Hello,
Lately we have received some complaints about WiFi Calling not working on our wireless system. We upgraded to 8.10.0.2 recently and some of the reports coincide with that, though it's always difficult to tie down exactly when the issues began.(always tempting to blame an upgrade of course!).
As far as we know Wifi Calling has been working up til recently, it has been configured for a while now, but testing today between colleagues phones showed that the call could be made, but once connected there was no sound (either for caller or receiver - maybe a second or so of sound right at the start but then nothing). WiFi Calling appeared to work on these devices on different wireless networks (not on our system), so it seemed to be related to our AOS system. Interestingly WiFi Calling from WhatsApp seemed to work, at least in our testing. But not using the phone's phone app.
A colleague found that adding voip-applications-acl and wificalling-acl to our user roles appears to solve the issue (at least on our dev system), and that is mentioned in the config instructions, though it says the voice role has this applied by default. Should Wifi-Calling users receive the voice role? Should we neeed to add these ACLs to our user roles? We're a little confused as to how come it was working previously if this was necessary. Does anyone know if anything has changed, or had similar reports?
Thank you
Guy
