  1. Implemented 3CX mobile Client - Roaming 4G/WIFI

    As mentioned before 3CX clients use the tunnel protocol. Sending the sip and rtp traffic thru the tunnel solves most of the rtp, NAT etc. problems. It should be relatively easy to enhance the tunnel implementation in a way that it supports the change of IP-addresses and networks. P.S. IMHO the...
  2. v16 Linux Firewall best practice

    We have switched our 3cx pbx from Windows to the official 3cx Debian iso. After the setup I checket iptables configuration and saw that it contains some preset rules. Unfortunately many of the rules make no sense to me. Examples: Duplicate entries Destination sip.mcast.net in INCOMMING chain...
  3. Multiple Trunks help

    Hi John, Thank you for your fast reply. I am aware of the mentioned document and I went thru it several times. What I was finally trying was to identify the trunks by the host part of the contact fields, with no success. In the meantime I have been able to make it work. The solution was to...
  4. Multiple Trunks help

    I have a hard time getting multiple trunks to work. All of my approaches have failed so far. Thus it it time to ask for help. My settup is as follows: Trunk 1: SIP Provider with registration Trunk 2: Second SIP PBX, IP-Based without registration Outgoing calls are working fine, incomming...
  5. Trunk to trunk port forwarding

    Done. Results still the same. In the meantime I have found the following document: https://www.3cx.com/docs/sip-trunk-inbound-calls/ With call source identification set to map from:user-part to authentication-id I was able to reach the right trunk. Now, incomming calls to outbound numbers...
  6. Trunk to trunk port forwarding

    Thank you for the answers. @JohnS_3CX I have configured a bridge as described in the Asterisk example. Working for internal calls but still not for outbound calls. Additionally, using the bridge cause problems with caller-id, since the legacy pbx does not support remote-party-id (supported are...
  7. Trunk to trunk port forwarding

    Hi, Our 3CX pbx has a trunk which is connected to a public sip provider and a second trunk which is connected to our legacy pbx. Public calls from 3CX clients are working, as well as internal calls between 3cx and the legacy pbx in both directions. What I am trying to setup now is that public...
  8. OPUS codec support and usability in v15.5

    @YiannisH_3CX Thank you for the hint to "chrome://webrtc-internals/" Since we have a mixed experience with webclient audio quality I have started a debug session with it. What I have figured out so far is that the call leg of the caller uses opus and the call leg of the callee uses PCMA...
  9. Provisioning QR-Code Problem

    Firewall check is ok. Yes. phones are provisioned remotely. This is working fine by using the email attached config files. The only thing that does not work is the qr-code provisioning. We are using split dns entries and resolving works fine. The only problem as already mentioned is that both...
  10. 3CX v16 Reloaded: Alpha 2 Lands

    Since your are greatly improving the look and feel of the webclient in v16 I would appreciate if https://www.3cx.com/community/threads/webclient-phonebook-improvements.62135/ could be addressed as well.
  11. Provisioning QR-Code Problem

    In our setup, the qr-code provisioning of 3cx-clients does not work. The problem is the hostname of the encoded link. It seems that the hostname is hardcoded to the hostname of the server. This does not work for us since we use a common dns name for the 3cx service. Example: Server-hostname...
  12. Webclient phonebook improvements

    The usability of the webclient search function is very limited because: - One line per contact and number without showing the type of number. - Missing company name. As an example I have created two contacts: Contact 1: FirstName: John LastName: Doe Company: ACME A Contact 2...
  13. Implemented 3CX mobile Client - Roaming 4G/WIFI
