  1. Android client getting blacklisted

    Device registers fine otherwise. I did whitelist the local IP range the client would use in the office then she got blacklisted at home. I can clear it and it will be fine for a few days. Randomly a few days later her phone will drop a call 30-45 seconds in then blacklist her IP for...

  2. Connecting to car, tries to dial self

    This just happened again and for me it isn't related to 3CX. This looks like a bug in Google Voice. I was able to repeat the scenario several times. If I have Google Voice open and in focus when my phone connects to the vehicle Bluetooth it immediately dials itself. I repeated this on three...

  3. Android client getting blacklisted

    I've set verbose logging and get nothing more than authentication error. Incorrect user name and password when this occurs. This user has a Google Pixel and is the only one usimg that particular handset. I've had the user uninstall the app, reinstall and reprovision and the problem randomly...

  4. Connecting to car, tries to dial self

    Just curious if this issue ever came back for you? Oddly enough I've not changed anything as I wanted to try and catch the scenario it occurred but haven't had this issue pop up again. Both vehicles the problem occurred in are GM brands. Was yours in a GM or different brand?

  5. Android client getting blacklisted

    Anyone ever have an issue with an Android client getting blacklisted for failed authentication attempts? This is a legitimate extension and login settings are correct. But maybe once a week the user will try to place a call, open the app and get the waiting on network message. I log into the...

  6. Connecting to car, tries to dial self

    I do not have that enabled and it happened again today.

  7. Connecting to car, tries to dial self

    I have an S9 that sometimes does this. When I connect to the car via bluetooth it will dial itself. i haven't figured out the circumstances that cause it and the car itself doesn't show to be in an active call. Its only when i try to listen to the radio or Android Auto and get no sound so I...

  8. Solved IP range for 3CX hosted SMTP servers

    Thanks!!!! That just helped me out also. I sent an email about this but of course didn't get the response due to the inbound IP block.

  9. WEBCLIENT: DOCUMENTATION!

    Inbound to the 3CX host.

  10. WEBCLIENT: DOCUMENTATION!

    I finally got it to work. I found a link that showed you also need to forward UDP 48000 - 65335 for WebMeeting. Once I added those the WebRTC would work and could make calls on a headset through the web page. The post at...

  11. WEBCLIENT: DOCUMENTATION!

    I've tried this on two different computers with headset and laptop issuing built in mic/speakers. I can't get audio on either side. The dial pad tones and ringing will play from the WebRTC connection, call will connect to the number dialed but no audio. Firewall checks are good and connecting...

  12. Polycom VVX300

    DHCP is done by a Zyxel appliance which doesn't have the Option 66 available. I put the provisioning link in manually also. The line shows active on the phone display and 3CX is reporting it connected and online on the web portal. It just doesn't make or receive calls. I haven't dug into this...

  13. Solved 3cx SIP ALG

    I was curious and just ran the firewall test on a unit that has always passed. No changes made. Failed.....

  14. Polycom VVX300

    I had a pair of Polycom VVX300 sitting here from an old 8x8 account. I was able to factory reset them and get into the GUI to set the phone up but for the life of me I can't get this thing to make or receive calls. I never could get it to pull the registration direct from my 3CX server. This is...

  15. Solved Forward calls to an external number WITH extenstion

    I did a search and the last relevant info I found was from about two years ago. Not sure if anything has changed on this. I have an extension that I need inbound calls outside of business hours to forward to an external number which also has an extension. Can the current version of 3CX add a...

  16. Your largest install...

    What is your largest install and was there anything learned in the process that had you known before would have made it easier? Backstory..... I've setup 3CX for a few friends and family at their smaller businesses usually without drama and all have been happy with it. Most have between 5 and...

  17. Try Out the New 3CX SIP ALG - Firewall Check

    Zywall USG50 - Works. It will show the ALG failure when enabled and passes when turned off.

  18. How to trace a service stop?

    One day I received a notice that the SIP service stopped. All the other services were still running and the SIP services started back up manually without error through the web portal. This has only happened once and has been the the ONLY issue this system has had in the six or so weeks since...

  19. What's your preferred installation method?

    I'm testing this out and so far have installed using the Debian/3CX iso on a Hyper-V VM inside Windows Server 2012r2. I haven't yet tried to install it directly on the server core or on the VM for the domain controller. My first VM was set running two processors and 2048mb of RAM. I only had...

  20. Block incoming call per country

    I would like to see it for extra security on the backside. If we have no employees outside the US or any that would even be traveling outside the US then I would like the ability to refuse connections of any type from foreign IP ranges. My current firewall can't do this but am looking into it...
