'm in the UK on EE. I couldn't get Wi-Fi calling to work until I changed one of the settings... unfortunately I can't remember which one of the two settings it was...

     

    it was either:

     

    NAT Filtering - Disable SIP ALG

    -or-

    Disable IMGP proxying

     

    Both are on the Advanced > Setup > WAN Setup page

      Googling around, I think it was "Disable SIP ALG".

       

      I couldn't get WiFi calling to work at home, even though it would work at the office.

       

      I came across this article that indicates that it's poorly implemented on many routers:

      https://www.voicehost.co.uk/help/sip-alg-and-why-it-should-be-disabled-your-router

       

      I enabled the "disable" option, and it all started magically working.

       

      Note: I didn't disable Port Scan and DoS Protection as the post also suggests... that doesn't sound like a good idea

        Thanks for the suggestions. I located and made your recommneded changes but WiFi Calling still is not working. I will keep looking for ideas.

         

        I am still not convinced my ISP has not inadvertently made some update that is causing this. I will try to get my hands on a different router to see if it is the Orbi or not.

    hat is the Mfr and model# of the IP modem the Orbi is connected too? 

     

    Has the wifi calling been working on FW 2.1.6.14? When was the FW updated on the Orbi? I presume if wifi calling had been working on v.14 and nothing else has changed on the Orbi, that your problem maybe with the phones or the ISP...

    I have wifi calling enabled on my 6sP and its working. 

     

    SIP should be alwasy enabled as it's for voice communications over routers.

      I don’t recall when the firmware was updated, so I know WiFi Calling has worked since the last update to v.14.

       

      My ISP setup is kind of unique. I live out in the country and have a wireless broadband service provider. And this ISP leases space on my tower. So, as part of the lease, I have a cat 5e cable running from my Orbi router out to the tower and into an ISP owned switch. It is small cheap Dynex DX-GB8PRT and has several items connected, service to me being just one of the items.  That switch gets its input from something installed up the tower.

       

      I have set the SIP back to default of being on after my test.

       

      Thanks,
