    does anyone know where I can find documentation of templates on Yealink phones? I can't find it on Yealink website and 3CX won't say what to do.

    So the VPN essentially makes your phone connect over a private network instead of public Internet. Was security the only reason you selected to do it over IPSEC VPN or was traffic flow also in the consideration? The customer already has desk phones that they are used to so can't ask them to use...
  3. Audio issues & General advice

    Ok, I will try all of those one after the other to see which works best. As for the options I outlined, which one would you prefer to try? What are your thoughts of bringing the 3CX inhouse instead of hosting it on cloud?

  5. Audio issues & General advice

    Thanks for the comment but when I registered using TCP, it wouldn't work with the door entry system. The video and audio worked fine but DTMF didn't. Since we need to send DTMF tones to the door entry system, it wouldn't allow us to open the door using the phone. The comment about the T49 was...
  6. Audio issues & General advice

    Hi We have implemented 3CX for a customer who is all of a sudden having audio issues. The caller can't hear the speaker but work the other way round. If a call comes in and works fine, when transferred we have same issues. On a T49 which is non supported but works fine as SIP extension, all...

  8. T49G SP Issue

    Hi Michael Thanks for your help. This worked perfectly fine. The only issue I am facing now is that the phone loses its registration with the server after a while and we have to reboot the phone. Once the phone gets rebooted it starts working again and stops working after a while again. I...
  9. T49G SP Issue

    Hi Michael Thanks for quick response !! I just read on another post to use TCP instead of UDP and voila...the phone appears as registered. But back to your suggestion, isn't SBC built-in to 3CX? is it separate piece of software and if so, how do I use it in my setup? My 3CX server is...
  10. T49G SP Issue

    Hi Jason Can you tell me what settings did you do on T49G to get it to register with a remote 3CX server? for me it keeps failing and can't find any logs on either the phone or 3CX to understand why. Any help would be appreciated !!

    Hi YianniSH I am doubting that 3CX allows manual registration. When I try manual registration, the SIP registration from a T49 fails with 407 proxy authentication error. Your support team says it happens because the phone isn't supplying the correct authentication details which were created...
