After update from V18 to V20 when clicking on "Edit Trunk" you get kicked back to the people page.
Reason
- The template previously used is not anymore present in the system
- Parameters of the template used, did changed
Fix
- Click on the dots and select "export" to get the file (it will be named as "provider.pv.xml")
- Rename the "provider.pv.xml" file to "vtx.pv.xml"
- Once file is renamed, upload it to /var/lib/3cxpbx/Instance1/Data/Http/Templates/provider
Afterwards you should be able to view and edit the sip trunk again

Registration problems from time to time (irregulary)[edit | edit source]
Problematic:
Everything is working great, but from time to time your customers get the message when trying to reach you: "the number you have dialed is not reachable, please try again later".
Or if you try to call out: "Call could not get established"
Information:
If the template choosen is using "Any" for "Transport Protocol" it is using UDP by default.
Soluntion:
change "Transport Protocol" to "TCP"
Reason: the "Re-Register timeout" setting in the system is not taken count when using "Any" (which is UDP) and reregister interval is only 30s. As this is shorter than the transaction timeout for retransmission, it can lead to registration problems.
